Subfreezing Temperatures? No Problem for LED Lighting

LED lighting excels in cold temperature environments.

At Pegasus Airfield near McMurdo Station Antarctica, the runway is illuminated with LED lights. Temperatures range from a high of 12°F down to 0°F and lower.

Large commercial cold storage facilities are often illuminated with LED lighting.

Finally, one of the fastest growing sectors of LED lighting over the last few years (2014 – 2017) has been LED outdoor roadway and area lighting – a type of lighting that obviously must withstand cold winter temperatures.

What these examples demonstrate is that cold temperatures do not preclude the use of LEDs. In fact, LED has become the lighting source of choice for cold temperature applications.

According the Lighting Research Center at Rensselaer Polytechnic, cooler ambient temperatures actually improve LED lumen output, “the cooler the environment, the higher an LED’s light output will be.” While the human eye may not be able to detect this incremental increase in light as ambient temperature declines, the important point is – LED lighting and cold temperatures are a good match.

In addition to not affecting light output, cold ambient temperatures do not alter the instant ON feature of LED lighting, the energy use nor the rated useful life.

For virtually all commercial, industrial and residential outdoor or cold storage lighting where low temperatures exist, LED is an ideal light source.
