Airfal’s ATEX high bay triumphs at the Hannover Messe

Airfal International returns from the Hannover industrial fair satisfied with the results obtained and with a clear winner: the ATEX LED MAX  high bay for zone 2, 22. This model stands out for its resistance and versatility since it can be installed as a hood and as an industrial projector.

Lumen calculator (Lumen to Lux to Candela)

The Lux or Candela lumens calculator below will help you choose the lighting solution that best meets the specific requirements of your installation. Airfal offers a wide range of high quality and energy efficient LED lights for a wide range of industrial applications and to meet multiple technical requirements.

With this calculator, you can convert a lumens value of a product into a lux value if you know the beam angle and measurement distance. Enter the distance and angle of the beam, then enter a lumens value and click on’Convert to Lux’ or a Lux value and click on’Convert to Lumens’. You can also convert to Candelas.

Lumen Calculator (Lumen to Lux to Candela)

Iluminance (lux): the iluminance refers to the incidence of the light flux on a surface, per unit of surface
The unit of illumination is the lumen per square metre: lux (lux). A single lux is equal to one lumen per square meter.

Luminous flux (Lm): Total amount of light emitted in all directions by the light source. The lumen (unit lm) gives the total luminous flux of a light source by multiplying the intensity (in candela) by the angular span over which the light is emitted. .

Here are some examples:

Candle 12 lm
Incandescent lamp 60 W 750 lm
LED 1 W 130 lm 130 lm

For example, a 1 candela light source will produce 1 lumen per square meter at a distance of 1 meter.
A lux is equal to one lumen per square meter (lux = lumens/m2).

Luminous intensity / Candela: Candela is the base measurement for describing luminous intensity.  It tells you how bright the light source is which shows how far away from an object you can be and while still being able to see it.  The unit is the steradian lumen, better known as candela (cd).

The luminous intensity of a candle is 1 candela

Essentially, as the light moves from the transmitter, it disperses into an area. The further away the light has to travel, the more it will be scattered. Therefore, the amount of lux in an area or on a surface can vary depending on the distance travelled by the light and the angle with which it is dispersed.
When the lumens supplied by a given transmitter are the same, light that travels less distance and/or is more narrowly focused will appear brighter because the luxes are concentrated in a smaller area than light that has travelled a greater distance and has been scattered over a larger area.

Beam angle: The beam angle is the radiation angle of a light source. For example, a beam angle of 30 degrees means that the light is shaped like a cone and its edges form a 15 degree angle with the central axis. A change in the radiation angle affects the light intensity (lux) of a light source but not the light flux (Lumens).

Luminaires with Class II LED modules and DALI dimmable: which issues do they raise ?

In recent months, customer demand for luminaires with Class II LED modules and with DALI dimmers has increased, something which Airfal’s technical department advises against due to the lack of guarantees for their correct use.

To understand better the situation, it is important to know what a Class II luminaire is.

Class II luminaires are characterised by additional safety measures such as double insulation or reinforced insulation. This type of insulation is mainly intended for manual electrical appliances, where extra insulation is required as they are used by people for many day-to-day activities.

Thanks to this double reinforcement, it is not necessary to use a ground connection when installing luminaires with Class II insulation. They do not depend on space conditions, which means a significant saving of time and, above all, of money when installing them.
However for some electrical appliances and installations it is recommended to use Class II insulation, such as lighting in the interior of a swimming pool. However, the use of Class II is not recommended for luminaires with LED modules and DALI dimming.

The elimination of the grounding of the installation can cause various electronic malfunctions and this implies several drawbacks and for that reason Airfal advises against this practice.
In the case of luminaires with LED modules, the reduction of Electromagnetic Interference (EMI) cannot be guaranteed by suppressing the earth connection, so it is not possible to comply with the relevant regulatory requirements. On the other hand, the grounding of LED luminaires ensures that the phenomenon of “LED GLOWING” or ghost lights does not occur. This phenomenon occurs when the luminaire with LED modules continues to emit a residual light when switched off or on standby. In the case of Class II luminaires, it is impossible to guarantee that there will be no “LED GLOWING”.

On the other hand, in the case of transients or voltage/current peaks in the power supply network, the presence of grounding causes the filters of the LED drivers to act by reducing or eliminating them. Without the presence of an earth ground connectionn (Class II), any transient will pass through the driver and reach the LEDs, shortening their life span or even destroying them.
We see in this graph a simple explanation, being the left part without grounding, and the right part with grounding:

On the right-hand side with earth connection the transient arrives much more damped than on the left-hand side without earth connection.
In the case of Class II DALI luminaires, it must be explained that DALI drivers are very sophisticated devices controlled by a small internal computer. The control and regulation of the LEDs is carried out under the supervision of a software integrated in the driver microprocessor.
For the correct operation of these devices, the computer that incorporates it needs to “measure” the reference potential 0. Without grounding, the measurement may be inaccurate, and the dimming may fail or have uncontrolled random effects (Current differences between luminaires, synchronism faults…). We can find cases of correct operation in which regulation problems may appear after some time.

In addition, the standard governing a DALI installation (IEC 62386) specifically specifies the need to have an earth connection to protect the control circuits and drivers, as shown in the following figures:

As stated at the beginning of the article, the lack of guarantees for quality, uninterrupted lighting is the main reason why the installation of Class II, LEDs and DALI dimming is not recommended.

Lighting solutions for the food and agriculture industries

Quality office lighting: 5 criteria to take into account

There can be no quality office lighting without a lighting project, as it will determine the photometric characteristics of the installation.

In particular, the average lighting level to be maintained depends on the use and people. For example, lighting levels for older people are not the same as the ones for younger people.
Quality office lighting will maintain its performance over time. Today, the evolution cycles of buildings and their uses are faster.

