You just need 2 of the RB Photon V2 or Aquasanrise 32" fixtures.
You might also look at ReeFi-Lab pendants.

It's a new fixture. I bought one a few months ago just to try and my frag tank LOVES it! All Cree leds, 150 watts, only $300 each, way more blue than white leds, crazy software control (even for the fan)! They even use a single, real glass lens whic allows 2'x2' to 3'x3' coverage in a 24" deep tank. Two would work and three would grow anything with great coverage.
