You're not being a jerk that's what this forum is all about, getting your questions answered. The whole watts/gallon thing is just a basic guide and it really depends what you want out of your tank. Fish don't really care what light they have, but all corals do. As a base line about 2 watts/gallon is the start of the basic corals/sponges, and it goes up from there. A good thing to do is check out what you would like to keep first and find out what their needs are. As far as bulbs goes metal halide packs the most punch out there as far as size goes. For example I have a 29G tank that I could fit 3x250W metal halide bulbs over. that's a lot of light.
VHO (very high output) is a type of flourescent that is very high output compared to NO (normal output). For example a VHO tube of the same size as a NO would put out 110W(VHO) vs 30W(NO). They also require special ballasts. VHO is slowly being phased out by PC (power compact).
Full Spectrum tubes probably wouldn't work, as they do the "full spectrum" where the tank only needs the upper to high spectrums. And thus requires tubes that consentrate on the upper spectrums only. For an example a 30W full spectrum is 30W over the entire spectrum while a 30W 10,000K is 30W in that on spectrum.
Hope this helps you out.
