ABSTRACT:
A high pressure sodium discharge lamp employs a starting aid allowing the use of increased xenon pressure for higher efficacy. The starting aid is positioned far enough from the ends of the electrodes so that end blackening does not attenuate the starting pulse and render the lamps impossible to start after they have been aged over 100 hours.
