Philips Advance LI573-H5 / LI573-H5-IC High-Wattage Metal Halide HID Ignitor Guide
Quick Answer: The Philips Advance LI573-H5 is an oval-case digital/electronic HID ignitor rated for 105°C case temperature operation in high-wattage Pulse-Start Metal Halide (PSMH) ballast circuits. It operates 750W pulse-start metal halide lamps (ANSI Code M149) across SuperCWA magnetic ballast families, supplying maximum wiring distance capabilities up to 15 feet from the ballast to the lamp.
Philips Advance LI573-H5 Overview & Key Features
The LI573-H5 ignitor generates precision high-voltage starting pulses required to ionize and strike arc tubes in high-wattage 750W pulse-start metal halide luminaires across stadium, industrial high-bay, and outdoor floodlight fixtures:
- High-Wattage PSMH Compatibility: Engineered specifically for 750W Pulse-Start Metal Halide lamps (ANSI M149).
- Durable Oval Case Construction: Housed in a heavy-duty oval aluminum case rated for up to 105°C maximum operating case temperature.
- 15-Foot Lead Distance Rating: Provides high-energy starting pulses with an allowable lead distance of up to 15 feet between the ballast and lamp socket.
- SuperCWA Ballast Integration: Matches Philips Advance 71A6402 and 71A6422 750W SuperCWA magnetic ballast families.

Core technical parameters and ballast family cross-references from the official Philips Advance HID Atlas:
| Lamp Wattage | ANSI Code | Circuit Type | Advance Ballast Family | Max. Dist. to Lamp | Case Type |
|---|---|---|---|---|---|
| 750W | M149 | SuperCWA | 71A6402, 71A6422 | 15 ft | Oval (LI573-H5 / LI573-H5-IC) |
Installation & Lead Wire Guidelines
- 3-Lead Connection Scheme: Connect the 12-inch stranded lead wires into the SuperCWA ballast circuit: Red (X1) to the high-voltage lamp socket contact, White (X2) to Common Neutral, and Blue (X3) to the ballast coil tap.
- Lead Wire Distance Limit: Do not exceed the 15-foot maximum wiring distance between the ignitor and lamp socket to prevent ignition pulse voltage drop.
