It's cool, allright, as long as you put a fan on the system. But even without a fan, the overdriven NO bulbs get no hotter than a standard 55w PC bulb (which is pretty stinkin hot). I added a fan to my CSL PC strip and bulb life has increased tremendously.
I've got an old Perfecto twin strip hood for a 55 with some fried ballasts. I'm going to retrofit two of these ODNO ballasts into it and see how it looks. Might try to sell it, but shipping would probably be expensive.
