OSRAM SIRIUS HRI 440 W – Short arc discharge lamp with reflector (7,000 K, 22,800 lm, CRI 80)

OSRAM SIRIUS HRI 440 W – Short arc discharge lamp with reflector (7,000 K, 22,800 lm, CRI 80)

The OSRAM SIRIUS HRI 440 W is a high-pressure, very short arc discharge lamp designed for professional projectors and moving heads . Its optimized burner and compact reflector provide extremely high luminance and a clean beam, with stable output throughout its lifespan . It delivers a cool-white light of 7,000 K and a reference luminous flux of 22,800 lm (depending on the variant), with a CRI of 80 , ideal for beam, spot, and hybrid effects in stages, clubs, theaters, TV studios, and events.

The design accommodates any operating position and is intended for easy replacement . The system architecture requires forced cooling and suitable electronic equipment (driver) from the luminaire manufacturer to ensure performance, color, and lifespan. Its 1.3 mm arc concentrates light energy, achieving powerful effects even in compact luminaires.

Product benefits

• High luminance thanks to the 1.3 mm arc and high internal pressure: intense and defined beams.
• Uniform and stable light output throughout its lifespan, with consistent color for shows and broadcast.
• Lightweight and compact reflector lamp , suitable for mobile equipment and small format heads.
• Quick installation and maintenance : easy lamp replacement and online authenticity verification (Trust SIRIUS).

Use cases

• Show lighting : beam/spot/wash, hybrids and high-intensity aerial effects.
• Theatre and TV/Studio : projection of defined beams and stable color.
• Clubs, tours and events : compact luminaires with great punch and coverage.

Common compatibilities (examples)

The HRI 440 W is used as a light source in various professional luminaires. For reference, some manufacturers specify this lamp (or a variant thereof) in fixtures such as the Chauvet Maverick MK1 Hybrid and PR Lighting XR 440 , among others. Always verify the exact variant and driver required in your luminaire's manual.

Frequently Asked Questions

What is the difference between variants (e.g., 440 W, 440 WS, 440 WX, 440 WH)?
There are sub-versions with slight differences in luminaire flux, reflector dimensions, working distance, and rated life. The correct choice depends on the luminaire model and its driver; always follow the reference provided by the equipment manufacturer.

Is the lifespan always 1,500 hours?
The nominal lifespan depends on the variant and the thermal/electrical conditions of each luminaire. For the 440 W “Core” and 440 WS, OSRAM publishes up to 1,500 hours in recent commercial documentation; other data sheets for certain sub-versions may indicate 1,000 hours . Schedule your maintenance according to the luminaire manufacturer's guidelines.

How do I verify that the lamp is a genuine OSRAM?
Each SIRIUS HRI incorporates an 11-digit code on the reflector. You can verify its authenticity using the official OSRAM Trust SIRIUS tool.

Installation and safety notes

• Use driver/ECG and cooling profile specified by the luminaire manufacturer.
• Do not touch the bulb/window; clean with a lint-free cloth if necessary.
• Respect recommended power on/off cycles and cooling times.
• After the change, perform focus and alignment according to the team's procedure.
