Please do not repost the same topic twice. I'll delete the other thread you started. Stick to this one please. 
As for your question, incandescent and those screw-in CF's are inadequate for lighting planted tanks. What you need are power compacts, as Sir Blackhole recommended. Although, T5's are a better choice, but bulb choice availability is limited in the US. For PC lighting, you can go with retrofits from AHSupply, but this requires a canopy or the use of the enclosures they sell on their site. Remember a piece of glass MUST be used between the glass and the water. Another choice, would be the all-in-one hoods sold by Coralife and JBJ, but I recommend you stick with Coralife. IMO, these are ideal lighting options since they do come with built-in fans, acrylic cover(no risk of cracking), the bulbs, and some even have built-in Moonlites. But of course their ballast and reflector quality is no where near AHSupply's.
