The light that was still in there was a T12, so I assume that's what the hood was made for.
I want to get a new, better light for it, and was wondering if I could put a T5HO fixture in there without it exploding or electrocuting the water (that's already happened so far with this tank-not quite looking forward to another experience).
You didn't mention what length fixture but there is a simple, easy LED retrofit for old fluorescent or incandescent fixtures using LED lamps. The LED lamp retrofits offered by AH Supply
operate on 120 VAC (wall outlet power), do not require a transformer, ballast, or power driver, and come in 15 watt, 20 watt, and 26 watt output and are 6400K ($72 - $99). They have good PAR readings as well.
