Ive been growing under 5 CFL's and im into day 33 of flowering. link) and i think my shits looking okay, so i think you should be fine. mind you that ive spent about 30 bucks, and it cost me an extra 5 bucks a month on electric bill. :D
Those lights are a bit far away, might make them stretchy and not be able to hold up big buds, lights need to be as close as possible without buring the plant. your going to prolly have to add more cfl's for flowering too. good luck man.
