Abstract

A circuit is provided for energizing one or more discharge lamps. The circuit is capable of being powered from one or two alternative AC voltage and comprises a transformer having a common first tap, a second tap and a third tap, and a dual voltage means which accepts power from a pair of AC source lines. The dual voltage circuit connects the AC source lines to either the first common first tap and the second tap, if the voltage is at the first AC voltage, or to the common tap and the third tap if the voltage is at the second AC voltage.
