OSRAM SIRIUS HRI 440 W - Short arc discharge lamp with reflector for moving heads and hybrid spotlights

The OSRAM SIRIUS HRI 440 W is a very short arc discharge lamp with an integrated reflector, designed for demanding moving heads and hybrid (spot/beam/wash) luminaires. Its high-pressure burner and 1.3 mm arc provide high luminance and a highly concentrated beam , with a nominal luminous flux of 22,000 lm , a color temperature of 7,000 K , and a CRI of 80. It has an average lifespan of 1,500 hours , maintaining stable output throughout its service life. It operates with an electronic ballast (ECG) at 83 V and 5.3 A , with a firing voltage of 2.5 kVp . The burner design allows for firing in any orientation and requires forced cooling in enclosed luminaires.

Main features

• Powerful and defined light : 1.3 mm arc, 22,000 lm , 7,000 K , CRI 80 .
• Compact construction : diameter 58 mm , length 71 mm , weight approx. 100 g .
• Electrical : 440 W , 83 V , 5.3 A , ignition 2.5 kVp , working distance 41 mm .
• Operation : nominal life 1,500 h , burning position: any , forced cooling .
• Designed for brilliant effects : high luminance thanks to the very short arc and high internal pressure.
• Easy maintenance : easy lamp replacement; uniform light output throughout its lifespan.

Product benefits

• Visual impact in beam and gobos due to its very high luminance.
• Consistent color (≈7,000 K) and arc stability for extended shows.
• Safe integration with ECG and operation in any position , ideal for modern moving heads.
• Fewer stops : average life of 1,500 h with sustained output.

Use cases

• Shows and tours : concerts, festivals, clubs and corporate events.
• Theatre and television : hybrid spot/beam/wash luminaires with high intensity.
• Architecture and architainment : precise beams and long-range effects.

Common compatibilities (examples)

Manufacturers that use SIRIUS HRI 440 W lamps in different models (always check your light fixture's data sheet):

• Claypaky : Mythos 2, SuperSharpy 2.
• LPG : GT-1.
• Martin : MAC Axiom Hybrid.
• PR Lighting : XR 440 BWS / XR 440 Beam.

Frequently Asked Questions

• Can I use it in any position? Yes, the optimized burner supports any position ; always respect the ventilation and enclosure of the light fixture.
• What is its lifespan? 1,500 nominal hours under correct operating and cooling conditions.
• Does it require an enclosed luminaire? Yes. Due to its high luminance, UV, and internal pressure, it must only operate in enclosed housings with suitable filters.
• Is it dimmable? The dimming and switching depend on the electronic ballast specified by the light fixture manufacturer.

Usage and safety recommendations

• Use ballast/ECG and firmware approved by the equipment manufacturer.
• Ensure forced cooling according to the luminaire manual.
• Do not touch the bulb/reflector; install with gloves and safety glasses.
• Respect the working distance (41 mm) and other mechanical parameters indicated by the luminaire.
