the shop light works great! less that $30 for the fixture and bulbs. lights up the tank pretty well, but the ends are a little dark. raising the light should take care of that. i'm planning on getting another fixture to put in front to get even lighting from front to back. i'll be suspending them about a foot or so above the tank. i'll get that done in a few weeks.
