Abstract: A constricted arc-discharge device having means for physically rotating the arc-tube about the longitudinal axis of the arc-tube to stabilize and maintain the constricted arc proximate the longitudinal axis of the arc tube. This device thereby avoids problems caused by arc bowing of the constricted arc-discharge. The device operates with a discharge sustaining filling comprising mercury and metallic halide and provides an extremely efficient source of visible radiation.

Abstract: A combination comprising a constricted arc-discharge device having electromagnetic means associated therewith to rotatably direct a resultant magnetic flux generally transverse to and intersecting the constricted arc-discharge maintained during operation. The magnetic flux interacts with the constricted arcdischarge causing it to rotate about the longitudinal axis of the arc-tube. The luminous efficiency of the combination is very high, and the rotation of the discharge prevents early failure of the device.
