Lighting suggestions

Would a 400 watt metal halide with a lumens bright large reflector be enough for a 40x30x25 sps tank?

Normally one would use 2 Halides to cover a 48" tank, your only 8" off of that. I guess if you had it high enough, you could cover alot of space. But I'd say you should probably go with 2 400w Halides for your width and depth.
