Lights suck air in at the top and blow out the sides, at least mine do anyway. All you need is a fan in the top area sucking air out and an open vent toward the bottom for the air intake. I suggest a temp/humidity controller for the fan so it will keep it stable. The efficiency depends on how cool the air going in the tent is.
I turn my 750cfm fan up to about 1/4 to 1/2 speed and just unzip the bottom of the door. It stays at ~80, same as the room its in. When I first set it up though I had to crank the fan to full, cause my apartment was 85+. Soon it will be cold enough to just leave the fan on low. An alternative is to just leave the doors open and it will do the same.
I was thinking that if you have a 4x4 tent, get a 4x4 piece of plywood and cut out the holes for the fixtures. Basically separating the heat up top from the light below. I think this would make it easier to use CO2 without an air conditioner.
Does anyone know anyone who's using CO2 and LED? I don't see how you could run co2 and the lights for very long before the heat builds up and you need to vent it out. It depends on your wattage, efficiency, tent size etc... I'm using over 1000w right now in a 4x8.
