Need Help With My First Grow General Questions!!!

I recently made a hydro grow set up like this.

I have only 4 holes in my setup. I was wondering what size light I would use for best results.

I was thinking about this cfl linked below and a high rise reflector also on this page

the cfl is 200 watt and says it is a comparison to 600 watt.
