I was speaking more to the fixture and not the bulbs. Definitely the illumination has to be aesthetically pleasing. My plan was to go with the fixture and if need be, build a nice enclosure to house it and mix up the spectrum by using a couple other smaller aquarium lights I have hanging around.
What have you found to be a good combination with the lighting that is pleasing to the eye. This fixture is actually coming with a 6500 k blue 54W. I'm going for low tech, no CO2. I figure I'll hang the fixture and if need be can raise or lower depending on what happens. If the lighting is harsh itself, one drawback of using on 1 t5ho...I'll just add to it with the smaller bulbs. I'd appreciate suggestions, because that is what I'm reading about now.
