Study reveals how light affects the well-being of patients in hospitals

lighting hospitalsA group of researchers at the Cleveland Clinic in the USA the has shown that there is a correlation between levels of exposure to light during the day and the psychological state, level of fatigue, and even pain of patients. The study suggests that patients in a normal hospital room, are sometimes exposed to too little light during the day and can not find a normal sleep-wake cycle. Other studies show that winter depression (SAD) is related in some countries to the lack of daylight during certain months of the year, during the fall or winter.

 Impact of lighting in hospitalized patients

To assess whether the light could play a role in healing inpatient, Esther Bernhofer, lead author of the study, and her colleagues collected data from 40 men and women hospitalized between May 2011 and April 2012. Patients wore a wrist device for 72 hours to measure their state (standby or asleep), and the level of exposure to light. These patients completed questionnaires to assess their psychological state, and the level of pain they felt. In general, the patients analyzed slept little, with frequent sleep interruptions, and an average of only four hours of sleep per night. Patients who were less exposed to the light during the day were generally more depressed and more tired than those who were exposed to a higher level of lighting.

 A minimum of 1500 lux during 15 minutes a day

On average, patients in the study were exposed to only 105 lux during the day. As a comparison, the average office lighting provides approximately 500 lux, and a sunny day can provide up to 100,000 lux. Previous studies have shown that a minimum of 1500 lux was necessary to establish a normal sleep-wake cycle, but it was better to be exposed to at least 4000 lux over eight hours, according to professor Bernhofer.

“So far, no one has analyzed the relationship between lighting and states such as sleep, mood and pain in the hospital,” said professor Bernhofer. ”

According to the authors, this study provides a basis to improve lighting in hospitals in order to favor cycles of sleep and wakefulness in patients, improving mood of patients and helping them to reduce pain in hospitalized adults. However, this study is only a preliminary basis, and should not be considered sufficient to change the lighting strategies in hospitals. It provides insight so as to improve the overall patient experience at the hospital, and try to accelerate the healing process.

How to assess the quality of lighting installations in the workplace

Lighting in the workplace is a key environmental factor for employees: we need to set up an appropriate work environment. Different levels of lighting are required for different types of work – close, accurate work such as soldering a control panel will require higher light levels than a waiting room.

Many laws and standards regulate lighting in the workplace. Units of measures are typically used by professionals to assess the quality of  lighting in the workplace.

Here is an overview:

Luminous fluxThis is the amount of energy emitted by a source in the form of visible light in the entire space per unit time.FLumen lm
Light intensityAmount of radiated light emitted in a given point source direction.ICandela(Cd)
LuminanceLuminance is a photometric measure of the luminous intensity per unit area of light travelling in a given direction. It describes the amount of light that passes through or is emitted from a particular area, and falls within a given solid angle. Measures the light intensity collected in a direction and at a point of the light reflected from an illuminated surface. L’appareil de mesure s’appelle un luminancemètre.Lcd / m2(Candela per m2)


IlluminanceIilluminance is the total luminous flux incident on a surface, per unit area.The instrument is called a lux meter. This is an important unit of measur for the standards of comfort and safety.ELux (lx)
Luminous efficiencyThe luminous efficiency of a system depends not only on the source, but also on the accessoriesof the light fixture (reflectors, light distribution grid, transparent protection).Lm / WLumen / Watt
Color temperatureThe color temperature is used to determine the temperature (actual or “virtual”) of a light source, from its color.KKelvin
LifetimeThis feature is important when the cost of replacing the bulbs is expensive (if it is difficult to change the bulbs, for example in the case of high ceilings). Hr

Lighting for high ceilings

High ceilings can be a challenge when incorporating lighting applications. When dealing with high bay lighting, we will have to face many challenges, such as minimizing contrast, reducing glare, or meeting strict safety and hazardous environment requirements. Low maintenance, energy saving light fixtures, designed to drive down costs are also needed. High bay lighting generally applies to libraries, atriums, gymnasiums, cafeterias, but also warehouse spaces, and high bay workshops.

