yeah, it sounds funny upgrading my 130watt PC to 96 watt T5's, but with T5's you cant think of it as WPG's. With individual reflectors, T5's are comparable to Metal Halides. I also plan on getting a clam, most likely a squamosa, and everone says i should have no problem keeping him in the sandbed. I chose T5's for the long bulb life, and electric efficient.