Lighting must therefore be able to meet the needs of these different developments. For example, a lighting system that can be upgraded – which can be used in English – will be able to be connected later, even if it was not connected when it was installed. In fact, quality lighting will be achieved through LED sources. T8 and even T5 fluorescent tubes are no longer relevant.

Modern lighting

Finally, quality lighting is also modern lighting. Thus, LED sources allow innovative product designs compared to historical sources. Through the lighting, it is the image of the company that is conveyed, because it fulfills a decorative function beyond the functional aspects.

Advantages of quality office lighting

1 – No visual discomfort

First of all, thanks to the absence of visual discomfort, quality office lighting will enable users to perform the tasks assigned to them in an efficient manner. It is thanks to an appropriate lighting level and limited glare that photometric performance will be achieved.

2 – Employee well-being

Secondly, because lighting can create a pleasant atmosphere in work areas, it will contribute to the well-being of employees.

3 – Appropriation of space

Personalisation of lighting will be part of the work space of staff. With little cost, modern, high-quality lighting allows workers to really take over the space, because they will be able to adapt the lighting service to their needs. Benefiting from an adapted and comfortable working environment, employees will be even more efficient.

4 – Positive image of the company

A positive image of the company is also one of the advantages of quality lighting. With LED and automatic management systems, the company will provide an updates image. For example, by controlling the presence in offices and daylight, it will give a modern look.

5 -Energy and maintenance savings

Finally, quality lighting saves energy and maintenance. These savings are a benefit that results from a well run lighting project. However, they should not be an objective in themselves.

Productivity of farms: LED lighting is more sustainable and economical

lighting farm housesAccording to Airfal, lighting plays a significant role in poultry and hog production, and has a huge impact on the performance of farms. Adequate lighting is necessary to ensure the health and growth of poultry and hogs, as the lighting needs vary according to the stages of the breeding. A well-designed, energy efficient lighting system can mean better brightness, better performance and lower energy costs.

Lighting in poultry farms

World farmers are facing a price war and must reduce their operating costs as much as possible. To meet this challenge, some farms will be forced to expand, as for example, dairy farms that will double their average size. This development implies an evolution in the technical equipment of the farms, especially the lights.

For that reason, LED lighting, which is modern and ecological, is presented as a solution that can be broken down according to the layout of each farm.

To illuminate a space as large as a building for livestock, significant savings are at stake. IN addition, maintain lighting facilities may be expansive. In this context, LED lighting, which does not require maintenance once installed, allows the farmer to focus on the day-to-day tasks inherent in his operation. Solidity is also an important criterion especially in poultry houses. The savings are measured very quickly in the short term with low power consumption.

Compared to a compact fluorescent lamp, a LED bulb has a very long life span, depending on the model, from 25,000 to 50,000 hours, ie between 6 and 12 years of use. It also has the quality not to heat and resist shocks while having high light yields with few watts consumed. Finally, the LED installations allow a variable lighting which turns out to be a real advantage in a hen house, for example, where you have to simulate a sunset.

Lighting for cattle farms

There is evidence that cattle are sensitive to light in buildings and the best results in milk production and fertility are achieved with a 16-hour light cycle of 150 to 180 lux followed by 8 hours of darkness. Indeed, the lengthening of the duration of days by means of stable lighting influences the production of melatonin, the sleep hormone. By prolonging the duration of daylight in winter, melatonin production is reduced and cows are more active.

With the Farm LED light fixture, Airfal intends to limit the consumption of electrical energy. Compared to current (sodium / halogen) and fluorescent (neon) lamps, Airfal light fixtures saves up to 75% in costs. Indeed, the lifetime of the Led lamps, established at 80,000 hours and the superior production of Lumens per Watt (130 lumens / Watt) allow a lower energy loss in the form of heat.

Lighting in underground mines

lighting underground minesA characteristic of underground mining operations is that, as we move from the surface to the interior, the darkness becomes more complete, which is why lighting is a very important and fundamental factor.

Under these conditions, it may be interesting for mining companies to focus on a key aspect of the production equipment, lighting.

In underground mines, it is vital to have safe and efficient lighting. Airfal manufactures high optical performance luminaires adapted to underground mines. These Atex certified light fixtures meet the highest safety standards and are explosion proof.

Explosion hazard in underground mines involves the use of special lighting to avoid possible accidents. In coal mines, firedamp concentration can be high, resulting in explosive atmospheres, An explosion can be caused by mechanical or electrical sparks.

Inside the mine, where the atmosphere is potentially explosive,  electricity has to be used safely. To prevent or minimize the effects of explosions, besides mine ventilation, electrical equipment and lighting has to be specially designed for use in explosive atmospheres.

All electrical equipment and lighting used in the mine must be able to withstand an internal explosion, and prevent any risk of spreading an explosion, which is called explosion-proof.

Lighting standards help ensure the safety of lighting installations in mines. The lighting systems used inside a mine must comply with the ATEX directive, and avoid any risk of explosion or propagation. The ATEX normative (explosive atmosphere) is the result of two European Directives (1994/9/EC and ATEX 137) for equipment intended for use in ATEX zones and 100A ATEX 1999/92/EC or safety of workers).

With many years of experience in technical lighting, Airfal has created the Minex luminaire which has been designed  for use in hazardous areas. With low maintenance cost, easy installation, and maximum security, the luminaire Minex is compliant with Atex. It was created especially for lighting in underground mines. It can also be used in other industrial facilities, both indoors or  outdoors.

Led light fixtures for the mining industry

Effective mining companies must use the latest technologies, including a safe and effective lighting system. The main characteristics of a lighting system for mines are safety, durability, efficiency and long life. Such elements are essential to survive in the harsh environment of the modern mining industry.

