Prow I know many people who are successful using T5's and some of them have tanks loaded with SPS and Tridacnads BUT the tanks are relatively shallow AND they're using a ton of bulbs so the cost in the long run could be considerably higher especially if your replacing these bulbs every 6 months due to the fact these bulbs are being overdriven, this shortens their lifespan.
Have you checked this thread at RC ?
