I hadn't even realized that my new 5 gallon had an incandesent until I was putting it together. The light looks too dim, I asked lfs guy if I could get a higher wattage and he said it would get way too hot. So my question is why do all of the small hoods come with incandesent when it gets hot, whereas the larger ones use florescent which don't? I see no benefit to incandesent at all, do you?
