PHILIPS 429886 MHC100/U/M/4K ELITE 100W 4000K ED17

The Philips 42988-6 MasterColor Elite MHC100/U/M/4K/ELITE Lamp is a premier 100-watt ceramic metal halide (CMH) bulb engineered for high-performance retail display and upscale commercial environments. Delivering a powerful 9,500 initial lumens of a crisp 4000K deluxe cool white spectrum, this high-efficacy lamp features an Elite-level 92 CRI rating for unmatched color rendering and fidelity. Built with an E26 medium screw base and a clear, compact ED17 glass envelope, it offers a reliable 16,000-hour rated average service life across an adaptable universal burning orientation.

ADL Supply Expert Application & Replacement Guide

The Philips MasterColor Elite MHC100 is an industry-recognized specification for architectural downlighting, high-end commercial showrooms, luxury car boutique galleries, and modern retail environments. By leveraging an advanced ceramic discharge arc tube design, this lamp sustains excellent lumen maintenance and minimizes color drifting across its lifetime compared to legacy quartz metal halide bulbs. Its integrated FadeBlock UV protection filter shield effectively curbs harmful ultraviolet output, significantly reducing the fading or fabric deterioration common in high-end apparel displays and museum art installations.

Safety & Fixture Compliance Note: This clear CMH module carries a strict ANSI Enclosed-Fixture Rating (denoted by the "/E" suffix). Because it is unshielded, national electrical codes mandate its use exclusively within fully enclosed luminaires fitted with tempered, thermal-shock-resistant glass lenses. Electrical contractors must ensure control systems incorporate an **M140 or M90 pulse-start ballast architecture**. Pairing this lamp with older probe-start or mismatched HID ballasts will cause severe operating current irregularities, leading to premature arc tube failure or sudden jacket clouding in the field.

Operation, Safety & Mounting Compliance

Warm-Up, Cooldown, and Restrike Delays

Following a cold strike initiation, this high-intensity discharge lamp requires an initialization window of approximately 3 to 5 minutes to fully vaporize internal metal halide salts and achieve steady spectral color rendering. In the event of an unexpected localized current sag or power interruption, a hot restrike safety delay of 10 to 15 minutes must be allowed to let internal operating arc pressures balance completely before the system ignitor can safely reignite the lamp.

Ultraviolet Radiation Handling Safeguards

This industrial optical source generates shortwave ultraviolet (UV) radiation during active operation. Never operate this lamp if the outer ED17 clear glass envelope becomes scratched, cracked, or broken. Running a fractured bulb introduces severe safety hazards, including serious skin tissue burns and acute eye inflammation from unfiltered UV emissions. Always isolate line power and permit a 15-minute cool-down phase before executing re-lamping procedures. Ensure no bare skin contacts the clear bulb face; handle using a clean cloth to prevent natural skin oils from creating localized thermal hot spots that trigger early envelope failure.
