Tagged with 'High temperature resistance'

LED lamps, modules and fixtures can be damaged by high operating temperature, with mechanical failure or significant drop of performance being the most common.

How a LED behaves when functioning at higher operating temperatures is directly related to its quality. High quality LEDs, like Nichia or Cree, will function within parameters at high temperatures too, while low quality LEDs will break down, change their color, loose brightness or a combination of these.

1. complete failure of the LED
2. light output is decreased permanently (Lumen Degradation) even if the issue with high temperature is solved
3. light output is decreased temporally while the LED functions at high temperature
4. the color temperature of the white LED changes