LED lighting is extremely popular today in the industry and in particular in mining, because of the many technical advantages of this technology. Increased longevity, efficiency, energy savings, respect for the environment are some of the many benefits that can offer LED light fixtures for mines. Airfal offers a range of lLED light fixtures suitable for mining, light and strong, with an exceptional lighting performance. These luminaires are designed for extreme environments, and can withstand explosions.

Please contact us for more information about Airfal luminaires suitable for the mining industry.

Led lighting for parking lots and car parks

Lighting in parking lots must be functional in order se as to meet with standardssafety. Motorized vehicles walk alongside pedestrians and cyclists in places that are often cramped and difficult to access. The diversity and quality of Airfal’s luminaires make it possible to create lighting that combine safety and luminous efficiency. Due to their long service life and very low power consumption, Airfal’s Led solutions reduce maintenance and energy costs, which represent a significant part of operating expenses for operators.

Choice of luminaires

Motor vehicles emit highly charged dust that is often conductive, and that affects electrical appliances. On the other hand, many modern parks are open to the outside, which brings direct or indirect projections of water on the luminaires.
It is therefore recommended to use waterproof luminaires with IP65 rating.
For luminaires placed in the lower part at low height, the use of grilles with anti-vandal screws is strongly recommended to avoid breakage during shocks with vehicles, or vandalism-related damage.

LED technology

Light Emitting Diodes (LEDs) generate and distribute light differently from HID luminaires. LEDs generate light via a semiconductor, unlike HID lamps, which produce light directly from electricity. In addition, they distribute light using multiple individual LEDs and optics, unlike a single bulb and reflectors inside the unit for HID lamps. Thanks to LED technology, the light is more evenly distributed over the planned surface, while consuming much less energy.

Energy costs

When it comes to energy savings, we need to look at the powers that are usually used for HID lighting compared to LED lighting. For a typical HID lamp, the average power is between 70 and 400 watts. If we look at the same range for a comparable LED light, the power is between 24 and 82 watts.
So, we can see that just by switching to LEDs, there will be a saving of 40% to 60% of energy consumption. From a cost point of view, switching to LEDs will save you about € 300 per device per year in electricity costs. Depending on the size of your facility, this can be a very important saving.
Reducing maintenance costs
In addition to the enormous cost savings associated with energy consumption, LEDs can also save you money by reducing maintenance costs. Due to the way in which LEDs generate light, their lifespan is maximum. Instead of stopping working properly after a while, the light output generated by the LEDs degrades very slowly over time.
As a result, the functional life (often greater than 100,000 hours) of a LED luminaire can be significantly longer than that of a HID lamp. For example, by replacing a conventional 250W HID luminaire with a LED fixture, a typical installation will generate significant savings in maintenance costs.

Lighting performance

Finally, although energy savings and savings in maintenance costs are important, it is imperative that lighting performance is not compromised. Here again, the performance of LEDs is far superior to other forms of lighting. Thanks to a multi-point design, LED lighting applications often provide a more evenly distributed light. This means that the light levels on a given surface will vary less between the mounting locations of the fixtures. HID luminaires, on the other hand, often produce a “point of light” directly below the luminaire, with light levels decreasing considerably as the distance between the luminaires increases.
In addition to a uniform distribution of light, LEDs are available in a range of CCT (Correlated Color Temperatures), and therefore offer a range of options to increase the visual perception of “light”.

What is a lux? How to measure the luminous flux per unit area?

Lux measures illuminance. Its symbol is “lx”.

Practical applications of lux

A Lux number indicates the luminous flux received per unit area. As an example, the human eye operates in a large amplitude of luminous flux:

  • Our full moon night vision is possible from 1 lx
  • During a very sunny summer day, our eyes are subjected to luminous flux of 130,000 lx
  • Our movements require a minimum of 5 lx to be secured
  • We read, write or work easily when the luminous flux is about 150 lx …

To understand this process, it is necessary to consider three concepts: illumination, light (lm) and lux (lx). The first is considered as the luminous flux that affects a certain area; In other words, how much light is coming from a light source on a surface?

To know the answer, we can imagine a lighting process in which a light source emits a certain amount of light; According to the international measurement system, the emitted light flux can be measured from lumens (lm). The higher the number of lm, the higher the illumination intensity provided by the source.

A Lux number indicates the luminous flux received per unit area.

When the light emitted reaches a specific area, the term lux (lx) is used. It is a unit of measurement equivalent to one lumen / m² and with which it is possible to calculate how much lighting affects a given area. However, in order to evaluate the amount of light, it is necessary to take into account aspects such as the dimensions of the space, the height of the luminaire and its distance to the target surface, as well as the photometric data of the lamps and their amount.

It should be noted that if the light source is close to the target area, there will be more lux, but if it is far, there will be less. For example, a luminaire emits two thousand lumens on a surface of one square meter, in this way one will have two thousand lux emitted on this zone, which represents a lot of light. On the other hand, if the same amount of light is used on an area of ​​20 square meters, the illumination of this spot is only 200 lux, ie less light.

To reach a luminous equilibrium, one will be able to use means, techniques and software to calculate it. In addition, the aesthetic and functional aspects should be considered according to the use of each area to be illuminated. The use of luxmeters makes it possible to obtain an optimal level of illumination.

Low temperature lighting and cold storage light fixtures

low temperarature lightingLow temperature and cold storage environments are really challenging regarding lighting. Airfal, manufacturer of industrial and technical lighting, has been developping light fittings to address these challenges, so that you can get enhanced visibility and safety in cold storage environments and in low temperature chain logistics.

Incandescent bulbs, which are scheduled to be discontinued, are not impacted by cold temperatures. However, the light bulbs replacing incandescent bulbs — compact fluorescent lights (CFLs) — are impacted by cold temperature,  though energy efficient.