T-5 fluorescent lighting is often used for lighting in high ceiling areas, meeting the recommended light levels and increasing the quality of light. Until very recently, LED technology was not an option due to high prices. However, high-bay LED fixings are now available, providing good quality of light at reasonable price, with paybacks from energy savings. Employees and customers now feel better in their working environment, meeting safety standards at a competitive cost.

An infographic analyzes the overall energy efficiency of LED bulbs

An infographic by Chadwicks analyzes the overall energy efficiency of LED bulbs, from manufacturing to the end of its useful life.

The infographic compares compact fluorescent lamps, incandescent lamps, and LEDs. The infographic analyzes different items such as lifespan, energy consumption during use, the energy used to manufacture …

According to the infographic, if a LED lamp requires 9.9Kwh to be made, compared to an incandescent lamp that needs 0.612Kwh, the LED bulb spends much less energy, which leads to greater profitability.

While LED bulbs are more expensive, they have a longer life (between 50 and 100,000 hours for LED lamps, versus 1,000 hours for an Incandescent light bulb). Another advantage is that LED bulbs have to be changed less frequently than incandescent lamps.


Lighting for greenhouses and grow lights

greenhouseThe LEDs have long been recognized for their many advantages over traditional light fixtures. Their long life span, energy efficiency and flexibility have made possible using LED lighting for a variety of applications. LED lighting is now commonly used in the agricultural sector.

Plants respond to the intensity and quality of light. Artificial lighting is frequently used to control plant growth under various conditions. Plants differ in the need for light, and most plants will grow in either natural or artificial light.
If the light is an obvious need for plant growth, it is also one of the least understood for greenhouse cultivation factors. In addition, lighting is often considered less important than the nutrition of plants. However, it is important to supplement natural day light in greenhouses. Many traditional lighting technologies can not be used because they result in excess heat, which can be harmful to plants. Photosynthesis is the use of light energy to decompose water and to transfer hydrogen from it to carbon dioxide in the presence of chlorophyll. For plants to grow well in a greenhouse, there should be a temperature and a light adapted to the plant. These conditions should allow optimal absorption of chlorophyll, essential for photosynthesis and plant growth. In recent years, research has shown that the plants are more sensitive to some particular wavelengths of light. Indeed, absorption of chlorophyll photosynthesis is increased when the plants are exposed to red light (640-660 nm) and blue (450 nm). These studies showed that the absorption peaks of the chlorophyll are within the ranges of 400 to 500 nm and from 600 to 700 nm. Read more

Lighting of car maintenance pits and car garages

lighting car workshop Car maintenance pits, in car workshops, are located below the ground level, and they are used for vehicle repair. The work carried out in the pits involves the use of highly corrosive chemicals such as brake fluids , detergents , fats … As car maintenance pits are under the ground level, there are additional risks such as fires, explosions, poisoning related to vehicle exhaust , the fall of a person in the pit ….

To secure a car maintenance pit, any sources of ignition should be removed, as explosive vapors tend to accumulate at the bottom of the pit. When working in the car workshop, we shall make sure that all the electrical and lighting installations must be explosion and flameproof. A lighting level of 550 lux is sufficient to work safely. Ventilation shall also be efficient. In addition, luminaires used must be resistant to shocks that may be caused by falling metal parts.

For this reason, it is necessary to use luminaires perfectly suited to this environment. The Secure waterproof light fixture, created by Airfal, has an IP68 protection. It offers a comprehensive level of protection against dust and against infiltrations. This light fixture is also IK -10, which is the highest level of protection against shock applicable to luminaires. It was specifically designed for ATEX zones 2 and 22 , and is therefore suitable for installation in locations where there are explosive gases or dust . This luminaire is perfectly suitable for lighting of repair and inspection areas of vehicles in garages and car workshops.

Waterproof led lighting by Airfal applied to urban furniture



The Aranzadi Park is an area of ​​Pamplona in the north of the cit , between the neodighboods Chantrea and Rochapea . Throughout the centuries it has been a dedicated space with green gardens and recreational areas.

This metropolitan area is the second largest of Pamplona .
Some of the plots have been maintained for horticultural use , and other spaces of the forest to the river , keeping their traces and the value of its fruitful soil .

