GE 41826 MVR1000/U BT56 1000W Metal Halide E39 Base

The GE Multi-Vapor® 41826 MVR1000U Lamp is an industrial-grade, high-intensity discharge (HID) quartz metal halide bulb engineered for heavy-duty high-bay manufacturing spaces, commercial warehouse distribution centers, parking lot security grids, and outdoor sports stadium frameworks. Delivering an immense 108,000 initial lumens of crisp 4000K cool white light, this high-performance module utilizes a clear, computer-shaped **BT56 hard glass envelope**. Outfitted with a heavy-duty **E39 mogul screw base** and certified for universal burning orientations, it provides a 15,000-hour rated average service life when driven by matching ANSI standard M47 control gear.

ADL Supply Expert Application & Replacement Guide

The GE MVR1000U (41826) lamp is a heavy-duty industrial facility footprint standard specified for retrofitting and maintaining deep high-bay manufacturing spaces, aviation hangars, commercial shipping ports, rail staging hubs, and broad outdoor area security boundaries. Precision crafted with a heavy clear BT56 outer shield glass envelope, it outputs high-intensity visible white light across an extended 15,000-hour service lifespan, helping building engineers reduce overhead relamping cycle costs.

Critical Ballast Core Sizing & Mandatory Enclosed Fixture Protection Rules: This 1000W system operates exclusively when driven by a compatible industry-standard ANSI M47 metal halide ballast circuit. Attempting to spark or drive this high-power module on newer pulse-start ceramic ballasts (M141 tracking loops) or legacy high-pressure sodium control gear will prompt non-ignition, catastrophic arc tube failure, or localized ballast coil fires.

Furthermore, maintenance crews must track the **M47/S industry safety classification rule: the S-rating dictates that this lamp must be operated exclusively inside fully enclosed luminaires outfitted with a tempered glass lens shield**. Open high-bay rings or exposed track canopies are strictly prohibited. In the event of a high-pressure, end-of-life non-passive arc tube rupture, an open-face fixture will drop white-hot quartz fragments ($1000^\circ\text{C}$) straight down onto facility floors, presenting a critical fire and structural hazard. Ensure the 39mm wide E39 Mogul base is threaded securely into its lampholder socket to eliminate high-resistance current arcing loops in high-vibration heavy machinery environments.

Operation, Safety & Mounting Compliance

High-Pressure Strike and Hot Restrike Intermission Windows

Following initial cold system ignition strikes, this quartz metal halide capsule requires an initialization window of 5 to 7 minutes to fully vaporize internal gas elements and settle into its stable 4000K color profile. If a voltage sag or power interruption breaks the circuit track line during operational shifts, a mandatory hot restrike cool-down block of 10 to 15 minutes must be allowed. This lets internal operating arc tube pressures cool down completely before the high-voltage ballast can safely strike the arc loop again.

UV Suppression Warnings and Casing Integrity Maintenance

This lamp can emit harmful shortwave ultraviolet (UV) radiation capable of causing severe skin burns and eye inflammation if the clear BT56 outer glass envelope scratches or micro-cracks during active cycles. National life safety and manufacturing facility codes mandate immediate replacement if the glass integrity is compromised. Never handle the bulb envelope face with bare hands; skin oils create thermal hotspots that cause the hard glass structural walls to thin or micro-fracture early. Relamp using clean cotton gloves, a tech wipe, or original wrap structures.
