Thanks for the reply Little bopeep. Yeah think I read that I'd only lose around a 1/4 of reflective or less, and the white curtain is just to keep some light going back but its more about the black keeping that BRIGHT glow contained while still having easy access. It's face is inches from my bed so no room for doors or an extra wall. Either way my 135W BS will be better then my 15-75W spiral mini cfl! :smokebuds:With my skillz I'll still need ALOT of luck.
