OSRAM HSR 400W Metal Halide Lamp

The OSRAM HSR 400W metal halide lamp is a high intensity discharge bulb designed for professional stage, architectural and event lighting. It produces a crisp 5900K daylight colour temperature with a colour rendering index of 85. The lamp delivers 33000 lumens for demanding entertainment fixtures and automated luminaires.

Replaces Worn HSR Lamps in Fixtures

This bulb serves as a direct replacement for expired HSR short arc lamps in compatible moving heads, follow spots and architectural units. The jump is worth it when an existing lamp has reached its 650 hour rated life and output or colour stability has degraded. Fresh lamps restore the original balance of lumen output and daylight colour quality.

Verify Fixture Compatibility and Voltage

Confirm the fixture accepts a 400W HSR metal halide lamp with the correct base and arc gap before ordering. Check that the ballast or power supply matches the lamp's electrical requirements. Ensure the luminaire's cooling and ignition system is rated for this specific lamp type and wattage.

Questions about this item

What fixture type accepts the OSRAM HSR 400W metal halide arc lamp?

It fits automated stage fixtures designed for short-arc HSR metal halide lamps with a 400W rating.

How is the OSRAM HSR 400W lamp installed, and what step is often missed?

Insert the lamp into the fixture's dedicated HSR socket, then secure the retaining clip; the step often missed is reseating the clip fully so the arc tube aligns with the optical path.

When will the OSRAM HSR 400W lamp need replacement based on its rated life?

Plan replacement after approximately 650 operating hours, when output drops below the rated 33000 lumens and the 5900K colour temperature shifts.
