Philips 350W Metal Halide Lamp

The Philips 132928 is a 350 watt ceramic metal halide lamp with an EX39 exclusionary mogul screw base. It operates at 150 volts and produces a 4200K colour temperature for commercial and industrial lighting installations. Designed for vertical burning within a fifteen degree tolerance, it suits high-bay and outdoor fixtures requiring pulse-start ignition.

ALTO Pulse-Start Benefits

The ALTO low-mercury construction reduces environmental impact while the pulse-start system enables faster restrike and improved lumen maintenance over probe-start alternatives. A coated ED37 envelope softens glare and the 900 series rating confirms the lamp meets specific performance standards for enclosed fixture operation. Buyers needing horizontal burning positions or non-exclusionary bases should select a different model.

Questions about this item

How often will the 350 watt Metal Halide bulb need replacement?

The MasterColor Pulse Start ceramic metal halide lamp is rated for a long service life; plan on replacing it when light output drops noticeably after many thousands of hours.

What limits continuous operation of the vertical-burn EX39 bulb?

The bulb must stay within ±15 degrees of vertical; tilting beyond that angle shortens life and can cause early failure.
