All high power LEDs produce heat as a by-product of lighting and must be adequately cooled to ensure long life and reliability. Failure to keep the junction temperature of the LED well below its maximum rating will result in:
- Significantly shortened life
- Reduced light output
- Change in color output (Especially with white LEDs)
- Complete LED failure
To help you select a suitable heat sink, we have put together this information page and heatsink calculator.
