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.
