If you wanted something a tad bit better, and just a bit fancier, try an LOA fixture (Lights of America). You can get them at HD. Uses a screw in sort of bulb, but it's a 65 watt bulb in a reflector that you can mount.
I did get mine from Doc Roy, and it works great. Bulb is about $28 to replace, so not incredibly expensive, plus if you are just growing Chaeto, you don't really need to replace.
