Hey Tex,
I've got the same tank. I went through the whole light buying process a couple of weeks ago and "settled" on the Custom SeaLife PC with moonlight setup. If I remember correctly it runs at 65w and was told it would be plently of light for what I wanted in my tank. A little added bonus was the hella kewl moonlight doo-hickey... The first night I noticed so my stuff in the tank that it blew my mind. Be advised, the lights are a little pricey, thinking around $270 at a LFS (my guy gave me a little discount, so YMMV).
Good Luck on finding what you want, it seemed there was as many lighting options as there were tank options.
