XC, I've got a cool tube in my veg area and it's great. Is that 3 x 1000W you have in one run? What have you got pulling the air over them? I want something similar to my leaky air cooled reflector in my flower area though. I want to be able to mount a couple bars on it that will hold some cfls as well, and the cool tube reflectors just can't handle that well. That is unless maybe I make my own, like in my flower area.
