Product Overview

The GE MVR1000/VBU/HO is a 1000-watt High Output / Extra High Output Multi-Vapor® metal halide lamp finished in clear glass, rated at 65 CRI and 3800K color temperature. It ships with a BT56 bulb envelope on a E39 Mogul Screw base and is built to operate on a M47 ANSI-type metal halide ballast.

This High Output / Extra High Output variant is built for higher lumen output at the same or similar wattage class as the standard Multi-Vapor lamp, making it suited to larger high-bay, parking structure, and wide-area lighting applications where maximum light output per fixture matters.

At 15,000 hours rated life and 111,000 initial lumens, this lamp is intended as a like-for-like replacement for GE order code 44835 — confirm the code printed on your existing lamp or fixture ballast label matches before ordering.

Compatible Applications

Fixtures wired for a M47 ANSI-type metal halide ballast circuit
E39 Mogul Screw socket fixtures rated for 1000W metal halide lamps
High-bay industrial and warehouse lighting
Parking structure and large-area exterior lighting
Burning position: VBU (Vertical, Base Up)

Before Ordering – Verify

Confirm your fixture's ballast is rated ANSI type M47 — GE metal halide ballasts are not interchangeable across different ANSI type codes, and pulse-start ignition systems are not interchangeable with probe-start ballast circuits; verify the ballast label before ordering.
Confirm base type (E39) and burning position (VBU — Vertical, Base Up) match your fixture — operating a lamp outside its rated position can shorten lamp life.
GE lists a restricted/special fixture designation (“S”) for this lamp — verify fixture enclosure and orientation requirements with GE documentation before ordering.
Confirm order code 44835 (GE MVR1000/VBU/HO) exactly matches the lamp or ballast label on your existing fixture before purchasing a replacement.
Case pack quantity is 6; confirm this meets your order needs.

Safety and Handling Guidelines

Contains mercury — dispose of in accordance with local, state, and federal regulations; do not place in regular household trash. Use a certified lamp recycler where required.
Always de-energize the fixture and allow the lamp to cool completely before relamping or servicing.
Metal halide lamps carry a small risk of non-passive (violent) failure at end of life or if operated past rated life; use only in a fixture with the enclosure/containment specified by the fixture manufacturer.
After a power interruption, allow the lamp to cool before it will restrike and return to full output — this is normal metal halide behavior, not a defect.

Compliance

Contains mercury; recycle/dispose of per applicable RoHS, EPA, and state lamp-disposal regulations.
Manufactured to GE's published ANSI lamp/ballast standard for the listed ballast type.
