You get more lumens per Watt from the LED's but the CFL's are cheaper to buy. I guess it's all about your budget. If you do decide to with LED's you can pop off the top plastic globe and gain about 20% more light energy. You can go with the 60 Watt equavilant and place the lights to within inches of the plants.
I wanted to buy a 300W LED instead of CFL's as I'm building a box for seedling/vegging. Using LED Would may be easier as may be perfect size instead of using CLFs as little bigger I guess