Exposure to cold temperatures makes it difficult for the common CFLs to heat properly, affecting the level of illumination. Standard compact fluorescent bulbs decrease flux by up to 50 percent at 0 degrees Celsius. For that reason, the lighting industry is including substances in the bulbs, so as to enable compact fluorescent lights to work under temperatures as low as seventeen degrees below zero Celsius. For that reason, compact fluorescent bulbs takes an average warm up time of several minutes to reach full flux.

The TR3 light fixture has been developed for lighting in extreme temperature locations, such as refrigerators, freezers, coolers, and outdoor places in cold weather.

This cold weather light fixture can withstand temperatures of up to –40ºC. The variety of mounting systems allows this light fixture to be installed in places  exposed to very adverse weather conditions such as high winds, snow, heavy rain, etc. This luminaire has a degree of protection of IP 67 offering total protection against dust and against the penetration of water in prolonged immersion.

How to adapt  lighting when growing older

Over time, our eyes become more sensitive and react more strongly to light. It is therefore necessary to do some adjustment in the lighting of the house in order to maintain a good quality of life and sight. Space can become more comfortable even when the signt changes with age.

How does the perception of light change with age?

Changes in vision can occur throughout life, but once you reach a certain age, these changes become even more worrying than simply not seeing objects from a distance. Just like the rest of the body, some muscles of the eye begin to weaken. Have you ever shined a light in one eye and watched the pupil dilate? The muscles involved in this phenomenon are intended to control the quality of the light collected and, as we get older, they find themselves lagging in their reaction time. This implies that the eyes take longer to adapt to dark or bright environments. Other changes may occur such as yellowing of the lens that affects the perception of colors, the appearance of spots or “floating” in the vision caused by particles in the vitreous of the eye and cataracts that cause areas of fog in the eyes. Medical measures may be takento repair these phenomena or improve these conditions, but good lighting may also help to compensate for some of these eye disorders.

What kind of light should be installed to adapt to these changes?

Intense light

The troubled vision due to age can often be solved by simply using more light than usual. This does not necessarily mean that you have to raise the brightness of all the lighting in your home to extreme levels, but you can use bright lights for some tasks, such as table lamps, floor lamps, lighting under cupboards to provide more lighting for activities such as cooking, reading or using the bathroom mirror, etc. That being said, it’s not necessarily a bad idea to increase the general level of lighting in your home.

Ambient lighting

As mentioned above, older eyes have difficulty adjusting to different levels of light as quickly as before. In order to bring as much comfort as possible to the eyes, you need to set up uniform ambient lighting throughout the house. This means that no room should be brighter or darker than another, so there must be smooth transitions from one room to another. The addition of dimmers (dimmers) can also make it easier to adjust light levels in different rooms.

Anti-glare light

The glare of the extremely powerful light emitted by the light bulbs can trigger vision problems and even worse, “eye floaters”. These eye floaters and other eye injuries can cause light scattering in the eye. This increases the sensitivity to glare, which is not the case for low light levels. To avoid glare, make sure your light sources are shaded or not directed directly to the eyes. For example, you can use spots with frosted lenses to hide the light source.

Precision of color

Because the coloring of lenses on the eyes may change, it is important that light sources have a very high CRI or CRI (Color Rendering Index) – usually above 80 – for colors to be more authentic.

Lighting in poultry houses – Chicken farm lighting

Lighting is an essential factor in the success of the commercial production of layers and broilers. The demand for food worldwide is expected to double by 2030. To meet that demand, chicken producers are adopting new approaches to increase production at a reduced cost, with less stress on the environment. Generally speaking, the focus id on enhancing traditional inputs such as water, air, nutrients, and housing, however lighting would deserve more interest.

Light is an important aspect of an animals environment. Avian species respond to light energy in a variety of ways, including growth and reproductive performance. The value of regulating the exposition to light of poultry and livestock to stimulate reproduction has been recognized for many years and is used regularly by commercial poultry and farmers.

Many poultry producers still utilize old residential and commercial incandescent lamps in their barns. These lamps are not the best suited for poultries. Indeed, iincandescent light is not the same as sunlight, and the best light for humans is not necessarily the best light for animals.
Animals used to live under the sunlight, whose spectrum differs substantially from that of incandescent light. Sunlight is a combination of all colors. Modernfarm lighting system should attempt to mimic the sun’s spectrum. Read more

Tips for buying LED bulbs

First of all, there is no real comparison between LED bulbs and other conventional light bulbs (halogen, incandescent, compact fluo and others).

Indeed, it should be noted that not all LEDs have the same lighting power and that some of them alone can have a luminous flux equivalent to more than 500 LEDs less powerful.

The most efficient and economical light bulbs are now the LEDs, but they are not bought like a conventional incandescent bulb or even halogen. Here are some of our tips for making the right choice.

With incandescent bulbs and halogens, we speak had to deal with watts (W), since their luminous intensity depends on their power consumption. This is no longer the case with LEDs. For example, a 6W high performance LED illuminates as well as a 60W incandescent bulb or 46W halogen. The central LED information is the lumens (lm). Read more

Led replacement bulbs: potential technical and electrical risks in lighting

Replacement  LED lamps (only the lamps that are replaced and installed in the already existing luminaire) have been available on the market for some time. However, there are  potential technical and electrical risks associated with this type of substitution lamps. This type of renovation can also lead to an increase in light nuisance and discomfort to users if the necessary conditions are not met.

Note: these article deals with  functional public lighting intended to ensure the safety of the users’ travel for all types of traffic (pedestrians, cyclists, motorized vehicles) and irrespective of the duration of illumination chosen. Some ambient lighting fixtures (outdoor lighting fixtures without required photometric performances for example) are not affected.


