Angry has some good advice. You can find what you're looking for at AHSupply at some of the best prices going. They've got just about every kind of CF
lamp you can imagine, in both straight and square pin.
As to color, I'm with Angry again. I like a mix of 6700 and 10000K, but some people consider 10000K too harsh and prefer all 6700K or lower. Ask at your LFS
and they can probably show you some tanks with various sorts of lighting; most likely SW
tanks but you don't have to tell them what you're going to do with the lights :P
Oh, and welcome to AquariumAdvice
Haven't seen you around before. Don't ever hesitate to ask if you have any questions and don't hesitate to post pictures of your tank because we love pics
