I've got some questions about T5 fixtures for you all. I am going to place it on top of the screen which means I need a unit that will sit on top. I have the zoomed "viv" which is just a glass enclosure, but the top is 2 separate screens. The back is wider than the front section and they both slide out instead of being lifted. Now I know the zoomed T5 fixture will sit on top, but I don't like how wide it is. I would like to get the sunblaster with reflector but I have a feeling that the light bulb would rest on the screen. I am looking for people that own the sunblaster and other fixtures with reflector that can verify it will sit on top of the screen without having the bulb rest on it.
