T5 vs MH.....

I can't make sense of some of the info i have been reading about T5. From what I am reading T5 is as good if not better. I understand the heat issue with MH. How high should the MH be above the water line and/ or a glass cover? Any input would be appreciated.

I have neither but I think how high above your tank for the MH`s depends on the depth of you tank. I`m going to move this to the proper forum.

I have MH and I keep them 8" above tank. Temp swings at this height for me are about 2 degrees.

I own a HO T-5 and am very satisfied. It's a double tube 24" 48 watt fixture. It's cooler running than compact flourescents and metal halide. It does not require a cooling fan and the bulbs are less expensive, but you won't get the output as you would an MH fixture.
