GE 78629 GE432MV-H

The GE UltraMax® High Output Series 78629 (GE432MV-H) Ballast is a commercial-grade, multi-voltage electronic control gear module engineered to operate three or four standard or energy-saving T8 linear fluorescent lamps. Designed for universal 120–277V systems, this high-performance ballast utilizes optimized Instant Start technology to deliver immediate, flicker-free ignition while maximizing system light levels. Outfitted with an active power factor correction circuit, anti-striation control to eliminate visual tube rolling, and independent parallel lamp operational paths, this high ballast factor (1.18 BF) module serves as the premier solution for commercial high-bays, retail supermarkets, manufacturing plants, gymnasiums, and warehouse facility maintenance sweeps.

ADL Supply Expert Application & Replacement Guide

The GE UltraMax 78629 control gear is a high-intensity commercial facility footprint standard specified heavily by electrical contractors, real estate estimation teams, and industrial property maintenance divisions. Operating with an optimized high-frequency solid-state framework, this module delivers maximum light extraction across standard systems, yielding 15% to 20% more lumens compared to standard-output 0.87 BF alternatives. This enables facilities to reduce the total number of physical troffers or bulb counts needed to cross specific high-ceiling or warehouse footcandle design benchmarks, slitting installation and material overhead costs.

Critical Shunted Lampholder Mandate & Parallel Circuit Boundaries: Field electricians executing routine facility lighting swaps must evaluate socket configurations closely prior to termination: this Instant Start electronic ballast requires shunted lampholders at all terminal connection points. Shunted sockets incorporate an internal metal bridge that joins the left and right pin tracks, allowing the ballast to send its immediate high-voltage strike slice across the gas column cleanly. Inserting an Instant Start ballast into un-shunted sockets (common in Programmed Start fixtures) will break the output pathway, causing ignition failure, high-resistance arc faults, or immediate terminal component damage.

Furthermore, this module utilizes a premium Parallel Lamp Operational architecture. Unlike legacy series-wired ballasts where a single filament blowout kills the entire fixture loop, this control gear operates independent channels. If a single lamp drops out inside a 4-lamp layout, the remaining tubes continue to burn at full high-output efficacy, dramatically slashing operational labor tracking costs by allowing maintenance teams to structure routine group re-lamping sweeps.

Operation, Safety & Mounting Compliance

High-Frequency Electronic Signal Transformation

This electronic assembly converts raw municipal alternating current into high-frequency ballast outputs exceeding 42 kHz, completely eliminating stroboscopic workplace eye fatigue and structural flickering loops common in old low-frequency magnetic systems. It incorporates an automated active anti-striation control loop containing micro-choke filters that stop visual tube rolling/shimmering across energy-saving lamp filaments.
