Product Overview

The Philips 23365-0 MasterColor CDM-PAR20 is a high-efficacy ceramic metal halide spot lamp engineered for retail accent, decorative, and downlighting applications requiring tight beam control and excellent color quality in a compact PAR20 footprint. The 10° spot beam spread concentrates light precisely on merchandise and display subjects, while CRI 81 and 3000K warm white deliver accurate, pleasant color rendering for retail environments.

FadeBlock technology integrates a UV-blocking medium into the hard glass reflector, reducing fading damage to fabrics, artwork, and merchandise from UV exposure — an important consideration for retail and gallery applications with long display durations. Lifetime color stability within ±200K and lamp-to-lamp consistency ensure uniform appearance across multiple fixtures in the same space, which is critical for retail displays using multiple lamps. This lamp's compact size makes it suitable for both open and enclosed fixture designs, and it is rated for outdoor luminaire use as well.

Important: This lamp operates only on thermally protected CMH ballasts matched to ANSI C130/O. Confirm ballast compatibility before ordering — using an incompatible or non-thermally-protected ballast can create a safety hazard.

Compatible Applications

Retail accent and decorative lighting — 10° spot beam for precise merchandise highlighting in jewelry, apparel, and specialty retail.
General lighting and downlighting — Compact PAR20 form factor for recessed and track fixtures in retail and commercial spaces.
UV-sensitive display environments — FadeBlock UV-blocking technology protects fabrics, artwork, and merchandise from UV-related fading.
