It doesn't matter what type of lights you use you will be able to grow just about anything, as long as you have enough of it.

Yes, I've seen many examples of this. Not sure on your tank size but 4 t5 bulbs with good reflectors will allow you to grow pretyy much anything. More would be better though of course.
I'm not to informed with the way lights work myself, but I know when your looking into lights the amounts of watts isn't what you should look at, it's the PAR that's most important. I don't know what that is TBH (if someone could explain that would be tops) but T5's have a better PAR than VHO, which makes them more appropriate for reef tanks (even though VHO has more watts).
Anyway I found most of this information under a google search of T5's vs VHO. It seems most people thought T5's would be the better option.
