Philips 232595 CDM330/U/O/4K EA

The Philips 232595 CDM330/U/O/4K EA MasterColor AllStart Lamp is a premium 330-watt ceramic metal halide (CMH) bulb engineered as a high-efficiency energy retrofit for commercial and industrial lighting systems. Delivering a crisp 4000K cool white light, this universal-burn lamp features an integrated protective shield and an EX39 extended mogul screw base, making it fully rated for both open and enclosed fixtures. Designed with AllStart technology, it operates as a direct energy-saving upgrade on standard 400W pulse-start magnetic ballasts or dedicated electronic ANSI C182 / M155 control gear.

ADL Supply Expert Application & Replacement Guide

The Philips MasterColor CDM330/U/O/4K EA is primarily utilized by maintenance crews servicing large-scale commercial high-bays, warehouse spaces, manufacturing facilities, and outdoor parking lot floodlights. The "AllStart" internal chemistry allows facility managers to drop these 330W modules directly into existing 400W pulse-start magnetic fixtures, immediately trimming energy consumption by up to 15% without necessitating full, costly ballast replacements or complete LED luminaire modifications.

Because this module features a built-in protective glass shroud surrounding the inner ceramic arc tube, it carries an open-fixture rating (denoted by the "/O" in the part code) and is equipped with an **EX39 extended mogul tip**. This prevents it from being incorrectly threaded into standard E39 sockets. When relamping, electrical contractors must ensure the system gear is a thermally protected magnetic or electronic ballast to prevent high-voltage cycling issues or premature startup failure in field components.

Operation, Safety & Mounting Compliance

Warm-Up, Restrike & Ignition Mechanics

Following a cold startup, this high-intensity discharge lamp requires an initialization period of approximately 2 to 4 minutes to achieve uniform arc stability and full lumen output calibration. In the event of a brief power interruption or sudden voltage drop, a hot restrike cooldown window of 5 to 10 minutes is strictly required before the system ignitor can successfully fire the arc path again.

Thermal and Control Gear Requirements

This metal halide module operates strictly on thermally protected control gear frameworks. Running this lamp on unshielded or incorrect legacy probe-start ballasts not specified for AllStart performance will cause rapid thermal accumulation, leading to accelerated shroud failure and severe degradation of service life.

Mercury Content and Disposal Regulations

This high-wattage lamp contains trace amounts of mercury and must be managed under proper environmental disposal frameworks. Commercial maintenance operations should utilize localized bulk lamp recycling channels rather than general commercial waste facilities when executing complete area retrofits.
