'Digital' ballasts are effectively PWM (pulse-width modulated) power supplies, on principles similar to your PC's power supply. They control their output voltage with a feedback loop, not a transformer. This makes them 'voltage agile.' Most can run on any AC voltage from 100-250V, automatically sensing the line voltage.
However, they will draw the same number of watts from the AC mains whether running on 110, 220 or 240. A given 1000W electronic ballast might draw about 1100 watts- that's 4.6A from a 240V line but will draw 10A from a 110V line.