In order not to interfere with the landscape of the park, the architects wanted to use unique street furniture . In the words of the architect and director of works Aranzadi Jesus Arcos, furniture has to have “ simple and pure lines .” “You have to keep in mind what Aranzadi was, and we did not want to have furniture that broke with that environment ,” he said . Some of the banks use are illuminated by four tubular watertight polycarbonate luminaires with LED lighting. The fixtures are made ​​by Airfal International . ”
The illumination with led occupies less space, provides more strength and consumes less , “says Jesus Arcos. The architect notes that this type of lighting was previously installed indoors but this is the first time it is placed in a park , outside , with exclusively designed furniture para the Aranzadi park . Further, he stresses that this design avoids installing more furniture items, as streetlights. Similarly, the same elements that make up the gateway end up being used as picnic .
“It’s an area where many trees have been planted . The result will be like a line of light that is introduced in the forest with trees on both sides , “concludes Jesus Arcos.
The luminaire design had to meet the demanding needs of the project and for this, they used a combination of several models in the catalog of Airfal : Waled , TR1 and Tunnel, and several innovations to get a light with tube opal and IP68, with special reflectors that could be integrated into the urban furniture specially designed for Aranzadi Meander Park .

How lighting could affect our emotions and behaviour

120Neuroscience researchers have been investigating the influence of light intensity and color temperature on human’s mood and behaviour.

The lack of light is usually thought to affect the mood: it can lead to the condition known as seasonal affective disorder, or winter depression. However, recent studies by North American researchers show that both positive and negative emotions may be intensified by brighter lighting, while lower lighting may dampen those moods. Contrary to popular belief these researches show that depression-prone people actually become more depressed on sunny days.

Other similar correlation measures the effects of different colors of light on human’s mood and behaviour and how these can affect the body in different ways. Read more

Surface mounted luminaires

superdeltaAirfal is continuously trying to create better, more efficient lamps and luminaires that balance energy consumption to quality of light.

Often there is insufficient space in the ceiling to install conventional suspended luminaires,  which leads to the use of surface mounted light fixtures:  that way, the lighting installation can be adapted to any  given situation. In addition, using surface-mounted light fittings considerably reduces the level of installation work in solid ceilings or existing buildings. The lighting installation can be easily adjusted to suit any given situation.

Surface mounted luminaires can be installed directly beneath the ceiling to create the level of lighting required for perfect working conditions. The flexible positioning of the surface mounted luminaires makes it possible to adjust the space and lighting requirements.

Airfal has a large range of surface lighting luminaires, perfectly adapted to lighting in industrial areas, offices, universities, hospitals… Well balanced luminance levels contribute to create a more cheerful and productive  atmosphere. These luminaires are a combination of cutting-edge technology, functional brilliance and aesthetic appeal.

Here are some of the surface mounted luminaires of the Airfal range:

Superdelta: an industrial luminaire with a decorative touch. Possibility of making continuous lines with the accessories, rails, etc. existing for the Delta model. Its main applications are in schools and shopping centres.

Metalic: With pre-lacquered steel plate body and gloss aluminium reflector or optionally pre-lacquered steel plate reflector included, it is distinguished by its aluminium slat, making it the perfect luminaire for schools and places with UGR (Unified Glare Rating) demands.

Deco: an innovative and economic option for lighting offices, shopping centres, etc. With a pre-lacquered steel plate body, it includes a gloss aluminium reflector and optionally a pre-lacquered steel plate reflector.

Lighting of the new San Mames stadium by Airfal

san mam

The first stone was laid on 26 May 2010 and the construction of the new stadium officially began on June 25 th,  the same year . The construction of the stadium took place in two stages: the first one, already completed, implied the construction of the two sides , the last step being the VIP lounges. It is estimated that the stadium will be fully completed in spring 2015, however the soccer team is already playing home games in the new stadium.

Lighting was regarded as a key element for the façade. Semi- transparent and waterproof luminaires were chosen for security reasons, such as the evacuation of the stadium for example.

White tone metal elements covering the stage helped to improve the visual aspect of the stadium, and to define its identity. At night, when there is no sporting event , the facade is illuminated and is  a true landmark in the city light . During the matches , it is the stadium interior lighting that take over.

Most lights used inside the stadium have been specially designed for Als Lighting, the company in charge of lighting, and manufactured by Airfal International. The architect is Cesar Azcárate , business ACXT – from  Idom .

