Product Overview

The Philips Advance E-Vision IMH-P39-G-LF (Catalog No. IMH-P39-G-LF) delivers reliable, feature-rich electronic ballast performance for 35-39W pulse-start ceramic metal halide lamps. This LF-series ballast supports ANSI C179 and M179 lamp codes with Intellivolt 120-277V auto-ranging input, eliminating voltage selection errors and simplifying inventory management across commercial facilities.

Engineered for professional installations, this replacement ballast features integrated end-of-life (EOL) detection that removes power from lamps when they behave erratically or fail to ignite — preventing hazardous lamp cycling and enhancing fixture safety. Resettable thermal protection and a robust aluminum housing provide superior heat transfer and durability compared to plastic-encased alternatives. With high power factor (>0.9) and efficient electronic operation, this ballast delivers quiet, energy-conscious performance in retail, hospitality, and commercial lighting applications.

The LF configuration includes side-exit leads and integrated mounting feet for streamlined installation in track heads, recessed fixtures, pendant systems, and architectural lighting applications. Compatible with ceramic metal halide lamps requiring C179 or M179 pulse-start ballasts, this unit supports flexible specification across boutique retail, galleries, showrooms, and upscale commercial environments.

Why Choose This Product

• Intellivolt 120-277V auto-ranging: Universal input voltage eliminates selection errors and simplifies inventory — one ballast fits multiple facility voltage configurations.
• EOL detection safety feature: Automatically removes power from erratic or failed lamps — prevents hazardous lamp cycling and enhances fixture safety in occupied spaces.
• Resettable thermal protection: Protects ballast from overheating — automatically resets after cool-down, reducing service calls and replacement costs.
• Aluminum housing construction: Superior heat transfer and durability compared to plastic-encased ballasts — enhances reliability in demanding commercial applications.
• High power factor (>0.9): Efficient power utilization reduces electrical demand and supports energy-conscious facility management.
• Ballast factor 1.0: Delivers rated lamp lumens without over- or under-driving — ensures consistent light output and lamp life.
• LF series with side exit leads: Streamlined installation in track, recessed, and pendant fixtures with integrated mounting feet and 9-inch leads.
• Wide temperature operation: Starts reliably down to -20°C / -4°F — suitable for unheated warehouses, outdoor fixtures, and cold-storage applications.
• Dual ANSI compatibility (C179/M179): Supports both ceramic metal halide lamp codes — broader application flexibility than single-code ballasts.
• Auto-shutdown safety: Ballast output shuts down after 20 minutes if lamp fails to ignite — prevents energy waste and component stress.

Technical Specifications

Applications

Installation & Compatibility Notes

Confirm the following before installing this Philips Advance E-Vision IMH-P39-G-LF ballast:

• Lamp compatibility — ANSI C179 or M179: Verify the installed lamp carries C179 or M179 ANSI designation for 35-39W pulse-start ceramic metal halide. Do not install with incompatible lamp codes.
• Input voltage — Intellivolt 120-277V: Auto-ranging input accepts 120V or 277V (50/60Hz) — verify facility voltage before installation.
• Maximum case temperature: 90°C — ensure adequate fixture ventilation to prevent thermal shutdown.
• Maximum distance to lamp: 5 feet — position ballast within specified lead length for reliable ignition.
• Lead connection: Connect the red lead to the center terminal of screw-base lamps (E26/E39) for proper polarity. For PGJ5 or other bi-pin bases, follow lamp-specific wiring diagrams.
• Lamp failure response: Ballast will shutdown after 20 minutes if lamp fails to ignite — cycle power off/on after lamp replacement to reset.
• EOL detection: Ballast removes power from lamps that behave erratically or reach end-of-life — replace lamp and cycle power to restore operation.
• Power cycling: Always cycle power off, then on, after replacing the lamp to ensure proper ballast initialization.
