PHILIPS 132100 HID Ballast Kit Magnetic HID PULSE Start 1 Lamps 70 W S62 High Pressure Sodium Lamps S62 120 V,

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 twotimes 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.
