Does anybody have these? Does it have that parabolic reflector which makes T5 so efficient? I was gonna get a 48" lunar aqualight for my FOWLR 55g, but i'm thinking about the aqualight T5 fixture now. I figure for a FOWLR, this should be enough. It's a dual 28w fixture. Would one be enough, or should i get 2? It's cheap enough that i wouldn't mind springing for another one if it would be somewhat beneficial. The only bad thing is that it looks like you can't use the legs to raise it off the top. It seems to just have extenders on the side.