Between 2012 and 2017, almost 80% of public lighting lamps in Europe should have been replaced according to European regulations. In Europe, many of the luminaires in service are over 25 years old and therefore present an urgency for renovation (with some  mercury vapor lamps, mostly concentrated in rural municipalities).  within the framework of the law of energy transition and the fight against light nuisance. A large number of  luminaires are still equipped with discharge lamps (SHP – metal halide) with less than 15 years of installation.

An investment not necessarily profitable

If these replacementLED lamps are cheaper to purchase, the investment expenditure , even lower, may not be amortized due to unsatisfactory performance and reliability guarantees for the safety of the users. Electrical safety, malfunctions and consequent maintenance are also questioned.

On the other hand, the guarantee of the equipment could no longer be assured by the manufacturer of the luminaire. Consequently, any breakdowns resulting from the substitution are no longer part of this guarantee and will represent an additional cost for the communities

IP protection classes: the different degrees of protection in lighting

On many occasions, lighting fixtures must stand rough conditions and work for their intended period of time nevertheless they are set out to dirt, dust and humidity. Ingress of liquid and/or solid particles into lighting equipment can not only be harmful to the equipment, it can be dangerous to the operator. Therefore when buying industrial lighting fixtures, it is essential to know what degree of “ingress protection“, also called IP class, or IP rating the product offers. IP codes stands for “ ”  and sometimes also for “International Protection Rating” IP protection classes define how and where the lights can be used without any safety risk.

The protection rating indicates also the protection for people against potential dangers when using the equipment. With regard to suitability for various environments, the systems are divided into relevant IP codes).

 These IP ratings specify the following:

  1. Protection of persons.
  2. Protection of light fixtures (and electrical equipment) against the penetration of solid matter, including dust.
  3. Protection of light fixtures against the harmful effects of water

Explanation of IP Codes

ip protection class

An IP code consists of the letters “IP” and two digits. The first digit is 0…6 and the second 0…9.

Outdoor lighting for parks and public gardens

Lighting of parks and gardens should focus on the safety of pedestrians walking on the trails through the park. Lighting must allow pedestrians to discern obstacles or other hazard , and give them the opportunity to see other pedestrians. Waterproof light fixtures shall be used for such purpose.

Light sources
Parks and gardens generally require white light in order to obtain a better color rendering. The white light provides improved visibility for pedestrians. Therefore, metal halide lamps with ceramic arc tube or the white LEDs are great options.

Recommended level of lighting for a park
Lighting in park areas shall meet recommended levels, and also minimize light pollution and intrusion on neighboring properties. The lighting level can significantly impact on the appearance and safety of the park at night. The high-pressure sodium lamps, a commonly used source for urban light, cast a yellow-orange light that gives poor color rendering; this light challenges the visual clarity and considerably impairs the overall quality of the night urban environment. In contrast, metal halide lamps diffuses a soft white light that makes colors more accurate; they provide better visual clarity, and require less power for the same perceived visibility. The light quality is also influenced by the amount of light – or more precisely, by the relationship between the brightness of light and the distance to the light source. The light becomes more diffused as we are farther from the source, so that for a given brightness, there are heights where we should place the light source to create the desired light quality.

Waterproofing and impact luminaire protection


Waterproofing  and impact luminaire protection

 When you open a catalogue of luminaires, we are accustomed to seeing nomenclatures and symbols that perhaps sometimes we don’t know how to interpret. Two of those parameters that more defines a luminaire are the IK e IP of the fixtures. But, what do they really mean? Do we know how to interpret it? In the following lines we will define these parameters that will help us choose which luminaire fits better our installation and its environment.


IP code

IP code indicates the degree of protection against penetration of solids inside the enclosure and against the penetration of water. This code shows its impermeability and their insulation from the environment, as well as ease of access by persons inside the luminaire. This code is composed of the letters IP and two digits.

Recommended light levels in the industry

Good lighting combines three aspects: high luminous efficiency, long life and good color rendering.


The lighting of industrial premises should:

  • Facilitate the Execution of a Task: the Visual Performance Concept.

Normal vision can only be exercised with minimum light. A good level of lighting allows for a good productivity, which means fewer errors or accidents, and reduced eyestrain.

  • Ensure Well-Being: the Fundamental Concept of Visual Comfort.

In addition to the required level of illumination, it is also essential to ensure the following:

  • A good quality of the light emitted by the sources
  • The uniformity of the illumination
  • The adequate balance of illumination to avoid glare in particular.

Illuminating the industry work areas

The illumination level has to be adapted to the nature and the precision of the work that needs to be performed. To illuminate the work area, it is reccommended to use local lighting, adapted to complement the general lighting of the premises.

  • For inland circulation: 40 Lux Minimum Illumination
  • For changing rooms and bathrooms: 120 Lux Minimum Illumination
  • For blind premises assigned to permanent work: 200 Lux Minimum Illumination

Lighting for Outdoor Spaces:

  • For taxiways: 10 Lux Minimum Illumination
  • For outdoor areas assigned to permanent work: 40 Lux Minimum Illumination

Lighting for Specific Work Areas:

  • For average mechanics and office-based typing work: 200 Lux Minimum Illumination
  • For machine processing and office-based drawing work: 300 Lux Minimum Illumination
  • For fine mechanics, engraving, drawing and color comparison: 400 Lux Minimum Illumination
  • For precision engineering, fine electronics and various controls: 600 Lux Minimum Illumination

 The level of illumination required in the industry depends on:

  • The size of the details that need to be observed
  • The contrast between the object / form and the bottom (the greater the contrast, the higher illuminance is required).

