Coralline Growth & Lighting

[TheReefGeek]

I am setting up a Coralline growth tank. (To cure and grow Coralline on the dry rock I sell)

My question is, what lighting should I use?

I know that different coralline grows best under different lighting conditions, but I was hoping some people could post pics of their coralline covered rocks, and report what lighting they are using, especially if you have "crazy" coralline growth.
