I'm going to use these bulbs on my new frag tank and was wondering what the suggested height above the water surface is.

Depends on what optics you get, 40* you will have to put up high or you will get a spot light affect. There is 60* and 80* also, depending on how many you are going to have you will be able to keep the 80* lower to the tank.

thank you for the info. I just looked at the bulbs and they are 40's. I'm going to put them on an adjustable bar hung from the ceiling so I can adjust the height as needed.
