Professional Daylight Lighting

The OSRAM HMI 575w /DXS SFc10-4 is a metal halide lamp built for professional stage, film and large-screen projection work. Its 6000K output matches natural daylight and the CRI of 90 renders colour accurately. The 49000 lumen output suits high-demand exterior and interior lighting. Excellent hot-restart capability reduces downtime during production.

Fixture and Power Compatibility

Verify that the fixture accepts an SFc10-4 base and is rated for a 575 watt metal halide lamp. The ballast must match the lamp wattage and type for safe operation. Ensure the housing and ventilation can handle the heat produced by a high-intensity discharge arc. Confirm the application requires a 6000K daylight source rather than a warmer colour temperature.

Integration and Workflow

The lamp installs directly into compatible follow-spot, fresnel or projector heads using the SFc10-4 base. It frees the lighting designer from colour-gel correction when matching daylight ambient light. The 1000 hour rated life supports extended production schedules before relamping. Hot-restart function allows immediate re-strike after a brief power interruption.

Questions about this item

What comes in the box with the OSRAM HMI 575w /DXS bulb?

The package contains the single metal halide lamp with its SFc10-4 base. No ballast, ignitor or fixture is included; those must be purchased separately to operate the bulb.

How do I choose between the available versions of this 575 watt HMI lamp?

This model is offered in one configuration: 575 watts, 6000K colour temperature, 49000 lumen output and a 1000 hour rated life. Select it when your fixture and ballast are rated for exactly those specifications.

What does the 49000 lumen rating mean when the lamp is installed in a real fixture?

It indicates the total luminous flux the arc produces at 6000K daylight colour. Actual illumination on the stage or set will be lower due to reflector efficiency, lens absorption and distance to the subject.
