a little more info would be nice(how many lights, ballast, watts) but if you just using one light(wattage doesn't matter imo), then you'll use the 120, I'm going to assume that you are running the wire straight from your ballast to a standard house electrical outlet, then you'll definetly use 120v, because your typical house only runs on 120v. Hope this helped, if it didn't then post back with seom more info and we can go from there.

120volts vs. 240 volts:
120 has your standard three prong, while 240 will have a 4 prong plug that locks into place, 240v is what your washer/dryer hooks up two, so any applience/machinery/ high wattage light system should be run on 240. So 240 is able to handle more watts, due to more volts, and there will be more amps in there to.

In the USA the normal power in houses etc. is running at a voltage of 120 volts.. in the UK it's 240 (Europe 230). The ballast transforms the voltage to a voltage suitable for the bulb, if you were to connect your 120v household power to the 240 volt windings on the ballast the bulb would only receive half of the voltage it's supposed to.. this would be bad. If you were in Europe you'd use the 240 volt windings.
