I know this is a direct Chinese led thread but I think all lights come from China originally. So my room has a lot of light. 18-Cree 3070 50watt cobs, 2 315 watt cmh, 90 watt Cree LED bar, 500w of Cree monos, some smaller 18w eBay screw in cobs and 2 Mars hydro 600's so recently I picked up a lot on eBay which sold 4 Cree 3070's with pin heat syncs, meanwhell driver basically everything but a housing. Last night I sort of temporarily rigged it up in place of the 2 Mars LEDs and I am so amazed!!!!
I always based my lighting decisions off of brand and efficiency but never expected this. No exaggeration at all, how can 200 watts of cobs appear to be 3 times brighter than 1200 watts of LEDs. It's sick!! The 3070's are bright but they don't even seem to be half of the 3590's and the best part was the kits only 430$ shipped. Yeah it's a little more than most want to spend seeing Mars sell for 130$ but like I said there is no comparison. I can't wait to build more rooms so I can fill them with these. They do draw less but another bonus is the heat is so minimal it seems like they wouldn't need cooling if they were in a room by themselves. 2 inches away you can't feel heat at all and there is no fans dispersing the heat like most lights that hide the fact they are blowing tons of btu's into the room.
