Philips CDM-TD 70W Double Ended HID Bulb

This Philips MasterColor CDM-TD lamp is a 70 watt high intensity discharge bulb designed for double ended fixtures with an RX7s base. It delivers a warm 3000K colour temperature and 6500 lumen output for retail display lighting, accent applications and commercial spaces needing consistent colour quality. The compact arc design allows precise optical control in compatible luminaires.

Upgrade from Quartz Metal Halide MHN-W-TD

The lamp serves as a direct retrofit for double ended quartz metal halide lamps such as MHN/W-TD types, reducing operating costs through higher efficacy and longer 16000 hour rated life. The jump is worth it when you need stable colour impression over the full lifetime and improved colour rendering with a CRI above 80 compared to older halide sources.

Installation Requires Ballast and Ignitor

CDM-TD lamps must operate with a compatible ballast and ignitor matched to the 70 watt ANSI C139/E specification. The burning position is restricted to horizontal ±45 degrees, so mounting outside this range will cause premature failure. A UV block quartz outer bulb is fitted, but the fixture must still provide appropriate enclosure for safety.

Questions about this item

What RX7s lampholder spacing does the 70 W CDM-TD require?

The double-ended RX7s base fits standard 70 W ceramic metal halide sockets; verify the fixture is rated for 70 W and the ANSI C139/E code before installing.

Which burning position is approved for this horizontal ±45° lamp?

Install the bulb horizontally within 45 degrees of level; operating outside this range shortens the 16 000-hour life and can cause early arc instability.

When should the UV-block quartz envelope be replaced?

Replace the lamp after 16 000 hours or when light output drops noticeably; the UV-block quartz does not degrade separately, so the whole bulb is changed at end of life.
