hey eveyrone, right now i've got a 400w hps with a regular batwing reflector. It creates alot of heat so I've been looking at reflectors that are completely enclosed with ducts built in to easily hook up intake and exhaust. My question was how much of a difference in temperature should I expect when using this reflector rather than the one I have now???
a lot. when I went to air-cooled, I saw a 15 degree drop in temp. AND, now I can use CO2 on my plants much more efficiently.
I like THESE, they let you get your light right near the tops of your plant without burning and they help prolong the life of your bulbs.
