How well do LED lamps work in cold environments?

LED lamps actually “prefer” colder ambient temperatures. They are ideal for freezer cases, cold storage, warehouses, outdoor use, etc.

While we are on the subject of temperature, heat is generated within an LED at the internal junction where light is produced. Manufacturers thusly incorporate thermal means to dissipate that heat by means of heat sinks or venting.

Typically, LEDs are warm to the touch (unlike burning hot incandescent or halogen lamps). This is due to the built-in thermal characteristics.

Therefore, it is important to look for reputable manufacturers that you can trust for quality products that last and produce the amount of light you expect compared to traditional light sources.
