Well, I decided to bite the wallet and go with 150W Radiums on a BlueWave ballast.
Review: Bluewave ballast VII runs great, not scalding hot if accidently touched.
Lighting: the 2 150W Radiums as the only light over our 30 inch deep mixed tank seems to be doing great. The SPS up top is coloring up so nicely, and have seen growth on it, so its not totally stopped, and the LPS that we had had are coloring up to, from the bleeching out they were doing under the to bright light we had them under, and our mushrooms and zoas at the bottom just seem to be loving it.
So all I can say is I am loving only running the one set of lights.
