FAQ

Why has the colour appearance of the LEDs changed after some period of use?


There are several possible reasons why this happens as follows:

 

  • The LEDs are being overrun by the use of inappropriate driver.
  • The application temperature is different from the operating temperature noted in the LED datasheet.
  • There may be heat build-up due to improper thermal management.
  • The phosphor may have degraded due to overheating or other reasons.
