What are you asking? The long flouros usually aren't as powerful, except T5's but they're more expensive for flouros. What kind of flouro do you have? what is the color temp? The lower, or red, spectrum of light (~2700 Kelvins) is best for budding. I've smoked some really dank Auto Hindu Kush grown from CFL's, and currently am using them for my grows. You get much more bud with high powered lights (MH, HPS), because they penetrate deeper under the canopy better, but flouros are good cuz they dont get hot, therefore much less space is needed - People grow inside computer cases with CFL's.
You can get a 60 or 65W 2700K CFL at Home Depot for $13. I'm pretty sure it uses the common medium socket too. You could also mix spectrums by using ~6400K bulbs. Those are commonly sold in 26W (they say 100W equivalent, but forget that). 42W 2700K bulb are pretty common too. You can use Y connectors and plugin converters to make an array of bulbs on a surge protector.
Hope this helps. Sorry if you already knew all that.
