Lighting recommendations

[rocketlily]

I'm having a new tank built. Corner tank with 40" back sides (diamond shapped) with a depth of approx 28" (back to front) and 20" deep. There will not be any way to mount lights on top due to the shape, so I'm going to have a light stand built into the frame (or possibly a special frame for the top of the tank). Obviously, due to the cost of the tank, I hope I am only doing this once. This will be a reef tank, but not sure of the corals I want to put in, but do not want to be limited due to a poor choice of lighting.

Any suggestions as to what lights I should buy? (with the exceptions of LED's)