Among the models used, not specifically designed for this stadium, there are two tubular polycarbonate fixtures, which are low consumption and high resistance to IP67 IK08 , and adapted to the lighting requirements of the entire project.

Light level recommendations in the industry and retail

Following our previous post, we enclose a guide to the recommended light level for different industrial and commercial activites:
Chemical activities; Transport industries such as train stations, gas stations, car garages, naval docks; Offices and administrations, Shops, merchandise shelves, small shops….

This guide gives the recommended minimum lighting levels for different types of work activities

Lighting should be sufficient to enable people to work, use facilities and move from place to place safely and without experiencing eye-strain.
If people have difficulty doing their job because lighting is too low then setps should be taken to improve it. However, if an area measured falls outside these levels, it does not necessarily mean that the whole lighting system needs to be modified. Other measures such as task-specific lighting might be more appropriate. Generally speaking, the finer the detail, the higher the light level required.

Outdoor light level is approximated at 10,000 lux on a clear day. In enclosed areas like commercial buildings, the light level may be as low as 25 – 50 lux. Additional lighting equipment is often necessary to compensate these low levels of lighting.

optimum level lighting

Recommended light levels for common types of working activities

A minimum level of illumination is required to read correctly and without fatigue objects and thus perform correctly (and sometimes safely) the intended task .
The level of illumination required depends on the activity to perform
Light Level or Illuminance, is the total luminous flux incident on a surface, per unit area. Usually, standards and norms define the light levels by task. The difficulty is to define the space in which the task is to be performed. The amount of light being given off by a particular source, in all directions, is called luminous flux (or “luminous power” or “lux”) and is a measure of the total perceived power of light. It is measured in lumens.
Measuring Units Light Level – illuminance
Illuminance is measured in foot candles (ftcd, fc, fcd) (or lux in the metric SI system). A foot candle is actually one lumen of light density per square foot,one lux is one lumen per square meter.
• 1 lux = 1 lumen / sq meter = 0.0001 phot = 0.0929 foot candle (ftcd, fcd)
• 1 phot = 1 lumen / sq centimeter = 10000 lumens / sq meter = 10000 lux
• 1 foot candle (ftcd, fcd) = 1 lumen / sq ft = 10.752 lux
How to measure ?
A light meter (also called lux meter) is very useful. A light meter measures the amount of visible light illumination in a given area tested. Illumination is expressed in units of LUX (metric) orFoot candles (English).

The cost of lighting – infographics

Here is an infographics from the website, featuring the cost of using incandescent light bulbs, CFL bulbs (comact fluorescent bulbs) or LEDs.

The average lifespan of a led is 50 times longer than an incandescent light bulbs. Price is also significantly higher, even nif LEDs are getting cheaper 

However, we have to bear in mind that incandescent light bulbs are less used than in the past. In the USA, incandescent light bulbs are disappearing In 2014. In Europe too, incandescent light bulbs are being phased out. By switching to compact fluorescent bulbs,  companies and industries can reduce their negative contribution to climate change and save money at the same time.

The initial higher cost is quickly recovered, as these bulbs use only a quarter or a fifth of the electricity used by incandescent bulbs, and last much longer. Over its lifetime, a single compact fluorescent bulb will save you approximately 250 $, and their price is decreasing.

Tunnel lighting

túnel-bielsaThe primary objectives of tunnel lighting is to ensure traffic safety by illuminating all important objects during the journey of vehicles, and to improve visibility and comfort. Proper lighting in road tunnels will ensure that traffic can enter, pass through and leave the tunnel with a great level of safety. These aims are achieved by the adequate illumination of the tunnel interior, which allows drivers to quickly adjust to the light within, identify possible obstacles, and manage to leave the tunnel without reducing speed.

For that purpose, it is compulsory that the carriageway and the tunnel walls give a clear picture of the road. The road markings and stripes should also be visible, and tunnel lighting should ensure that objects on the road are visible at a sufficient distance.

