I've got a buddy that bought into the hype and was very dissapointed.. He was already running 2 1000w hps and 1 1000w mh and wanted to add a 3rd flower room and tried the led's.. They really sucked and he had a shitload of them...
I'd stay away...
Btw.. i do have a set of leds that i pit under teh holes of my cornhole sets and they run them for 12 hours off 1 9 volt but thats about the only thing i'd use them for..
