Lighting for sump

[Jaws]

I'm going to be purchasing a bulb to light my sump very soon and I was wondering what lighting is reccommended. I know mostly everyone uses normal output lights but my sump will also have a refugium at one end of it. The entire sump/refugium will be about 5 feet long by 18" wide and 18" high. I would like about 24" of that length to be the refugium. I planned on getting a 48" 110W VHO White actinic bulb for this purpose. Any reason why I shouldn't?
