Philips 245159 MSD 250-2 30H

The Philips Broadway MSD 250/2 30H (245159) Lamp is a commercial-grade, high-intensity short-arc entertainment discharge bulb engineered exclusively for professional moving-head automated spots, theatrical color scanners, followspots, studio profile projectors, and high-intensity architectural display fixtures. Delivering a brilliant 18,000 initial lumens of crisp 8500K ice-daylight illumination, this premium single-ended module utilizes an advanced high-pressure gas fill to achieve an efficient 72 lm/W efficacy across a 70 CRI color accuracy baseline. Outfitted with precision GY9.5 bi-pin prefocus bases and a compact 108mm chassis footprint, it provides an extended 3,000-hour rated average service life with universal burning position flexibility across any spatial orientation.

ADL Supply Expert Application & Replacement Guide

The Philips Broadway MSD 250/2 30H short-arc discharge lamp is an established concert entertainment baseline specified heavily by theatrical fixture crews, live event production teams, and architectural system integrators for automated moving head spots, color scanners, followspots, and high-intensity presentation projectors. Featuring an intensely focused 5mm compact arc gap, it projects a concentrated, blue-rich 8500K daylight beam that cuts through heavy synthetic stage fog and complex laser fields with absolute definition, maximizing beam output contrast throughout its operational lifecycle.

Critical High-Voltage Igniter Requirements and Dedicated MSD Ballast Circuit Boundaries: Stage technicians and lighting crew chiefs executing routine fixture repairs must analyze equipment ballast data parameters closely prior to checkout: this specialized MSD short-arc capsule functions strictly when driven by a dedicated electronic or magnetic control ballast rated specifically for MSD/MSR 250W discharge platforms. While the bulb settles into a 90V AC running voltage once ionized, striking the cold gas column requires an intense 2.5 kV to 4.5 kV (2,500V to 4,500V) high-voltage ignition pulse from an approved external igniter.

Attempting to run this medium source discharge bulb on standard domestic commercial metal halide ballasts (such as CWA core-and-coil, pulse-start, or probe-start reactor networks) will fail to generate the necessary starting spark or current regulation, leading to immediate non-ignition or terminal component failure. Furthermore, following any abrupt power dropouts, a complete hot restrike cool-down interval must be strictly observed. Attempting to re-strike the arc before internal quartz envelope pressures normalize will cause non-ignition or accelerate cathode degradation.

Operation, Safety & Mounting Compliance

Low-Frequency Square-Wave Electronic Balance Control

When driven by modern high-efficiency electronic entertainment ballasts, this lamp processes power over precise low-frequency square waves, completely preventing internal acoustic arc resonance and visual plasma shifting loops typical under old magnetic line signals. This advanced electronic stabilization maintains color-point integrity across your entire moving-head tracking wash row, ensuring adjacent spotlights project matched visual depth without color drift.

Mercury Content Dosing and Safe Bulk Recycling Protocols

This short-arc high-intensity capsule utilizes a highly concentrated chemical vapor volume of heavy-metal mercury to activate its hyper-bright discharge illumination track. While structurally shielded to endure extreme physical moving acceleration and intense internal atmospheres, it remains a hazardous component at end-of-life cycles. National environmental safety laws mandate processing spent modules through certified commercial e-waste repository centers during staging teardown sweeps rather than discharging them into municipal solid landfills or common trash streams.
