GE 41826 MVR1000/U – 1000W Multi-Vapor Metal Halide Lamp | 4000K | 108,000 Lumens | BT56 | E39 Mogul Base

The GE 41826 MVR1000/U is a 1000-watt Multi-Vapor quartz metal-halide HID lamp with a clear BT56 hard-glass envelope and E39 mogul screw base. It produces 108,000 initial lumens at 4000K with a CRI of 65 and has a nominal 15,000-hour rated life. The lamp uses a universal burn position, but its S-rated safety classification limits open-fixture use to vertical base-up or base-down operation within ±15 degrees. Please verify the exact GE product code, lamp designation, ballast ANSI compatibility, fixture enclosure, burn position, dimensions, and electrical requirements before ordering.

Product Overview

The GE 41826 MVR1000/U is a high-output quartz metal-halide lamp designed for compatible 1000-watt HID lighting systems. Its clear BT56 envelope, concentrated arc source, and 108,000-lumen initial output make it suitable for large commercial, industrial, sports, warehouse, and outdoor-area luminaires engineered for this exact lamp class.

The lamp provides 4000K cool-white illumination with a CRI of 65. Mean light output is listed at 86,000 lumens, supporting high-output maintenance applications where existing GE MVR1000/U lamps or equivalent ANSI-compatible systems are already installed.

This lamp requires a properly rated metal-halide ballast and must not be connected directly to line voltage. Lamp wattage alone is not sufficient to establish compatibility; the ballast ANSI code, open-circuit voltage, fixture enclosure, base type, dimensions, and operating position must all be verified before installation.

Compatible Applications

Industrial high-bay lighting
Warehouses and distribution facilities
Manufacturing plants
Large commercial interiors
Sports and stadium lighting
Parking lots and exterior area lighting
Airport, transportation, and large-site illumination
Maintenance replacement where GE product code 41826 or MVR1000/U is specified

Before Ordering – Verify

GE product code: Confirm product number 41826.
Lamp designation: Verify MVR1000/U.
Wattage: Confirm the fixture and ballast are designed for a 1000W metal-halide lamp.
Ballast: Match the lamp ANSI requirements to the code printed on the ballast or luminaire label.
Base: Confirm the fixture uses an E39 mogul screw lampholder.
Bulb shape: Verify the fixture accepts a BT56 lamp approximately 15.37 inches long and 7 inches in diameter.
Burn position: The lamp itself is rated for universal operation, but open-fixture use is restricted by the S-rating.
Open fixtures: Use only in vertical base-up or base-down operation within ±15 degrees.
Horizontal or angled operation: Use an enclosed luminaire with a lens or diffuser capable of containing hot quartz or glass fragments.
Outdoor use: Do not expose the lamp directly to water. Outdoor installations require an appropriately enclosed fixture.
Rated life: Relamp at or before 15,000 hours to reduce the risk of rupture and declining light output.
Weekly shutdown: GE instructs that the lamp be turned off for at least 15 minutes once per week.
Dimming: Contact the manufacturer and follow the approved system instructions before operating on a dimming system.
Packaging: One lamp per each and six lamps per standard case.

Safety and Handling Guidelines

Disconnect and lock out electrical power before inspection, installation, maintenance, or removal.
Use only with a properly rated metal-halide ballast and compatible fixture.
Do not connect the lamp directly to line voltage.
Do not exceed the rated voltage or ballast operating parameters.
Wear safety glasses and gloves when handling the lamp.
Do not use excessive force when threading the lamp into the E39 socket.
Do not install a lamp with scratched, cracked, punctured, or broken outer glass.
A damaged outer envelope may permit hazardous shortwave ultraviolet radiation that can cause skin burns and eye inflammation.
Turn off power immediately if the outer glass is broken, then remove and dispose of the lamp safely.
Allow the lamp and fixture to cool before handling.
Do not stare directly at the operating light source.
Keep combustible materials away from the lamp and fixture.
Do not use where directly exposed to water.
Relamp at or before the end of rated life.
Use only in the permitted operating position and enclosure configuration.
Operate in luminaires complying with applicable UL or IEC fixture standards.

Compliance

S-rated lamp with restricted open-fixture operation.
Open-fixture use is permitted only in vertical base-up or base-down operation within ±15 degrees.
Other operating positions require an enclosed luminaire capable of containing hot lamp fragments.
The lamp contains mercury and must be managed according to applicable disposal and recycling laws.
No RoHS, ETL, DLC, ENERGY STAR, Title 20, Title 24, or JA8 claim is identified in the supplied GE product datasheet.