The Following Aspects Must Also Be Considered :

The speed of the work execution

  • The movement of the monitored objects (the faster the movement, the higher illumination is required)
  • The age of the operators

In industries which require fine and precised mechanical tasks, as well as the electronics industry, specific lighting reinforcements on the workstations must be installed. Some industrial sectors, the chemical sector in particular, require the use of protected luminaires.

Industries in which color rendering is extremely important, such as the printing industry, require the use of appropriate lighting lamps. In other industries such as paint manufactoring, plastics or resins, the industrial process requires the use of special UV types or IR light emissions.

Lighting parks and gardens with Led lights

86A lighting project focusing on illuminating parks and public gardens should consider three main aspects:

  1. It must be based on an efficient energy consumption
  2. It must present a minimal environmental impact
  3. It must achieve a good quality / price investment.

Therefore, designing a good lighting for a park or garden must combine efficiency and saving with and security and comfort. Always consider an adequate lighting for all parks and gardens, as they are dynamic and living spaces, a lighting which must adapt properly to different seasons, luminosities and circumstances.

When the night falls, the chromaticism and clarity of the park are the main factors that influence the influx of people. The distribution of light, its intensity and its impact on the surrounding elements play an important role in whether people will use the park or not. Read more

6 Reasons why you should upgrade to LED industrial lighting

A high quality industrial led lighting system will significantly improve operating costs of your company, as well as working conditions, and provide added safety. We highlight in this article some of the reasons why you should consider upgrading your industrial lighting system to LED, if you haven’t already.industrial led lighting

Industrial LED Lights are longer lasting
LED light bulbs tend to last up to 25 times longer than traditional industrial light bulbs. . One of the amazing advantages of installing LEDs is their long operating life. . Unlike other industrial lighting technologies, LEDs don’t burn-out, but they gradually fade over time. Some industrial LED light fixtures have very long operating life, with a lifespan of more than 80,000 hours.
Improved energy efficiency with industrial LED Light fixtures
LED lights usually cost more to install initially. However, those costs can be reduced due to their longer lifespan, and overall electricity usage. It is generally agreed that LED bulbs tend to use around 75 percent less energy than other types of bulbs.

Higher light quality thanks to led light fixtures

Improvements in lighting technology for led bulbs have increased lighting efficiency, as well as color quality. Improved lighting quality can affect worker performance and accuracy in a variety of activities. A new lighting installation can have a marked improvement on employee output in industrial installations.

LED lights produce less heat

Halogen and incandescent bulbs produce a lot of heat. If there are combustible materials near the industrial light fixtures, then this added heat can be dangerous and increase the fire risk in your industrial facility. This also results higher energy spending since more air conditioned is needed.

Improved safety

By installing led light fixtures in industrial environments, we can improve safety in industrial areas, such as warehouses and manufacturing facilities. A new LED installation also offer higher brightness that reduce the number of LEDs required for a fixture while improving worker safety. Brighter lighting on the shop floor can lead to fewer safety problems, while improving worker output.

Maintenance of the industrial lighting installation
Regular maintenance used to be vital to ensure that industrial facilities received the desired quantity and quality of light, with traditional lighting systems. Periodic maintenance used to produce a range of benefits, including a brighter workplace, a higher level of security in the industrial facility, and enhanced productivity. Airfal industrial LED fixtures are nearly maintenance-free, which results in less time and less expenses spent in replacing light bulbs. Operational downtime is also avoided, since LED bulbs have a longer time span .

LED lights for industrial facilities are more sustainable
Green lighting is a key trend, also in lighting environments. If your company is looking to “go green”, then installing LED light fixtures into your factory on warehouse can be very effective. Becoming more sustainable can help to improve your company image, as well as reduce operating costs. LED light fixtures are more sustainable as they use less energy, and they require less overall maintenance.

Why you need to rethink the lighting of your factory or warehouse

led lighting energy savingenergy saving lightingSome simple steps will make the lighting of a factory or warehouse energy efficient, which can lead to greater profits

Most often inefficient use of lighting in factories and warehouses causes wastage and losses. This wastage can be measured and reduced by taking adequate steps, starting with the audit of the electrical installation. With an energy audit, we can identify the possible areas of wastage like inefficient and excess use of lights. By taking appropriate measures, energy can be used more efficiently to light up a factory or a warehouse.

Every factoryor warehouse has savings to uncover that can be as simple as changing a light fixture, or using Led light bulbs. The return of investment of LED lighting can be easily calculated, and the payback is usually significant. The counter argument has always been that it is a big expense to install LED lighting, but if you are replacing a traditional light fixture with a LED version, the numbers speak by themselves.

It is worth committing to an energy efficiency change in a factory or warehouse. Changing to new light fixtures will have the following positive impacts:

Upgrading lighting is one of the easiest way to lower energy costs. When replacing a light bulb, burning fewer watts per unit of light generated, and producing less heat in hotter months of the year, can result in savings of up to 75-80%.

The challenge can be the upfront investment, but the average LED bulb will last 10 to 25 times longer than a traditional light. With up to 80000 hour lifespan, there is no need to hire expensive access equipment to change lamps and bulbs located in áreas that are of difficult Access in the Factory or in the warehouse.

New light fixtures provide more powerful ways to control your light spending. Wireless technology has made the ability to control lighting easier than ever. LED light fixtures can be connected to a network that controls the lighting in your plant or warehouse via a software, from a computer, a smartphone or a controller itself. Wireless technology helps to control every aspect of lighting in the plant or warehouse, from hue to intensity, resulting in a more productive work environment.

With 100% instant light, you can eliminate the “start up” or “cool down” times of old factory lights

Electronic ballasts are useful too. Electronic ballasts are twice as expensive as conventional magnetic ballast but the energy consumption is about 25%. Conventional magnetic ballast takes about 8 to 10 watts whereas electronic ballast takes about 2 watt per 40 W tube. The payback period of an electronic ballast is about 2 years. Although the initial cost is higher, the lifetime savings are significant.

