Watts Per Gallon, Is there too much?

I'm going to be purchasing a new light next week, but I'm thinking ahead since I'd like to use it on a 55g in the future. The new light will be going on my 29g for now until I get the 55g set up in a few months. Anyway, it's going to be a MH with either T5's or PC's. One setup I'm looking at is a 178w fixture(150wMH and (2)14wT5's) and the other is 380w fixture(250wMH and (2)65wPC's). The 178w will give me 6.1 watts per gallon and the 380w will give me 13.1 watts per gallon. I know that when I upgrade to the 55g I'll have to get another light if I go w/ the 178w fixture. The 380w fixture is only $89 more so I'm thinking about going w/ that, but I'm not sure if it will be too much for the smaller tank.:grumble:
