OSRAM SIRIUS HRI 440 WX – Short arc discharge lamp for moving lights and high intensity effects

The OSRAM SIRIUS HRI 440 WX is a high-pressure mercury vapor lamp with an ultra-short arc (≈1 mm) and reflector integration , designed for moving heads and entertainment projectors requiring extremely high luminance , a flux of 22,800 lm , and a color temperature of 7,000 K. With a nominal voltage of 83 V and 5.3 A ( ≈440 W ), it offers a CRI of 80 and a lifespan of 1,500 hours , maintaining stable output throughout its lifecycle. Its burner design allows for burning in any orientation and a working distance of 41 mm for precise optical coupling in compact luminaires. It is an industry standard and equips, among others, the Clay Paky Mythos 2 .

Main features

• Ultrashort high luminance arc (≈ 1 mm ) for highly concentrated beams and defined effects.
• Power 440 W with 83 V and 5.3 A ; CRI 80 , CCT 7,000 K and 22,800 lm nominal flux.
• Integrated reflector optimized for lightweight and compact moving heads .
• Stable output and low lumen depreciation over the life of the lamp.
• Burning position: Any (any orientation) for greater design flexibility.
• Compact dimensions : Ø 58 mm and length 71 mm ; weight approx. 135.5 g .

Product benefits

• Bright light for beam/spot effects with sharp edges and high intensity.
• Easy integration into entertainment luminaires thanks to the reflector and working distance of 41 mm .
• Longer service life with a nominal 1,500 hours and stable performance.
• Effectiveness in real-world scenarios : cool color (7,000 K) that cuts through fog and smoky environments.

Use cases

• Live shows : concerts, festivals, theatre, tours.
• Clubs and events with high-performance moving heads.
• Television and studios that demand intense and consistent beams.
• Architectural and effects applications ( architainment ).

Compatibility and examples

Compatible with many 440W moving head fixtures on the market; for example, the Clay Paky Mythos 2 is supplied with an OSRAM SIRIUS HRI 440W X lamp, replacing previous models in the same family. Exact compatibility depends on the lamp holder and the luminaire manufacturer's design.

Frequently Asked Questions

• What is the arc length? Approximately 1.0 mm , responsible for the high luminance and the concentrated beam.
• What does “Any” mean in the burn position? The burner design allows operation in any orientation , facilitating its use in different light fixtures.
• What is the typical lifespan? Around 1,500 hours under nominal conditions and with proper cooling.
• Thermal requirements? Forced cooling according to the luminaire specification to maintain arc stability and service life.

Safety and handling

• Always handle with the equipment disconnected and after the lamp has completely cooled down .
• Avoid touching the reflector bulb/window with your fingers; wear clean gloves .
• Contains mercury; manage end of life in accordance with applicable regulations.
• Use only in luminaires designed for SIRIUS HRI and with compatible ballast/ignitor .
