I've used regular fluorescent lights for seed starting and that's always worked fine--you don't need special "plant lights". The catch with the CFL's is that they're small, and for best results with any light bulb (specially made for plants or not) you need to have your plants fairly close to the light for it to do much good. So if you've only got a couple of plants the CFL may work fine, but if you've got shelves full of houseplants you'd probably be better off buying a cheap shop light from Home Depot instead--the fluorescent tube bulbs in those are long so you can put a lot of plants under them.

Get the "daylight" type ones. They have a higher "K" rating which is better for plants. Read the back of the package for the rating.

I have had great success propagating houseplant cuttings (mostly rhizomeous begonias) using CFL bulbs.
Have a table lamp that is on all night (kinda used as a night light) - area gets natural light during day. Have placed begonia leaves with stem in soil in small pot then into plastic bag. Use rubber band around outside of pot to steady pot in plastic bag then suspend the pot/bag combo about 8" from the bulb. Do this using a spring loaded paper clip grabbing, top of bag and attaching to the pull chain of the lamp. The contraption acts as a mini greenhouse and works great.
