GE 23729 MVR350VBUXHOPA/E — 350W Pulsearc Pulse-Start Metal Halide Lamp

The GE MVR350VBUXHOPA/E (order code 23729) is a 350-watt Pulsearc® Multi-Vapor® pulse-start metal halide lamp with a ED37 bulb and E39 Mogul Screw base, designed as a direct replacement lamp for HID fixtures built around a M131 ANSI ballast circuit.

Technical Specifications

Product Overview

The GE MVR350VBUXHOPA/E is a 350-watt Pulsearc® Multi-Vapor® pulse-start metal halide lamp finished in clear glass, rated at 65 CRI and 4000K color temperature. It ships with a ED37 bulb envelope on a E39 Mogul Screw base and is built to operate on a M131 ANSI-type metal halide ballast.

GE's Pulsearc® line uses pulse-start (igniter-based) arc tube technology, which typically delivers faster warm-up and re-strike, more consistent color over life, and higher efficacy than older probe-start designs of similar wattage. These lamps are commonly used as upgrades or replacements in enclosed HID fixtures such as wall packs, high-bay fixtures, and area/flood lights.

At 20,000 hours rated life and 36,500 initial lumens, this lamp is intended as a like-for-like replacement for GE order code 23729 — confirm the code printed on your existing lamp or fixture ballast label matches before ordering.

Compatible Applications

• Fixtures wired for a M131 ANSI-type metal halide ballast circuit
• E39 Mogul Screw socket fixtures rated for 350W metal halide lamps
• General commercial and industrial area lighting
• Parking lot, warehouse, and wall pack fixtures already equipped with a matching ballast
• Burning position: VBU (Vertical, Base Up)

Before Ordering – Verify

• Confirm your fixture's ballast is rated ANSI type M131 — 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.
• This lamp requires an enclosed fixture with a UV-absorbing outer lens or globe; it is not rated for open-fixture use.
• Confirm order code 23729 (GE MVR350VBUXHOPA/E) 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.
• Do not operate this lamp in an open fixture — open-fixture operation of an enclosed-fixture-rated lamp can expose users to UV radiation and increases the risk of injury if the lamp fails.

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.
