One idea I picked up on the recent Charlotte shop crawl (Second stop...sorry, my mind is a terrible thing...can't mamember names anymore

) was to use multi bulb bathroom light fixtures (like over the sink) mounted flush on the ceiling picked up for I think I heard mention of a few bucks at the Habitat RESTORE. Double bulb adapters were inserted into each socket. 100w or 150w CFL bulbs inserted into each adapter socket. This results in a bunch of light output without overloading the fixture if you need lots of cheap light. I did it on the bulbs in garage door opener (directly over my tablesaw) and it is a big improvement vs the 2, 60w incandescent bulbs in there previously.
