one thing I noticed is if the panel is on and I'm handling it, it doesn't take much pressure or flexing to cause the emitters to go on and off. We may be damaging them not handling then carefully enough while installing.
You could be right. I can't remember seeing reports of similar failures with cob style lights. Pressing the panels onto a slightly curved surface may cause enough stress to weaken the soldered connections.
You guys may be on to something, here.:h
Thanks, Tenbear, for linking DaveSparky's test and the report on your experiments. I might try to duplicate your experiment with flexing the board.
Jim, I know you've had more than a few LED panels. Did you experience the diodes interrupting on all of the panels you flexed or just some? My theory is that not all Asian LED panels are built the same, some being less prone to failure, some more.
I haven't had the time or inclination to find out why but I have a variety of LED panels from different Asian sellers and even those with identical layout (36-->36 SMD, 48-->48 SMD) can have slightly different luminescence. Some, or all of it, may have to do with voltage drop across the TT's wiring and switches. BTW, none of my panels have failed and do a great job in the CB/Hilton.
