Lighting

I am converting the hood that came with my aquarium to cfl lighting. My question is can I just have 1 bulb for my 20 gallon tank? It's 24 inches high and 16 inches deep. I want to grow low to medium light plants without co2.

Converting from what to what?
If you're using spiral fluorescent bulbs in place of incandescent, the Sylvania, daylight, 23 watt, "Now smaller than ever" spiral bulb is great. Two on a 20h will give you low or moderate lighting depending on the depth of the substrate depth.
