I'm guessing ill try too rewire the whole rig and see if I still have the problem
no thats not good idea, look what Greengenes707 wrote on page 1:As already suggested, you could try the driver on 1 COB at a time. That way you'll know if it's the driver or the wiring.
Make sure you didnt scrape any of the insulation from the wire when you fed it through the heatsink. It can short out on the heatsink causing exactly what you mention. Check the insulation real good in these areas. Also, if that is duct tape on your dimmer leads, I'd use the proper electrical tape on them. Its a good practice to ground from the green earth ground from the AC side to the heatsink as well. Good luck with your light!I recently built a led panel with 3x 36v cobs with a erao lcn200w 180t. Wich I bought from cutter electronics. It's a 1800mah driver and it says on the website it will run between 2 and 3 cxb3590 36v. And for some reason they were working fine wen I first powered them up then they started getting dimmer and dimmer a few moments later. Idk wtf Is happening . They are not very bright at all now... Please help? They sorta flicker too
