ABSTRACT:
The efficiency of a horizontally operated arc discharge lamp has been found to be substantially improved by the application of a transverse magnetic field. The magnetic field moves the arc downward, away from the upper wall of the lamp envelope. The magnetic field moves the arc so that the outer mantel that otherwise would make contact with side walls of the envelope stand away from the envelope wall. With the arc withdrawn from the wall, less energy is lost in heating the envelope, resulting in more energy be directed to the emission of light.
