PHILIPS ADVANCE e-Vision 70W Electronic HID Ballast | 120V-277V | M98/M139

Philips Advance e-Vision IMH-70-G-LF (IMHG70LFM) is a high-performance electronic ballast designed to operate a single 70W Metal Halide lamp (ANSI M98 or M139). Featuring IntelliVolt technology, this ballast automatically detects and operates on any voltage from 120V to 277V. The "LF" configuration includes a durable metal housing with mounting feet and side-exit leads, providing superior heat transfer and simplified installation for commercial downlights and track fixtures.

Product Overview

The Philips Advance e-Vision line represents the pinnacle of HID ballast technology. By utilizing electronic circuitry instead of traditional copper-and-iron cores, the IMH-70-G-LF provides significantly better lumen maintenance and energy efficiency. It features End-of-Life (EOL) detection, which safely removes power if a lamp behaves erratically, preventing thermal stress and the annoying "cycling" common in older HID systems. Its compact metal enclosure ensures maximum durability and better heat dissipation compared to plastic alternatives.

• IntelliVolt Technology: Operates on any input voltage from 120V to 277V (50/60Hz) for maximum job site flexibility.
• Superior Safety: Includes resettable thermal protection and automatic shutdown after 20 minutes if a lamp fails to ignite.
• Quiet Operation: Sound rated 'A', making it suitable for quiet indoor environments like offices, galleries, and retail stores.
• Efficient Design: High power factor (>0.9) with a 1.0 ballast factor ensures the lamp receives full rated power with minimal energy waste.
