GE Multi-Vapor® Quartz 47760 (MVR175U-ED28) Metal Halide Lamp — 175W | 4000K Cool White | 13,600 Lumens | Enclosed Fixture Rated

The GE Multi-Vapor® Quartz 47760 (MVR175U-ED28) Lamp is an industrial-grade, high-intensity discharge (HID) quartz metal halide bulb engineered for warehouse high-bay fixtures, manufacturing plant assemblies, commercial security floodlights, and outdoor area parking perimeters. Delivering 13,600 initial lumens of neutral 4000K cool white illumination, this 175-watt workhorse utilizes a traditional probe-start layout to achieve reliable commercial brightness. Outfitted with a heavy-duty E39 mogul screw base and a robust ED28 hard glass envelope, it features a universal burning position for flexible mounting in any orientation on standard ANSI M57 electrical ballast tracks.

ADL Supply Expert Application & Replacement Guide

The GE Multi-Vapor® 175W ED28 quartz lamp is an established industrial facility maintenance baseline specified heavily for legacy high-ceiling troffers, warehouse loading docks, manufacturing floors, and regional outdoor security parameters. Delivering an energy-efficient 66 lumens per watt baseline output, this high-intensity quartz discharge lamp provides strong, long-lasting lumen maintenance across its standard service life cycle, making it a highly cost-effective relamping solution for commercial electrical installations.

Critical ANSI M57/E Enclosed Fixture Ratings and Arc Voltage Parameters: Facility electricians and commercial maintenance teams executing routine site upgrades must analyze current fixture parameters prior to checkout: this lamp carries a strict ANSI M57/E code rating, certifying it exclusively for Enclosed Luminaire installation fields. The "/E" suffix establishes that this quartz discharge capsule must operate behind a enclosed tempered glass containment lens capable of holding hot fragments in the rare event of an end-of-life arc tube rupture.

Additionally, this bulb operates at a continuous ballast-regulated **arc voltage of 132V AC with a running current draw of 1.50 Amperes**. Attempting to connect this bulb directly to unballasted line voltage, or running it on incorrect ballast formats like ANSI M58, M137, or pulse-start circuits, will destabilize the gaseous columns, causing rapid cathode failure or immediate arc tube fracturing.

Operation, Safety & Mounting Compliance

High-Frequency Harmonic Protection and Thermal Bounds

This traditional probe-start linear lamp interfaces with standard core-and-coil magnetic ballast assemblies tuned to industrial line frequencies. It incorporates an automated protection path when linked to approved control gear, isolating line ripples from degrading internal quartz structural pathways. The high internal gas pressures require that maximum operating temperatures are observed, preventing premature arc tube clouding and securing stable lumen efficacy across the bulb's lifespan.

Low-Mercury Vapor Dosing and Safe Bulk Recycling Protocols

This high-intensity metal halide lamp incorporates a metered heavy-metal mercury fill dose (limited to 23.0 mg total weight) combined with an eco-conscious picogram threshold (293 pg/mean lumen-hr). While fully compliant with standard commercial building metrics, the presence of mercury vapor dictates that spent lamps must be securely processed through certified regional commercial bulk recycling repositories during facility maintenance change-out sweeps rather than discarded into standard municipal solid waste streams or common landfills.
