Full bath, too! That box in the bath is where I keep all of my various shop manuals; it's a footlocker from the Korean War. 220/110VAC. On the wish list are a four-post lift, a 30-gallon compressor, and a bit more lighting.
A few weeks ago I saw a Jay Leno-Video - he had a guest from Titan LED and they talked about the lighting in Jay's garage. Maybe they also have something for you? LEDs are expensive, but they save you a lot of money in the long run.
