Lol, before i found ths sight i was tooling around and bought one. Hehe, it was crap but interesting. In veg the lights strained toward one le on the panel. U cud tell it was crap because the lights would strain more towards the cfls than the leds. I tried just leds then both leds and cfls and they forgot about the leds. I bought a cheap 30 dollar one and i read that u really need those hude industrial ones. I new this but it was on e bay for 30 intead of 50. I switched to hps after that. I read everyhthing about leds their was, and well if y buy the best crap u might get something for a lotta cash. everything helps tho. Hid cheaper and i think rocks all ass but i seen some grows where they put thise little panels onthe side and the hid on top. good luck i dont want to disapoint yu, you oubd liek myself 2 months ago before i went and bought a 400 watt. do that and wow.
