Description

Compatible with any Philips Advance Reactor (R), High-Reactance (HX), and Constant Wattage Autotransformer (CWA) ballast and ignitor circuit that includes a 120V input tap, the Philips Advance shut-off device (LISODTM) enhances the reliability of High Intensity Discharge (HID) lighting systems where ignitors are utilized to start the HID lamps. This includes all high-pressure sodium lamps as well as all low, medium, and high wattage pulse-start metal halide lamps. The LISOD shut-off device is used in addition to a standard ignitor. The LISOD shut-off device increases the life of the ignitor by disabling it from the circuit and eliminating any concern overlong-term ballast reliability due to continuously pulsing ignitors when a lamp is burned out.
