Abstract
Efficient starting of solenoidal electric field discharge lamps is effected when a primary voltage exceeds a critical transition level. A starting potential may be applied to electrodes on the external surface of the lamp which are capacitatively coupled to a fill gas. Alternately, the electrodes may be disposed within the lamp envelope. Optimally, the starting electrodes are disposed along the axis of an annular transformer core at opposite ends of a tunnel region.
