GE 85110 CMH20MR16/830/FL

The GE CMH20MR16/830/FL is a professional-grade ConstantColor® Ceramic Metal Halide 20W flood lamp engineered for demanding commercial accent and display applications. Delivering 2,900 CBCP and 1,000 lumens of stable 3000K warm white performance, this system utilizes a GX10 twist-lock ceramic base configuration to optimize color consistency and lifespan parameters across high-end retail, gallery, and architectural fixture frameworks.

ADL Supply Expert Application & Replacement Guide

The GE CMH20MR16/830/FL is primarily specified by lighting designers, electrical contractors, and facility managers across high-end retail showcases, jewelry display cases, museum galleries, and commercial atrium accent systems where warm 3000K color rendering and long relamping intervals are both critical priorities. This lamp requires a dedicated 20W low-frequency electronic ballast conforming to ANSI C156/M156 — compatible GE ballast models include the GE 63042 (GEMH20-MSJ-MV) and GE 63043 (GEMH20-MSF-MV) — and will not ignite on magnetic ballasts, non-ANSI-matched electronic units, or ballasts rated for standard probe-start metal halide lamps. The GX10 twist-lock ceramic base is intentionally incompatible with the two-pin GU10 halogen socket, so contractors retrofitting existing halogen MR16 fixtures must replace the socket assembly before installation; this mis-lamp prevention feature is a deliberate safety and performance design element of the CMH platform.

Operation, Safety & Mounting Compliance

Ballast & Electrical Requirements

This lamp must be operated exclusively on a 20W low-frequency electronic ballast conforming to ANSI C156/M156 specifications. Operation on incompatible ballasts — including magnetic units, high-frequency electronic ballasts, or ballasts rated for standard probe-start MH lamps — will result in non-ignition, erratic color, or premature arc tube failure not covered under warranty. Verify ballast ANSI code compliance before installation. Recommended GE-matched ballasts are the GE 63042 (GEMH20-MSJ-MV) and GE 63043 (GEMH20-MSF-MV). As with all HID lamp types, allow a minimum 15-minute cool-down period before relamping — ceramic metal halide lamps operate at elevated internal pressure and must never be handled or re-struck while hot.

Handling, UV Safety & Environmental Compliance

This lamp contains mercury sealed within the ceramic arc tube and must be disposed of through a certified lamp recycling program in compliance with applicable federal, state, and local regulations — do not discard in standard municipal solid waste. The integrated UV-filtering outer jacket eliminates the need for a secondary UV shield in most open-fixture commercial applications, though installers should confirm the fixture manufacturer's open-face mounting guidelines. Handle by the base only — fingerprint oils on the outer glass jacket can create thermal stress points that accelerate envelope failure. This product carries an open or enclosed fixture rating (ANSI /O designation), providing installation flexibility across a wide range of commercial luminaire types.
