GE 18205 MVR1000/U/BT37

GE 18205 MVR1000/U/BT37 — 1000W Multi-Vapor Metal Halide Lamp

The GE MVR1000/U/BT37 (order code 18205) is a 1000-watt Multi-Vapor® metal halide lamp with a BT37 bulb and E39 Mogul Screw base, designed as a direct replacement lamp for HID fixtures built around a M47 ANSI ballast circuit.

Technical Specifications

Product Overview

The GE MVR1000/U/BT37 is a 1000-watt Multi-Vapor® metal halide lamp finished in clear glass, rated at 65 CRI and 3700K color temperature. It ships with a BT37 bulb envelope on a E39 Mogul Screw base and is built to operate on a M47 ANSI-type metal halide ballast.

This is a standard GE Multi-Vapor® metal halide lamp from the non-Pulsearc family, widely deployed as a maintenance replacement in existing commercial and industrial HID fixtures already wired for a probe-start or standard M-type ANSI ballast. It is a common stock replacement lamp for parking lot, warehouse, and general area lighting fixtures already in the field.

At 9,000H/12,000V hours rated life and 105,000H/115,000V initial lumens, this lamp is intended as a like-for-like replacement for GE order code 18205 — 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
• General commercial and industrial area lighting
• Parking lot, warehouse, and wall pack fixtures already equipped with a matching ballast
• Burning position: U (Universal (any burning position))

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 (U — Universal (any burning position)) 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 18205 (GE MVR1000/U/BT37) 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.
