Abstract
A beam mode lamp has two discharge electrodes which alternately function as anode and cathode. One or more modifying electrodes are located between the discharge electrodes. Each modifying electrode is kept equal to or negative with respect to the cathode, raising the operating voltage of the lamp from a normal 20 volts to line voltage.
