Head on down to your local grocery or hardware store and pick up a
compact
fluorescent bulb. At home depot, I saw a 25 watt fluorescent that
screwed
into a standard incandescent bulb socket. There may be others. If your
existing tank hood has adequate clearance, this would seem a simple lamp
upgrade really, really cheap. On the other hand, you could go to
http://www.ahsupply.com and buy one of their kits.

I still haven't seen any information about the spectrum of these compact
flourescent lights. Does anyone have any evidence that they provide the
necessary wavelengths for optimal plant growth?

you mean as compared to the 8 watt incandescent that generally comes with a
10 gallon tank? It's got to be an improvement.