Lighting must then ensure an adequate luminance level on the road, throughout the tunnel, and that luminance ha to be distributed uniformly on the road, in wet or in dry conditions. The lighting should not give rise to glare. Read more

Lighting for the food processing industry

lighting food proecessingLighting in food processing facilities has its own specific lighting constraints. Some areas of critical production require specifically designed lighting solutions and light fixtures. Food processing and preparation areas are extremely critical environments. High visibility, and also well-distributed lighting is required in all food processing industries

Industry standards and regulations have very stringent requirements, which mean lighting for the food processing industry must meet particularly demanding criteria. The lighting fixtures must withstand rigorous cleaning protocols and also support extreme high and low temperatures. Read more

Lighting in parking lots and car parks

A well-lighted parking lot is a key pointlighting car park for a shopping center or a building. Well-lighted car parks do attract customers, improve traffic, as well as the safety of pedestrians. A parking lot that lacks efficient lighting may result in wasted energy, low pedestrian security, and less attractiveness, which may affect your commercial results. For these reasons, choosing the right light fixtures will result in positive effects for any parking lot.

A number of issues can arise in car park lighting applications, such as light loss that occurs due to lamp depreciation and the usual wear of the components of the light fixture. Light loss can also take place when external elements such as dirt and moisture break into into the housing and accumulate on surfaces of the light fitting, which may result in lower light efficiency. Another common issue in lighting of parking lots is related to light distribution. A luminaire’s vertical and lateral light distribution can affect the quality of the lighting installation of the car park. For instance, horizontal and vertical illuminances which are below recommended practices may reduce the visibility of approaching vehicles or pedestrians. Horizontal illuminance uniformity is important in parking lots for both comfort and safety reasons, and you will have to select the appropriate luminaire based on the required illuminance uniformity on the ground.

Lighting solutions for educational facilities, schools, universities, institutions

lighting education

Lighting at school should provide a high visual comfort by ensuring an adequate and appropriate illumination level and strictly preventing the risk of glare. Lighting system has to respect the legal standards especially safety standards for electrical equipment, and to enable the rational use of energy by promoting the highest energy efficiency.

When designing the lighting system for educational facilities, the designer has to pay attention to important criteria which affect the quality of the overall lighting solution:

– Colour temperature:

The colour temperature of a light source is a numerical measurement of its colour appearance. This temperature is expressed in Kelvin degrees. Colours and light sources from the violet/blue end of the spectrum are referred to as “cool,” and those toward the red/orange/yellow side are “warm”. Light colour may affect the mood, and learning behaviour. Cool light lamps will provide similar outdoor environment, which may help some students who can’t stand staying inside for hours, while warm colours lamps will provide a more relaxed, non-threatening learning environment. A colour temperature between 3000–4000K is generally recommended for classrooms

– Light quality:

The Colour Rendering Index (CRI) expresses the quality of light. The CRI is a scale from 0 to 100 percent indicating how truthfully the individual light sources are able to copy the colouring of the object compared to the natural daylight. The higher the CRI the more faithful the colour reproduction. Light sources with a colour rendering index above 85 are recommended for classrooms.

– Energy efficiency:

Energy-efficient lighting directly affects lighting costs. By selecting efficient lamps the number of fixtures required in a school can be reduced. To calculate the total lighting costs, you should consider beyond the purchase price the average maintenance costs (cleaning, lamp replacement).

Energy savings:

Lighting can be an area for large gains in energy efficiency savings. The figures show that inefficient lighting systems in classrooms may represent 50 to 70% of electricity bills in many school facilities. Airfal offers efficient lighting solutions that help reduce energy costs while providing high quality illumination for students and teachers. Airfal lighting solutions for educational facilities (schools or universities) improve the feeling of well-being of the pupils and teachers, providing visual comfort and eye-protection that promote effective classroom teaching and learning in friendly and stimulating atmosphere.

Lighting fixtures for gas stations

petrol pump luminaireLighting is a key factor for the proper functioning and the commercial success of a gas station. Lighting will guide your customers in the service station safely and with maximum visual comfort. Access and parking areas should be properly lighted, giving motorists a first impression of the station. Good lighting will help create an atmosphere conveying safety and quality. Researchers have found that the number of drivers turning into a gas-station and consequently the turnover of the business is affected by the quality of light. Better lighting encourages drivers to use a gas-station. Naturally, people are drawn to businesses that give a stronger sense of cleanliness, friendly service and an environment that feels safe and secure. A side effect of this tendency are the increased energy expenditures.

