Spiral CFC's contain their own ballast. So you only need what a normal incandescent bulb needs in terms of wiring. If you are ever in a thrift store, look for one of those ugly brass or whatever material lights that were designed to hold 3- 6 incandescent bulbs over a mirror. They are typically only a few bucks and once you remove the ugly shiny metal piece you have a harness for 3-5 sequentially wired spiral CFC bulbs. Put it in a more suitable reflector or housing like a gutter and put globs of silicone over all the connections and you have a cheap bright light for well under ten bucks ( not including bulbs). Do this at your own risk of course.
