A 2 foot cube should hold roughly 60 US gallons.  A depth of 2' is gonna be
hard to get much intensity at the bottom.  Have you considered using a 175W
metal halide light?  But back to your question, I don't know much about VHO
but I think the lamps in 2' length are rated 75W.  So you would need 3,
because they are not very efficient.  Instead, I would probably try about
three or four 40W or 50W or 55W "PL-L" compact fluorescents, a.k.a. "high
lumen Biax" or "Dulux L".  If you use the 22.5" 40W PL-L, you can run them off
a F32T8 or F40T8 ballast, although it probably won't be a UL approved
combination.  I just kludged one for my 20H tank with a high ballast factor T8
ballast and it is quite bright.  Ought to be much better once I give it a
proper reflector.  

I can't help you much with web sites cuz I don't know what you are looking
for.  Try searching for (+VHO & aq*) in INFOSEEK and see what you get.