Lighting and fixtures must be designed to improve the energy efficiency of the petrol station. The costs related to lighting can significantly impact the financial results of your service station. In many cases, installation of an efficient lighting system will result in a significant reduction in energy consumption. Read more

Lighting in offices and workplaces

luminaria oficina

In the past, fluorescent tubes were used to illuminate workplaces, resulting sometimes in cold atmospheres, and inefficient lighting. Today, we must take into account multiples factors, including the quality of light, luminous efficiency (how well a light source produces visible light), the design of the lights , and  energy efficiency.

If lighting at the office is not adequate, the workers may get tired quicker, with more visual fatigue, which may affect their performance. To optimize work efficiency, we will therefore have to choose the right lighting. Not only does the lighting system must guarantee visual comfort, it must also contribute to create a pleasant lighting atmosphere in the office. To boost productivity of employees, a high level of illumination is required at the office. This is essential, since a physical and psychological well-being result in higher productivity.

For efficient lighting, we must take into account the activity undertaken.  Lighting levels should match the workplace and the work tasks being performed. The different areas which will be illuminated, the number of jobs, will also influence the lighting system and the quality of natural light, as well as the energy consumption induced. The laws and specific rules for office lighting should also be taken into account.

Visual comfort is influenced by many aspects of lighting . Proper lighting makes all work tasks easier. People receive about 85 percent of their information through their sense of sight. Appropriate lighting, without glare or shadows, can reduce eye fatigue and headaches at the office. Direct glare from the lights makes it difficult to work with computer, and over time can cause eye irritation to the employee . The ambient lighting usec should be low or glare free. Indirect or direct/indirect light fixtures provide the best lighting solutions for many offices. This kind of light fixture hangs from the ceiling and gives more even illumination. The office should be arranged to minimize glare from overhead lights, desk lamps, and windows. Excessive contrasts cause also variations in the adaptation of the eye , which slows down the work and result in errors .

Generally speaking , the minimum levels of lighting in the workplace are defined by regulations.  These levels are measured with a light meter and expressed in lux , and this lighting unit is produced by a lumen ( amount of light emitted by a light source ) on a square meter of surface. The CIBSE Code for Lighting recommends a maintained luminance of 500 lux for general offices (e.g. writing, typing, reading, data processing, etc.) and for CAD work stations and conference/meetings rooms. Where the main task is less demanding, e.g. filing, a lower level of 300 lux is recommended. 

Although it is recommended to have natural light in offices, there is no minimum requirement. But no natural light throughout the day ensures uniform lighting , and therefore it is recommended for to combine direct and indirect lighting in offices. To achieve this double exposure to direct and indirect light, we should use different light fixtures. For example, direct light from the ceiling ( neon tubes or LED lighting integrated in the roof ) can be completed with indirect lighting (desk lamps , wall … ) .

How to manage lighting for hazardous areas ?

atmosfera explosible

A hazardous area is defined as any place in which an explosive atmosphere may occur. Hazardous areas may exist due to flammable gases or vapours or combustible dust. Explosions can cause loss of life and serious injuries as well as extensive damage. If there is enough quantity of flammable substance (the fuel) mixed with oxygen (the oxidizer), an ignition source (e.g. an electric spark) is sufficient to cause an explosion, in which combustion spreads to the entire mixture yet unburned, and can be caused by unadapted light fixtures.

Where can explosive atmospheres be found?

Many workplaces may develop or have activities that produce explosive or potentially explosive atmospheres. Examples include places where work activities create or release flammable gases or vapours, such as:

– Vehicle paint spraying,

– Metal processing facilities, where explosive metal dusts may form.

– Processing units of raw materials that generate fine organic dusts such as grain flour or wood manufacturing units.

The potential for explosive atmospheres can exist in a range of mainly industrial locations such as mines, factories, agricultural silos, and oil and gas platforms, water and other chemical processing environments.  There is a wide range of products intended for use in such areas, including control equipment and sensors, transformers, fans, pumps, compressors, fork lift trucks, and lighting.
