Philips MasterColour CDM-R111 lamp

This 70 watt ceramic metal halide lamp produces 2850 lumens at a cool white 4200 Kelvin colour temperature. It is built for retail displays, galleries and hospitality spaces that need crisp white light with excellent colour quality over a long 11000 hour service life.

GX8.5 twist and lock base with 40 degree flood

The GX8.5 cap uses a twist and lock system for quick installation in compatible 111 mm reflector fixtures. A 40 degree flood beam covers wider display areas while the integrated protection glass allows use in open luminaires without extra shielding.

Sustained output with reduced glare over 11000 hours

Ceramic metal halide technology maintains stable colour and lumen output throughout the rated life rather than fading quickly. The improved cap design cuts glare during continuous operation, making it suitable for all day lighting in shops and showrooms.

Questions about this item

How does the 70 watt HID lamp behave when run continuously for many hours?

The ceramic metal halide design maintains stable 2850 lm output and 4200 K colour throughout its 11000 hour rated life, so sustained operation does not degrade light quality.

What thermal and acoustic output should I expect from the 70 watt CDM-R111 during all‑day use?

The integrated protection glass and 111 mm reflector direct heat forward; the lamp runs silently with no fan, so only the fixture surface becomes warm.

Which ballast and fixture does the GX8.5 base require to operate?

A compatible 70 watt ceramic metal halide ballast (ANSI M139/O) and a GX8.5 twist‑lock socket in an open‑rated luminaire are needed for the lamp to strike and run.
