There are a bunch of threads on garage/shop lighting over at the Garage Journal forums. VERY active site and they are most helpful, just like Autopia
The Garage Journal Home
As for bulbs, as strange as it may sound you may want to check out the forums at Reef Central. Aquarium lighting is not really the same as garage lighting but I think those guys can probably give you a good idea on bulbs that put out the most light....
