Just think... If HPS produces more lumens per watt then the assumption can be made that it burns cooler. Since more electricity is transformed into light, then less electricity is left to produce heat.
I could be wrong on this. But none have corrected me on it.
I think I have heard that somewhere and it makes total sense. This would also mean I would have to have an external ballast located outside of the cab. Its something I definately want to do in the future, but I think I am going to stick to CFLs unless I can get a HPS for around 60 bones. I know there are some security lights at HomeDepot, but I'm not so sure on trying to make a reflector and mounting for one of these.

Im about 250 deep in the cabinet now, the costs add up a lot faster than I was expecting. All I have left to buy is nutrients and seeds.
