Hey buddy....I don't want you to think we're baggin' on your light...because that is certainly not the case. That thing will totally grow some weed...and pretty good weed at that, probably. There is one thing I would like to teach you, though about LED manufacturers. Its all about marketing for them...they'll call it 600 watts...but the true wattage is measured at the wattage consumption, which for that light is 277 watts. I have a "1200" watt led....it pulls a little less than 600 at the wall....but its not the same as say, a 1000 watt (true watt) hps light or something.
I bet every body here has paid for something they weren't happy with, and we hate to see it happen with others. If at all possible, return that light, and buy a single autocob (exact same price as what you spent), and buy another one when you can, and so on. 4 of them in that tent will be freaking awesome, and will last you forever! And if growing isn't for you, I guarantee you will not have a problem selling them!
Like I said...we're just trying to help a brother out!
