Hi All,
First post here.
Got a LED floodlight that filled up with water and am trying to repair it.
Steps taken;
Ive read MKP caps are for AC line filtering and shouldnt affect function so am not really sure that is my issue.
Has anyone got any suggestions on what to try next?
I am happy to replace the driver with a good quality replacement, but not sure what to pick as the SMD LEDs in diode mode read about 2.5V. Without knowing too much about how to size constant current drivers for LED arrays I would suspect I need something around 60-90VDC (as the LEDs are 24 in series)Looked on meanwells website cant see anything that might suit.

Steps taken;
- Cleaned up all water and plugged in to test function
- Driver board with no load spits out around 85VDC
- Soldered LED back on and the LED flashes straight away
- Also noticed one led on one of the rows was faulty causing the row to stop working - shorted that LED and now the row works
- After doing this the LED seemed to work be then flashed after about 5 mins of use
- Then went over the board and re-soldered all connections on the non SMD side
- Still flashing, so suspected faulty capacitor. All test within reasonable limits (100uf caps were around 90uf) except the MKP caps which test at 0uf
