The Philips Advance e-Vision IMH-70-G-LF is a single-lamp low frequency electronic ballast for 70W metal halide lamps (ANSI M139/M143). It runs on any line voltage from 120V to 277V (50/60 Hz), holds lamp wattage steady for consistent color, and ships with side exit leads with mounting feet. Catalog No. IMH-70-G-LF.

Technical Specifications

Product Overview

Low frequency electronic HID ballasts such as the Philips Advance e-Vision line continuously measure and adjust lamp wattage, which keeps the superior color properties of ceramic metal halide lamps stable over life. That makes e-Vision the preferred choice for applications that were once lit with tungsten halogen or incandescent sources, such as retail lighting.

• Intellivolt 120-277V: one ballast covers 120V, 277V and any voltage in between, so you stock fewer part numbers.
• Constant lamp wattage: lamp wattage changes less than 0.5% with a +/-10% change in line voltage, for stable color from lamp to lamp.
• Low frequency, square wave output: prevents acoustic resonance in the arc tube and helps maximize lamp life.
• Built-in protection: thermally protected, internally fused and output short circuit protected, with lamp end-of-life shutdown.
• Compact metallic enclosure: smaller and lighter than magnetic HID ballasts, with better heat transfer.
• Sound rated A, power factor above 0.9, ballast factor 1.0: quiet, efficient and delivers full rated lamp output.

Compatible Applications

• Retail display and accent lighting in track fixtures and downlights
• Lobbies and atriums
• Landscape and façade lighting

Before Ordering

• Lamp: confirm the lamp is 70W metal halide lamps (ANSI M139/M143).
• Lead exit: this is the LF version (side exit leads with mounting feet); the BLS version is a separate catalog number.
• Voltage: Intellivolt accepts 120V through 277V at 50/60 Hz.
• Fit: case G, 3.8" x 3.0" x 1.2" (L x W x H).
• Lamp distance: keep the ballast within 5 ft of the lamp.

Safety and Handling

• Disconnect power before installing or servicing, and have the work done by a qualified electrician.
• The ballast case must be grounded; connect the green lead to the fixture ground.
• Lead functions: black and white are input power, red is lamp base, blue is lamp screwshell, green is ground.
• Do not exceed the 90°C maximum case temperature; excess heat shortens life and can trip the resettable thermal protector.
• With screw-base lamps, connect the red lead to the center terminal of the lamp socket.
• The ballast output shuts down after 20 minutes if the lamp fails to ignite.
• Cycle power off, then on, after replacing a lamp.

Compliance

• Thermally protected (resettable), internally fused and output short circuit protected, with lamp end-of-life shutdown.
• Sound rated A; power factor above 0.9; maximum harmonic distortion 15%.
• Confirm listing marks on the ballast label before specifying.
