Philips Advance LI501-J4 / LI501-J4-IC Long-Range High Pressure Sodium HID Ignitor Guide
Quick Answer: The Philips Advance LI501-J4 (and individually cartoned as replacement kit LI501-J4-IC) is a long-range round-case electronic HID ignitor rated for 105°C case temperature operation in High Pressure Sodium (HPS) ballast circuits. Unlike standard short-range ignitors (limited to 2 feet), the LI501-J4 generates high-energy ignition pulses capable of driving HPS lamps at remote mounting distances of 15 to 50 feet from the ballast.
Philips Advance LI501-J4 Overview & Key Features
The LI501-J4 long-range ignitor enables remote ballast mounting configurations across high-mast lighting, athletic fields, hazardous locations, and architectural applications where ballasts are placed far from the lamp fixtures:
- Extended Remote Mounting Capability: Overcomes wiring capacitance to deliver reliable starting pulses at distances up to 35 to 50 feet from the ballast enclosure.
- High Pressure Sodium Compatibility: Designed for medium-to-high wattage HPS systems including 35W (S76), 50W (S68), 70W (S62), 100W (S54), 150W (S55), 200W (S66), 250W (S50), 310W (S67), and 400W (S51) lamps.
- Standard Round Potted Construction: Features a durable round aluminum housing (1.3" diameter x 2.5" height) rated for 105°C case operation, complete with 12-inch lead wires.
- Individual Carton Packaging (-IC): The LI501-J4-IC variant comes individually packaged with the standard RW33CC1252 round-case mounting clip included.

| 150W | S55 / S56 | HX / CWA / R | LI501-H4-IC / LI551-H4-IC | LI501-J4-IC (15 ft – 50 ft) |
| 200W – 250W | S66 / S50 | CWA / Reactor | LI501-H4-IC | LI501-J4-IC (50 ft Max) |
| 310W – 400W | S67 / S51 | CWA / Reactor | LI501-H4-IC | LI501-J4-IC (50 ft Max) |
Wiring & Remote Mounting Guidelines
- 3-Lead Wire Color Codes: Connect the 12-inch lead wires directly to the ballast circuit: Red (X1) to Lamp socket lead, White (X2) to Common Neutral, and Blue (X3) to the ballast tap.
- Remote Wiring Distance: Ensures proper ignition pulse delivery across wire runs between 15 feet and 50 feet. Do not exceed 50 feet total wire length to prevent excessive pulse voltage drop.
- Mounting Clip Included: Individual carton units (LI501-J4-IC) include the RW33CC1252 round mounting clip for secure fastening.
Frequently Asked Questions
What is the difference between LI501-H4-IC and LI501-J4-IC?
The standard LI501-H4-IC ignitor is designed for ballasts mounted within 2 feet of the lamp, whereas the LI501-J4-IC is a long-range ignitor designed for remote ballast applications up to 50 feet from the lamp.
When should I use a long-range ignitor?
Use a long-range ignitor like the LI501-J4 when the ballast cabinet is located remotely at ground level or in an accessible electrical room, requiring long wire runs up to poles or ceiling-mounted fixtures.
Can LI501-J4 be used with Pulse-Start Metal Halide lamps?
No. The LI501 series is engineered specifically for High Pressure Sodium (HPS) systems. For pulse-start metal halide remote applications, use the XTENZA LI533-LR series ignitor.
