Philips CDM-TD 70W Double-Ended HID Bulb

This Philips MasterColor CDM-TD is a 70-watt high-intensity discharge lamp with an RX7s double-ended base. It produces a cool white 4200K colour impression and delivers 6500 lumens with a colour rendering index above 90. The lamp is designed for horizontal burning positions within a 45-degree tilt.

Suited for retail display

The compact arc allows high beam intensities in compatible luminaires, and the stable colour output lasts for a rated 16000 hours. Buyers who need a single-ended base, a different colour temperature or instant restrike capability should consider other lamp types. This unit requires a matching ballast and ignitor to operate.

Verify your fixture and control gear before ordering

Confirm the luminaire accepts an RX7s double-ended lamp and is rated for 70W CDM-TD operation with ANSI code M139/E. Ensure the installed ballast and ignitor are compatible with this specification and that the mounting orientation stays within the horizontal +/-45 degree limit.
