PHILIPS ADVANCE LI-533-H4-IC | 50W-450W Metal Halide Ignitor | 105°C

Philips Advance LI-533-H4-IC is a high-performance electronic ignitor designed for pulse-start metal halide systems ranging from 50W to 450W. This critical component provides the high-voltage pulse necessary to strike the arc in HID lamps, ensuring reliable and consistent ignition. Housed in a durable black round case and rated for continuous operation at temperatures up to 105°C, it is built to withstand the demanding thermal environments of industrial and commercial luminaires. This ignitor comes complete with a CC-125 mounting clamp for secure installation and is proudly assembled in the USA to meet rigorous quality standards.

Product Overview

The Philips Advance LI533H4IC is a precision-engineered ignitor required for the proper starting of pulse-start Metal Halide lamps. Unlike probe-start systems, pulse-start ballasts rely on this external ignitor to deliver a specific voltage spike (typically 3kV to 5kV) to ionize the gas within the arc tube. Its compact 2-inch length allows for easy integration into existing ballast cans or fixture junction boxes. By supporting a wide range of ANSI codes, this ignitor serves as a versatile replacement component for maintenance professionals managing diverse HID lighting layouts.

• Reliable Lamp Ignition: Ensures immediate striking of the lamp arc, reducing stress on the ballast and extending system life.
• High Thermal Tolerance: Rated for 105°C continuous operation, making it ideal for high-bay and area lighting fixtures where heat dissipation is a factor.
• Broad Compatibility: Supports a vast array of ANSI pulse-start codes, providing a "one-stop" solution for various metal halide wattages.
• Secure Installation: The included CC-125 mounting clamp ensures the ignitor remains firmly seated, even in high-vibration industrial settings.
