12V burnt Cree LED bulb repair

Cree Luxeon LED bulb repair
How to fix MR16 type 12V LED bulb by Avi
Don’t trash it, don’t make the situation worst. You can contribute to keep our planet cleaner.
You can repair it and I’ll show you how.
These kind of bulbs uses few Cree led components and in most cases one of the leds fails which causes the bulb to stop emitting light or emit a very dimmed light. Replacing the faulty led will usually solve the issue and allow further use of the bulb.
This page will show how I replaced a fault internal led and fixed the bulb.
DISCLAIMER – Important!
- Phillips head screwdriver
- Solder iron and soldering accessories
- Working Cree / Luxeon led (this could be taken from another fault bulb)
- Thermal grease / heatsink compound

Leds driver PCB (small one) can now be removed which will release the leds PCB.

This part is attached to the metal housing with a thermal grease. If this is the case, clean the grease to allow easy handling. You’ll need to apply new grease when assembling.
Desolder the fault led and solder a good one keeping the same polarity.


Have fun and enjoy your lighting, Avi
