Abstract
An AC discharge lamp having a constricted arc, and powered through a unidirectional ballast with a unidirectional current, is described. The AC lamp operates as a DC lamp. One method of achieving the constriction of the arc of this lamp is to modulate the DC input power to the discharge lamp to reduce the adverse effects of DC operation. The mechanism mixes the chemicals with an acoustically induced flow.
