I have had a T5 8-bulb Tek light on a 120 for several years.
I get tons of growth on easy SPS (Monti cap taking over 1/2 the tank, Montipora digitata growing like crazy), the Montipora confusa is growing moderately, however a Horn coral has not grown at all. I haven't tried any other SPS. However there may be other factors hindering growth like flow, feeding etc. I haven't changed my T5 bulbs in 3 years or so, I guess I should. I read that an actively cooled T5 fixture (like the ATI power module fixture) will give much better light output than a Tek fixture. I don't know if this is true or hype. I believe that the amazing European T5 tanks you see on RC are running this sort of fixture.
