So, I was looking though my dad's garage and there are a bunch of new outdoor halogen lights, I think they are 150w or 250w (you know the big rectangular kind you screw to the sophet of your house and they hang down in their sealed felfector box). I was thinking, with the right color temp bulb, these would work great. No ballast to worry about, very easy to mount, and really cheap. So why do we not use them?
I know metal halides are much brighter, but for the price, add one more $15 halogen fixture and all is well.
I know they get really hot, add a few cooling fans in your canopy hooked up to a different timer so the fans keep going after the bulb is out to get rid of the heat build up.
Bulb life is about 33% of that of a metal halide, but bulbs being so cheap i wouldn't mind changing the bulb once every year.
If anyone else has an oppinion on the use of halogen lights in the aquarium world, share your thoughts.
