 JAMES carried out the American ballast verification and authorized the verification mark that will be affixed to the ballast,High Pressure Sodium and Pulse-Start Metal Halide Lamps High pressure sodium and modern metal halide lamps which include existing lamps, 150W and less, as well as the new generation of pulse-start metal halide lamps, 150W and greater, have no starting electrodes. In addition to an OCV of approximately two times the lamp voltage, these lamps utilize an “ignitor”to provide a high voltage starting pulse directly across the main electrodes. Once the lamp’s arc is established,the ignitor automatically stops delivering pulses, and the lamp comes up to full brightness on its own.
