I'm going mid tech? I only say that because I have the T5HO and a 25 watt UV sterlizer running with 2 Magnum 350's. It isn't quite low tech and certainly not high tech. I have a 55 gallon and am only lighting one of the bulbs in the fixture since two would be beyond high light in this tank. One bulb registers at medium light according to Hoppy's graph in another thread. I was shooting for med-low light and couldn't find a normal T5 fixture in my price range that could handle two bulbs. So I opted for the T5HO and using only one bulb.
