Frag Tank Lighting?

[badfish]

im in the process of building a 40 bdr frag tank.i have a 250 watt se halide with a mini lumen bright reflector.it runs on a coralvue dimmable ballast.
i will has a mix of lps and sps and a few zoas and palys.
which bulb do you guys think would give me the best color and growth?

I use 10k XMs for my frag tank. They work great, and they have high PAR so i can raise the light fixture high enough to get more light spread on the sides.
