Flourescent lights, what do we need to know?

Hey all, I realized I don't have a lot of posts here so I've got a question about fluors.
Basically what exactly are we looking for when selecting lights? Obviously there is size, watts, and there is the types T8, T12 ect
From my quick search on wiki, the T types seem to be ideal heat ranges T8-25 wheres the degrees symbol... which is 77f. T5-35 (95f)

I have specifics of what I want to know, but I'm sure I can figure it out if I have good info, and this thread will help more people if we keep it to general info instead of application specific.
Thanks in advance, hopefully this helps everyone.

I don't think this helps anyone. What are you talking about? Is there a question in here somewhere?

lol no joke

Yea this isn't helping anyone.
100W minimum per plant. 6500K for veg (24 hours a day), and 2700K for flower (12 hours a day), just use CFL's instead of those T's.
lol, we need specifics to actually help, or an actual question to be able to answer... Anyways I hope this does answer your "question" ???
