Well there's your problem.!!!

I'm reluctant to believe anyone in the world that would possess any knowledge of how to manufacture a LED modual would allow this to happen during manufacture!!

I had purchased a large quantity of these COB LEDs 6 watts They look very nice when first installed then begin to flicker from which they proceed to dim or go dead.

I have so many irons in the fire I'd just change them out and chaulk it up to more ______'s crap!!!

One MR16 LED had dropped on the floor and came apart. Looked inside, Couldn't believe my eye's!!! ONE small drop of heat-sink compound and the LED wafer was actually not contacting the heat sink IT WAS HANGING ON THE WIRES!!!

WELL THERES YOUR PROBLEM!!

I Guess I'm going to slowly take them apart and either epoxy or silicon the wafer onto the heat-sink like it should have been done during manufacture.

Gary Gary had found silicon to work well with the flat plate solar panels for heat transfer. I like epoxy.

Anyone like to chime in??
