Yeap... and then there's the bulb, the brackets, the turns and bends in the ducts, the fittings, etc.

turtle420 Reviewed by turtle420 on . Air Circulation Question Okay, I have a difference of opinion on the way my fan for cooling my lights should be set up. Zandor tells me that they should blow the air through the fans; I have it set up so that the fans are on the exhaust side of the lights and draw the air through the lights. I still fail to see what difference it make unless it's just personal preference. I'm really at a loss on this, because I just don't know what diff it makes; air is air, and it's going to take the same amount of energy to pull Rating: 5
