Dont know about his cobs but mine self regulate their wattage so they dont burn up.mine get pretty warm at initial start but after a few hours the heatsink is cool enough to touch and not get burned,its warm but its not hot and after they get settled in they run at almost 50 watts according to my killawatt meter. When i get home and lights on i will take some pics of my Frankenstein cob setup and the killowatt readings.
I was really against leds but the more i read the more i liked so im in the middle of my first run with led cobs oh mine are full spectrum. The onions luv the light and so do the girls at the moment.
