I have a couple of identical 120w chinese lights. 2 dimmable channels, one white, one blue. One got wet and about 1/2 the leds went out...using parts from the good one, through process of elimination I determined which component was bad. Its easily replaceable, but I can't find one to buy! I've been all through ebay and LED suppliers and cant find it. I think its a driver or a power supply. It has a dimmer on it. Can anyone point me in the right direction for a compatible replacement?
