Product Overview
The GE MXR100/C/U/MED is a 100-watt Pulsearc® Multi-Vapor® pulse-start metal halide lamp finished in coated glass, rated at 70 CRI and 3200K color temperature. It ships with a BD17 bulb envelope on a E26 Medium Screw base and is built to operate on a M90 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 15,000 hours rated life and 8,500 initial lumens, this lamp is intended as a like-for-like replacement for GE order code 18679 — confirm the code printed on your existing lamp or fixture ballast label matches before ordering.
Compatible Applications
- Fixtures wired for a M90 ANSI-type metal halide ballast circuit
- E26 Medium Screw socket fixtures rated for 100W 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 M90 — 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 requires an enclosed fixture with a UV-absorbing outer lens or globe; it is not rated for open-fixture use.
- Confirm order code 18679 (GE MXR100/C/U/MED) 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.
