curious to see how this turns out.....good luck man! :jointsmile:
For the 50w panel in the PC case, the burn didn't occur until about 1-1/2 or 2 inches. For the 120w, about 9 inches. On the other hand, at those same ranges, I can feel the light pounding against my skin (makes it tingle!) so to some degree I'm not entirely surprised. The top-bin diodes are certainly killers.
