Lighting options for a 55 Gallon

[acei]

I'm planning on converting my 55 gallon tank to a reef tank. My dealer is making me a damn good deal on Coralife's Aqualight pro. Here are the specs on the light. He's offered it to me for $550. My question is this. Although it's a good price for this light, is it overkill on the 55 gallon tank? It's almost 9W/gallon.

I've never used MH bulbs before and a little concerned about the heat outpput. This system comes with mounting legs, but I can spend a few extra bucks and get the setup that suspends fromt he ceiling. Things I've read have suggested that with MH's I need to have them at least 12 inches above the water surface to keep from heating the water too much, is this accurate. If so I guess I need the suspension kit. What are your thoughts. Can I get away with a cheaper light system and still be able to include SPS's and anenomes in my tank?

I would say that it is a great light if your looking to have an SPS dominated tank, with maybe some clams and possibly some lps, and zoas. Overkill if you want shrooms, leathers, and softies. 6 - 9 inches is what is recommended by most (mine are 6" on one tank and about 7 on the other). I would hang it if you can one of mine is in a canopy and I hate that, the other tank has a homemade pendent that is awesome can move it up if you need to fro whatever reason.

Thanks for the help johnanddawn. It sounds like this light is exactly what I need. My plans involve mostly SPS's, a few LPS's, and a few Zoa's to fill in. Maybe a clam or two (still haven't decided).
