ABSTRACT:
A gas discharge tube (e.g., a lighting tube) comprising two coiled segments is described. The geometry of the coiled segments is such that the angle of the tangent to the center line of the tube with respect to the tube's longitudinal axis gradually increases as one moves upward along the ascending coiled segment, and gradually decreases as one moves down the descending coiled segment.
