Lighting Mars Reflector 48 hack

[Slater]

On my converted lights I stripped the leds and sanded the solder and paint off.

Now that's a good idea

I did this then flipped it over as the old face wasn't as even as the back side. Loaded up that massive 4mm thick with new paste and reattached it in the same holes. When attaching the cobs to the new face I drilled through the back side to center the screws in between the fins.

Sorry to semi hijack, I'm doing something similar.... I stripped off the leds, and I was wondering what to do about the pcb on the aluminum plate. Should I sand the whole thing off, or could I just strip the mask off to the copper layer? Then I could just remove the area the cob will be in contact with.

That side won't be flat once sanded and should be for the cobs. It's best to sand it as clean as possible and use the old front for the heatsink and use the old flat back for the cobs.

Thanks, that makes sense.
