I would use HO T5 instead of CFL bulbs.
That, or just get a 10 pack of 9w LED bulbs, and screw them in instead. Make a fixture if you have to, or use a couple of those 4 way bathroom vanity light fixtures or something. When you remove the globes, they are way more efficient than CFL. Might as well veg with LED if you are going to flower with LED, right?
