Choice Lighting issues

I am very inexperienced as far as growing marijuana is concerned..

However, I am interested in starting two plants in my closet.

Money isn't exactly too much of an issue, but I don't want to spend an exuberant amount of cash on lights that are too powerful for a couple of plants.

I'm fine with switching light sources depends on the stage of growth, but I'm confused about how much light and what type of light I actually need.

Also, I don't want to use lights that will produce too much heat, given the small space.

Are fluorescents appropriate for seedlings?

The seeds are close to sprouting..
So any information is super helpful!

Uh.. Hm. I forgot to mention the closet size. How convenient..

It's approximately 2ft deep, 4.5 feet wide, and 6 feet tall.
