propagation tank ideas

[Jaws]

Sorry to hijack but what bulb, other than metal halide, could be used to grow sps if they're close to the top? I'm setting up a 24 by 24 by 18" deep refugium that will be divided in to two sections: one section for macro and the other section for sps frags. Right now I've got a Coralife 150W clip-on pendant but I would prefer to use that on a 33G LPS/Softie tank that I'm setting up. Thanks, and sorry to hijack again.
