The best lights are going to be halide or HPS, but they're expensive, expensive to operate, and give off a lot of heat. I have 64 sq ft of growing area under fluorescent shop lights. A 4x8 sheet of plywood is 32 sq ft. I have 2 of those covered by white FRP panel. Each sheet has 11 4-ft shop light fixtures over it with 2 bulbs each.

If you're only talking about a plant or two, you could probably get an easy to find clamp light with reflector hood for under $10 http://www.harborfreight.com/clamp-light-with-aluminum-refle... if you're not particular about appearance, and use a 100 watt equivalent (or brighter) CF bulb that favors the blue portion of the spectrum (cool white, as opposed to warm white or daylight).
