Its in my canopy, I would say the bulb is about 6 inches from the water. I think a RBTA would be the only thing that would need high light. I may add some rics, sun coral but those don't need light really, some acans, and one acropora maybe.

Here is my tank right now

Here is my tank so far.. Right now I have: Candy Canes, Xenia, Mushrooms, Montipora Digitata, some zoas.
