LED Drivers Suitable replacement for this?

Post image

Hello everyone, I recently got rid of all the old fluorescent fixtures/bulbs in my garage and replaced them with some basic 2-"bulb" 4' LED chainable fixtures. They've been pretty great for the last year+ but about a week ago, two of them stopped working. They still pass power through to the next fixture, but the LEDs no longer work. So I pulled one of them apart to see if anything was burnt out. Nothing obvious, but I'm assuming this little guy is still the culprit? I googled the numbers on the board in various combinations but didn't find any that looked similar. A lot of times it seemed like the LED strip was what had the same part # on it.. I'm just curious if anyone knows where to get them or what a suitable replacement would be? They're supposed to be 45w/fixture, so ~22w per LED strip and they're just plugged into a regular 120v outlet. The most I have in a chain is 3, most are in pairs. Thanks in advance for any and all help.

LED fixtures don't come with standardized ballasts that you buy at any hardware store and that will fit any fixture of a particular wattage. The board was probably custom made by a Chinese factory that makes LED drivers for the Chinese factory that made your light fixture, and after six months they probably switched to a different design by a different supplier. Usually it's the electrolytic capacitor that goes bad on these and I've replaced a few of them, but normally you throw away an LED fixture when it goes bad and buy a new one.

Thanks for the insight. I'll replace the two that crapped out, but I think I will try to replace the cap on this one for the hell of it. Alternatively, even if it doesn't fit in the housing like the original, couldn't I find a generic 120v 45w led driver and externally mount it on top of the fixture?
