Question: What determines the light output of the flourescent, the bulb or the basllast?

Both really. The ballast used determines how much power is put through the lamp (ie wattage). The quality of the lamp can also affect light output and longevity.

Yes if you put an NO on a VHO ballast, the ballast will 'overdrive' the lamp to VHO levels. However, if I recall correctly, Icecaps don't produce the full 110W. Its something like 65W but with a higher frequency.

No. If you wire the lamps as per their recommended configuration it should run at the 65W (or whatever it actually is).

I suppose it is possible but my first guess would be the steep output drop off of fluorescent lamps. It is not uncommon to see fluorescents lose their out of the box intensity in only a few weeks yet alone a few months.
