ABSTRACT:
An AC operated glow lamp having a cathode electrode and a pair of anode electrodes driven from a capacitively ballasted autotransformer that provides phase inversion so as to enable a full wave rectification of the discharge current thus operating in a DC regime from an AC line. The double anode lamp and ballast circuitry provides for rapid lamp starting as well as continuous cathode heating during lamp operation.
