Product Overview

The GE MXR70/C/U/MED/O is a 70-watt Protected Multi-Vapor® metal halide lamp finished in coated glass, rated at 70 CRI and 3200K color temperature. It ships with a ED17 bulb envelope on a E26 Medium Screw base and is built to operate on a M98 ANSI-type metal halide ballast.

As a Protected Multi-Vapor® lamp, this SKU includes an integral shroud/arc-tube shielding designed by GE for use in open fixtures (fixtures without a separate UV-absorbing outer lens), unlike standard Multi-Vapor lamps which require an enclosed fixture. Always confirm your specific fixture's open-fixture rating against GE's current documentation before relying on this feature.

At 15,000 hours rated life and 4,900 initial lumens, this lamp is intended as a like-for-like replacement for GE order code 12577 — confirm the code printed on your existing lamp or fixture ballast label matches before ordering.

Compatible Applications

Fixtures wired for a M98 ANSI-type metal halide ballast circuit
E26 Medium Screw socket fixtures rated for 70W metal halide lamps
Open (non-enclosed) commercial and industrial fixtures designed for Protected/self-shielded lamps
Wall packs, floodlights, and area fixtures where an enclosed-fixture lamp is not specified
Burning position: U (Universal (any burning position))

Before Ordering – Verify

Confirm your fixture's ballast is rated ANSI type M98 — 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 (E26) and burning position (U — Universal (any burning position)) match your fixture — operating a lamp outside its rated position can shorten lamp life.
This lamp is Protected/open-fixture rated per GE, but confirm your specific fixture's listing and local code requirements before installing it in an open (non-enclosed) fixture.
Confirm order code 12577 (GE MXR70/C/U/MED/O) 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.
