GE 29488 CMH20PAR30/SP15

The GE ConstantColor 29488 CMH20PAR30/SP15 Spotlight is a premium, high-efficacy 20-watt ceramic metal halide (CMH) long-neck reflector lamp engineered for precision commercial and retail accent lighting tracks. Delivering 1,200 initial lumens of crisp 3000K warm white light, this high-intensity spotlight projects a tightly controlled 15° narrow spot beam spread yielding an impressive 14,500 center beam candlepower (CBCP). Built with an industry-standard E26 medium screw base and an integrated UV-blocking glass shell, it provides an extended 12,000-hour rated average service life.

ADL Supply Expert Application & Replacement Guide

The GE ConstantColor 20W PAR30L narrow spot lamp is a premium retail lighting standard specified for high-end boutique display windows, art galleries, automotive showrooms, luxury hotel lobbies, and dramatic architectural coves. Engineered with an advanced ceramic arc container housed inside a rigid glass reflector envelope, this lamp restricts the muddy green color shifts common in standard quartz metal halide bulbs—delivering a crisp, stable 60 lumens-per-watt footprint that makes merchandise or structural accents pop under long-distance throws.

Ballast and Enclosure System Guidelines for Electricians: This module carries an official ANSI Open-Fixture Rating (C156/O). Because the outer long-neck glass lens serves as an integrated secondary explosion containment shield, it is fully approved for use in both open track heads and enclosed downlight trims. Maintenance personnel must ensure that fixtures run a compatible low-frequency electronic ballast rated precisely for **ANSI C156 circuits**. Operating this capsule on legacy magnetic or mismatched HID ballasts will cause acute current fluctuations, accelerated end-of-tube blackening, and premature lamp failure. Its integrated universal burning orientation allows trouble-free mounting at any directional angle.

Operation, Safety & Mounting Compliance

Warm-Up, Cooldown, and Hot Restrike Intermissions

Following a cold strike initialization, this high-intensity discharge spot lamp requires an initialization window of 3 to 5 minutes to fully vaporize internal gas elements and achieve steady spectral color rendering. In the event of an unexpected circuit interrupt or localized power sag, a hot restrike safety delay of 7 to 12 minutes must be allowed. This lets internal operating arc pressures balance completely before the pulse-start electronic ignitor can safely re-fire the lamp capsule.

FadeBlock™ UV Protection and Handling Care

This single-ended source incorporates integrated UV-reduction barrier technology built into the outer glass shell, significantly filtering out shortwave ultraviolet radiation. This feature drastically curbs fabric fading, yellowing, or textile deterioration common down high-end showroom apparel racks and art gallery panels. Never install this bulb if the outer front glass lens becomes cracked, deeply chipped, or broken. Always isolate line inputs and permit a 15-minute cooling phase before servicing track heads to protect against burns.
