GE 20931 MVR400SP30VBU/HO — 400W High Output Multi-Vapor Metal Halide Lamp

The GE MVR400SP30VBU/HO (order code 20931) is a 400-watt High Output / Extra High Output Multi-Vapor® metal halide lamp with a ED37 bulb and E39 Mogul Screw base, designed as a direct replacement lamp for HID fixtures built around a M59 ANSI ballast circuit.

Technical Specifications

Product Overview

The GE MVR400SP30VBU/HO is a 400-watt High Output / Extra High Output Multi-Vapor® metal halide lamp finished in clear glass, rated at 70 CRI and 3200K color temperature. It ships with a ED37 bulb envelope on a E39 Mogul Screw base and is built to operate on a M59 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 20,000 hours rated life and 34,000 initial lumens, this lamp is intended as a like-for-like replacement for GE order code 20931 — confirm the code printed on your existing lamp or fixture ballast label matches before ordering.

Compatible Applications

• Fixtures wired for a M59 ANSI-type metal halide ballast circuit
• E39 Mogul Screw socket fixtures rated for 400W 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 M59 — 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 20931 (GE MVR400SP30VBU/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.
