LED Lighting
Why do some lamps become darker after using for some time?

This is called light decay.

The causes of light attenuation are as follows:

  1. The quality of the LED is not good, and the brightness will decrease rapidly with the use time.
  2. Thermal issues. If the LED luminaire itself does not dissipate heat well and the LED chip operating temperature increases, it will accelerate the light decay.