Industries where lumen requirement is very high should use Energy Efficient Lights fixtures. By improving light quality in your factory warehouse, you can make it much easier to carry out tasks, which affect positively your financial results.

Energy saving lighting for manufacturing or assembly plants, and warehouses will definitely give you a competitive edge.

Recommended lighting  levels for offices

Light Level or Illuminance, is the total luminous flux reaching  on a surface, per unit area.  Lighting systems in offices  are usually  designed based on the light levels or illuminance required by the tasks performed within each working area .

Office spaces are often over-lit as a result of using outdated lighting fixtures. These older lighting systems were  designed to accommodate paper-based reading tasks , that usually needs  light levels of 500 to 750 lux. Today’s work at the office  primarily involve computer based tasks, and the lighting levels can range from 300 to 500 lux.

We should bear in mind that having the  right lighting requirements onto a task area such as a desk is only one of the elements that has to be considered in the overall lighting project. Indeed,  the whole working environment should be taken into  consideration: the impact of lighting  onto the walls,  and across the space has also to  be considered, so as to create a pleasing and productive working atmosphere. It is recommended to avoid  any sharp  change in light levels within an office space as this will cause the eyes to have to continually adjust, resulting in eye  fatigue, and affecting negatively the productivity of workers.

What is the recommended lighting level for offices?

The below  table represent light level recommendations for office areas.

Areas and activities Intensity Recommended Lux 
Accounting office High 500 – 750
Office in general Medium 250 – 500
Waiting room Low 150 – 400
Reception desk Low – Medium 300
Computer work station Low – Medium 300 – 500
Meeting room Medium 500
Technical drawing High 750

Atex lighting for fluorescent lights

vitraIndustrial lighting must sometimes provide illumination in areas where usual lighting is inadequate due to the risk of accidental ignitions of flammable or explosive of materials. Airfal range of products include fluorescent light fixtures, that are suitable for Zone 1 and Zone 2 lighting installations with ATEX certification.

A high risk or hazardous area is where a mixture of air and potentially explosive substances such as gases, vapours, mists or dusts, could spread. Typical examples of hazardous environments are refineries, drilling platforms, chemical and power-generation facilities, mines… In these locations, it is required to ensure safety against occurrence of sparks and excessive temperature or arcs with adequate light fixtures. Currently, lighting for such areas requires complying with standards classified as Zone 1 and Zone 2.
Zone-1 contains a hazardous gas/air mixture under normal operating conditions. Zone-2 is hazardous only in abnormal operating conditions, and if so, it will only exist for a short time.

Our Explosion Protected Lighting For Hazardous Locations include fluorescent light fixtures that have been developed for use in hazardous areas and harsh environments and are certified. These fluorescent light fittings are manufactured with the highest quality materials and finishes.

Lighting for the industrial sector

Well balanced levels of illumination are essential in establishing safe and productive working conditions. Companies should take into account lighting in the industrial work place very seriously. Optimizing industrial lighting requires consideration of work tasks, environmental conditions and economic considerations. The benefits of adequate lighting include greater productivity and accuracy, improved safety and security, and improved moral for workers.

Several factors will have to be carefully analyzed such as the task, the working environment, the quantity and the quality of lighting. Well balanced illumination is essential for the establishment of a safe and productive work environment; optimizing illumination in the industrial workplace requires a number of considerations including level of lighting, type of equipment, environmental aspects, financial requirements, optic, lamp, temperature, goals, or type of work….

Lighting in the Industrial sector can be quite complexe. Due to a wide range of operations and tasks, many aspects have to take into consideration as they will impact the amount of light reaching a work surface as well as its quality.

 Required level of lighting in the industry

The required quantity of light (illuminance) depends mostly on the visible task the worker, or the type of the industrial task performed.

Here are some examples of industrial recommended lighting levels:

General Engineering Rough work

160 lux

General Engineering Medium work

400 lux

General Engineering Fine work

800 lux

General Engineering Very fine work

1600 lux

Outdoor Areas Mechanical loading

10 lux

Outdoor Areas Manual loading

50 lux

Warehousing Inactive storage

20 lux

Warehousing Loading bays

100 lux

Warehousing Small storage, packing

200 lux

Quality of lighting in the industrial sector

Factors influencing the quality of industrial lighting have a significant impact. These factors include flicker and glare, degree of contrast or shadows. There should be good contrast between objects of interest and background. Greater lighting in areas next to but outside the immediate work environment can make visibility difficult.

 Industrial lighting requirements

Industrial Lighting Standards address the importance of evaluation of energy consumption, and other key features aimed at improving overall performance in the workplace.

2015: International Year of Light and Light-Based Technologies


On december 20th, 2013, the United Nations General Assembly declared  that 2015 will be the International Year of Light and Light-Based Technologies (IYL 2015) .

Focused on the science of lighting and its applications, the International Year of the Light 2015 is a worldwide event that will stress the importance of light and optical technologies for the development of society.

This International Year is backed by a large consortium of scientific organizations including the UNESCO. It brings together many international players such as associations and scientific institutions, educational organizations, technology platforms, non-profit organizations and private sector partners.

With this event, the United Nations has recognized the importance of raising global awareness of how light-based technologies promote sustainable development and provide solutions to global challenges in energy, education, agriculture and health.

Light is a universal resource

According to the organizers of this global event, “Light plays an essential role in our daily lives and is located at the crossroads of many scientific disciplines in the 21st century. It revolutionized medicine, allowed the development of international communications via the Internet, and continues to influence many cultural, economic and global society policies. For centuries, the light has transcended all boundaries including geographic, gender, age, culture and race, and remains a tremendous resource to inspire training and research. »

Throughout this International Year of Light will be organized around the world at regional, national and international events, events, conferences, seminars, exhibitions and shows around the light, with among others the desire to promote technologies based on light and ensuring sustainable development.

