Compact Ceramic Metal Halide Lamp

The Philips MasterColor CDM-TM 20W/830 is a 20 watt ceramic metal halide bulb with a PGJ5 base. It delivers 1650 lumens at a warm 3000K colour temperature for accent and display lighting in retail, general indoor and outdoor areas. The compact single-ended design fits small luminaires where space is limited. Buyers needing higher lumen packages or different base types should look elsewhere.

Stable Output Over Rated Life

Rated life reaches 12000 hours with stable colour performance and lumen maintenance throughout that period. The lamp maintains its 3000K warm white appearance and CRI of 82 from installation to end of life. High efficacy ensures consistent crisp white sparkling light without the colour shift common in some discharge technologies. It is not suited for applications requiring instant restrike or frequent rapid cycling.

Miniature PGJ5 Base for Discreet Fixtures

The PGJ5 base and mini dimensions allow integration into compact luminaires that stay visually unobtrusive in display settings. Excellent colour rendering at CRI 82 makes merchandise appear vibrant and true. The single-ended construction simplifies relamping in tight fixtures. Installations requiring screw bases, larger form factors or integrated control gear cannot use this lamp.

Questions about this item

How much heat and power does the 20W ceramic metal halide lamp generate during continuous all-day operation?

The lamp draws 20 watts and produces a warm 3000K beam at 1650 lumens; ceramic metal halide technology runs cooler than traditional halide sources but still requires a ventilated fixture rated for HID use.

What ballast and fixture must I already own for the PGJ5 base to work?

A compatible electronic or magnetic ballast rated for 20W CDM-TM lamps and a PGJ5 socket in an enclosed, ventilated luminaire are required before installation.

Will the 3000K 82 CRI output match the colour of my existing halogen accent lights?

The 3000K warm white with 82 CRI renders colours similarly to halogen, though the spectrum is crisper; side-by-side differences are minimal in retail display settings.
