Will spiral screw-in CFLs work?

I have a 20" high tank and I am currently using three 27W spiral screw-in compact fluorescent bulbs to light the tank. I know that these spiral bulbs lose strength due to the restrike. What kind of plants do you guys think I can grow with this lighting?

re-strike refers to lights that require time to re-light if they are turned off intentionally or due to power failure or brown out. all bulbs are affected by this to varying degress.
this is why T5 bulbs are more efficient that the sprial bulbs, the smaller diameter reduces the amount of lighting reflected back onto the lamp.
