In its simplest form, a ballast uses magnetic energy that erupts into the lamp when it is turned on, stimulating the electrodes to make a current and the lamp glows. Today's fluorescent ballasts are mainly electronic, and they have a number of positive attributes including energy efficiency, reduced flicker of light, and even dimming capabilities.

Ballasts that can operate more than one type of lamp (e.g., the 40-watt F40 ballast can operate either 40-watt F40T12, 34-watt F40T12, or 40-watt F40T10 lamps) will generally have a different ballast factor for each combination (e.g., 95%, <95%, and >95%, respectively). Ballast factor is not a measure of energy efficiency.
