First post on the forum but read alot. 1st want to thank everyone for the great information on cob leds. Wanted to replace a 400w hps due to height restriction in my 2x4 tent. So went with 4 cxb3590 3k 72v and 4 3.5k alternating. 4.9inch heatsink from heatsink usa. Active cooling on low voltage just in case. Mw 185hc700a. 2nd jerry is the man. 3rd finished one heatsink with 4 cobs and i practically blinded myself. Wow They are bright. Next step is turning down the amps and let the efficiency climb. Haha. Thanks again.
