Best Answer

The ballast is a transformer that steps the voltage up higher than its incoming voltage.

This is usually used with flourescent, metal halide, & sodium vapor lights.

The higher voltage is needed to 'excite' the gases within the bulbs and make the molecules bounce around and give off light.
