YOu could use two 36 inch long Finnex RayII LED lights, in one row across the top of the tank, right on top of the tank, and get about 30-35 micromols of PAR - very good low light.

If you hang the light a foot above the top of the tank you will just about have to use either a custom made LED light or a 4 bulb T5HO light, possibly made for you by Catalina Aquarium. That light would be about 40 inches from the substrate.
