Hows this for temporary cheap lighting for a FOWLR?

Good info Ross. But he did say from his subject that he wants it for his fish only tank with live rock. He won't have corals or clams. I don't think liverock needs high color temperature lighting. I assume the only photosynthetic life on the rock will be Coraline algae and I think algae does prefer the warmer, lower K light.

Halogen lighting is slightly more efficient than normal incandescent lighting which, though not optimal, is commonly used in fresh water fish tanks.
