peanut you could just wrap some tin foil in the inse of the light and that would work great. I wouldn't expect that it would be moving much. Just tape it down!
with t8 and t12 you pump a lot off watts for little amount of light. if you really looking into plants you dont need a $450 fixture these will work. http://www.fishneedit.com/t5ho-ligh.htmlWould it be ok if I used 2 of these

which would be only 40$ for 160 watts for a planted 75 instead of the 450$ lighting fixtures on Drs foster and smith
http://www.rexgrigg.com/light.htmlPeople that use shop lights over tanks. Sure they are better than a standard strip light but they still suck. I once had a 55 gallon tank with 160 watts of shop lights over it. And it sure did look bright. But I had problems with a lot of my plants. I switched to a single 2x55 watt kit from AH Supply and actually got more usable light into the tank. Sure the shop lights gave better coverage in the tank and into the surrounding room but the AH Supply kit basically blows the light straight down into the tank where it belongs.
