I'll be tackling this over the next couple days, my only question is what's the heat output as compared to the normal florecents? Just trying to figure out if I need to vent add vents or not, and if so, how exactly I'm going to do that without too much extra extra light pollution, haha. My 25 gallon as 30 w of light over it, and it's borderline blackwater, talk about low light. Trying to fit 50-60 watts in the limted space afforded by my eclipse 2 hood, this is really the only way that makes sense, thanks for posting.
