I use several 4 ft., 4 bulb fixtures. I don't recall ever having to replace a ballast. They last forever. The color spectrum doesn't seem to matter, you're not bringing anything to the flowering stage. Cheap shop lights work fine.

My son uses plastic ceiling lampholders with CFL lights. He mounts them vertically and horizontally. These use about a fourth the energy I use and they work very well.