Certifications of products for use in hazardous locations

Until recently, a manufacturer of electrical products for hazardous locations would have to design equipment to meet the national standards of each country in which he wanted to sell its products. Today, a manufacturer can go to almost any Certification Agency and receive a Certification Mark which will be accepted in almost any country in the world. However there are still differences between certifications. For instance, ATEX is a regional scheme in the European Union, and is mandatory. IECEx is a global certification, is voluntary and is open to all countries.

Equipment for use in hazardous locations must be certified to an appropriate national standard and marked as such by an accredited third party testing organization. There are currently 3 different certifications of products used in hazardous locations

North American Certification

The equivalent of the ATEX directive in the US is the HAZLOC standard. This standard given by the Occupational Safety and Health Administration defines and classifies hazardous locations such as explosive atmospheres. It aims to control the risks related to explosion in certain environments.
It comprises two elements:
– testing and evaluation of products being used
– inspection of the factory

In North America, all electrical equipment must be approved/certified as follows:
• In the USA, by a Nationally Recognized Testing Laboratory (NRTL) accredited by OSHA.
• In Canada, by a Certification Body accredited by the Standards Council of Canada (SCC).
• The proof of certification must be displayed on the equipment in the form of the mark or label of the certification body.A certificate/declaration of compliance is not sufficient.

The Certification Body that granted the certification must inspect each factory (defined as the location where the product is manufactured and labelled) four times per year. This is the same for every Certification Body, and each must perform their own inspections. This is significantly different from ATEX and IECEx, certifications where a manufacturer may have Certificates issued by a number of different Notified Bodies, but the audit is only performed by one.
In North America, hazardous locations have traditionally been defined by a combination of classes and divisions .

In the U.S. and Canada, the certification of hazardous locations electrical equipment is cnow hanging and is evolving to the zone system. There is now an international 3-Zone area classification system for equipment used in hazardous locations.
• Zone 0 – An place in which an explosive gas atmosphere is continuously present
• Zone 1 – A place in which an explosive atmosphere is likely to occur in normal operation
• Zone 2 – A place which an explosive gas atmosphere does not normally exist.
In Canada, all new installations must use the 3-Zone system. Existing installations may continue to use the 2-Division system or opt to re-classify using the 3-Zone system.
In the U.S., all installations (both new and existing) can either continue using the 2-Division system or re-classify their product using the 3-Zone system. Read more

LED lighting fixtures for use in hazardous areas

US system compared to EU Atex ZonesAt the same time that Lima Climate Change Conference is about to start, manufacturers have become increasingly aware of the urgent need to implement more environmentally friendly solutions for the planet. Lighting represents almost 20% of global energy consumption and industrial locations that operate 7 days a week and 24 hours a day consume a great deal of energy to ensure their lighting. To cope with these challenges, LED technology is now gaining widespread use in industrial lighting, as it is especially suitable for use in hazardous locations.
A high risk or hazardous area is where a mixture of air and potentially explosive substances such as gases, vapours, mists or dusts, could spread. Typical examples of hazardous environments are refineries, drilling platforms, chemical and power-generation facilities, mines… In these locations, it is required to ensure safety against occurrence of arcs, sparks and excessive temperature. Currently, lighting for shale gas drilling platforms that are expanding in many countries, requires compliance with a gas facility classified as Zone 1 (ATEX hazardous area) and Zone 2 (standards Class I Div 1 and Class I Div 2 in the USA).
LEDs are full-spectrum light sources and provide excellent color rendering. LED directs the light to where it’s needed with very little scattering or loss. By contrast, conventional lamps cast light in every direction hence the reduction in lumens compared to LEDs. Not only LED lights meet the highest standards of color rendering IRC (70-85), efficiency (up to 160 lumens/watt) and lifetime, but in addition, unlike other sources such as fluorescent tubes, their emissivity is increased in cold environments.
Compared with sodium vapor lamps under high pressure to mercury vapor lamps or incandescent lamps, LED can prevent accidents related to poor visibility thanks to its better color rendering. LED lighting also facilitates better reading of safety instructions for earlier intervention in cases of immediate danger. This helps to lower the risks of accidents and allow faster interventions.
Intelligent lighting control can furthermore provide lighting as needed: LED lighting offers another advantage of being able to vary the light intensity as needed without loss. Coupled to sensors, LED lighting can adapt and increase or decrease the brightness depending on the presence of certain gases, some dust or in case of fire. In addition, a centralized management is now possible to optimize energy savings.
High ceilings in industrial facilities make that the light fixtures can be remote or difficult to access. Maintenance and replacement could be extremely expensive. Sturdy and long running, LED lighting requires very little maintenance, which is essential, due to the vast expense of a shutdown. Containing no gas, LED lights are very safe and recycling is easier, like any other electronic product. With 100,000 hours of life, LED lighting reduces the need for maintenance. Even coupled with an intelligent lighting system, it only lights up when needed and it turns off automatically.
In hazardous areas such as drilling platforms lighting also has to be able to withstand constant shock and vibration. ATEX certified lighting should be stronger than traditional lighting. With a 100% electronic lighting, LED is already more resistant than other materials.
Airfal develops ATEX certified LED lighting solutions (Pyros, Vitra and Secure) that reduce energy consumption without compromising the level of lighting, especially in hazardous locations. Resistant to shock and vibration, they avoid the frequent replacement of lamps. They don’t contain mercury or other hazardous products to make them more ecological. Airfal LED light fixtures are environmentally friendly and offer energy efficiency and light control for difficult and harsh locations.
