Philips 70 W CDM-TC Metal Halide

This Philips MasterColor CDM-TC is a 70 watt ceramic metal halide lamp with a G8.5 two-pin base. It delivers 6400 lumens at a 3000 K warm white colour temperature and has a rated life of 12000 hours. The clear tubular T4 quartz envelope uses FadeBlock material to maintain consistent output over its lifetime.

Suited for commercial accent lighting

Fixtures that accept a G8.5 base and run a 70 W metal halide ballast can use this lamp for retail display, hospitality or landscape accent work. Buyers needing a different base type, a higher or lower wattage, or a non-metal-halide technology should look elsewhere.

G8.5 base and 70 watt rating

The G8.5 two-pin base and 70 watt power rating are the two specifications that determine whether this lamp fits the fixture and ballast. Verify both values against the luminaire documentation before purchasing.

Questions about this item

What G8.5 2-pin base does the Philips CDM70/TC/830 use?

The bulb has a G8.5 2-pin base that fits matching ceramic metal halide sockets.

What fixture clearance does the T4 single-ended quartz envelope need?

The compact T4 quartz envelope requires a fixture rated for 70 W ceramic metal halide lamps with adequate ventilation.

How is the MasterColor CDM-TC lamp installed, and what step is often missed?

Insert the G8.5 pins firmly until seated; the common error is not aligning the keyway, which prevents proper electrical contact.
