Led problems

I used some acrylic to cover mine. Are the boards mounted onto a heatsink? If the are the best way to keep the cool is to have the fans blowing down into the top side of the heatsink to keep them cool. If the fan is not keeping the whole heatsink at a decent temp it could also be a heat issues popping the LEDs. I forget what the temp difference is before the led will pop but I know my heatsinks only raise in temp by 3-4 degrees.

I'll check out some acrylic. I used square tubing for the heat sink. Three rows of square tubing with 12 boards per tube 2.5 inches apart. 2 fans expelling warm air. The tubing is a little warm when touched this is after the lights have been on all day. I can add more aluminum to increase the heat dissipation and maybe place a fan on the end of the tube blowing through it.

I really think that its a heat issue now that I know what there mounted on. the cooler the leds are the longer they will last. If you can find some really small fans to put on the end of the tubes to blow threw them it should keep it a lot cooler. when mine have been on all day the heatsinks are cool to the touch cause the fans are on the whole time. Hope this will help with your issues and if you have any other questions let me know.
