OSRAM SIRIUS HRI 330 W – Discharge lamp with reflector for moving heads (7400 K, 18,000 lm, 1,500 h)

OSRAM SIRIUS HRI 330 W – Discharge lamp with reflector for moving heads (7400 K, 18,000 lm, 1,500 h)

The OSRAM SIRIUS HRI 330 W is a short-arc discharge lamp with an integrated reflector , specifically designed for compact moving heads (beam/spot/wash) and professional lighting effects. Its very high luminance comes from an arc of just 1.0 mm and high internal pressure , producing powerful and well-defined beams. It delivers a nominal luminous flux of 18,000 lm , a color temperature of 7,400 K (cool "daylight" white), and a CRI Ra 86 , maintaining stable light output throughout its lifespan. The burner design allows for "Any" operating position , and the reflector module makes replacement quick and easy , streamlining maintenance on tour or during installation.

For reliable integration, the lamp operates at 330 W with 65 V and 5 A , and requires 2.5 kVp ignition via electronic control equipment ( ECG ) and forced cooling . Its maximum aperture window of 8.0 mm and working distance of 31 mm facilitate optical alignment in compatible projectors. With a diameter of 56 mm , a length of 63 mm , and a weight of approximately 75 g , it is ideal for small, lightweight moving heads that require bright light for effects and a rated life of 1,500 hours .

Main features

• High luminance thanks to the very short arc (≈1.0 mm) and the high internal pressure.
• Integrated reflector in a compact module for quick replacement and repeatable alignment.
• Stable color at 7,400 K with CRI Ra 86 ; uniform output throughout its lifespan.
• “Any” burn position and forced cooling to ensure performance and durability.
• Nominal life 1,500 h , ideal for rental , events and intensive use.

Product benefits

• Powerful and defined beams for aerial effects, gobos and cutouts with high visual impact.
• Fewer maintenance stops thanks to the reflector design and quick lamp change.
• Wide compatibility with 330W projectors using SIRIUS HRI modules.
• Consistent color and level throughout the lifecycle, simplifying adjustments in show.

Use cases

• Concerts and festivals : highly concentrated beams and long-distance effects.
• Theatre and musicals : bright accents and textures with gobos.
• Clubs and corporate events : dynamic looks in compact moving heads.
• TV/studio and architainment : high-punch cool whites for cameras and large spaces.

Frequently Asked Questions

• Is it dimmable? The lamp is compatible with suitable electronic control; always respect the specifications of the luminaire manufacturer and the ECG.
• What equipment is needed? It requires 2.5 kVp startup , 65 V / 5 A operation, and forced cooling in a system designed for SIRIUS HRI 330 W.
• Can it be mounted in any orientation? Yes, "Any" working position .
• Are there any safety precautions? Due to its high luminance, internal pressure, and UV radiation, operate only in enclosed housings with suitable filters and follow the manufacturer's safety instructions.

Installation and safety

• Disconnect the equipment and allow it to cool before handling; wear clean gloves and eye protection.
• Check the mechanical compatibility of the module with the reflector and the working distance (31 mm) .
• Respect nominal electrical values ​​(330 W, 65 V, 5 A) and 2.5 kVp ignition ; ensure adequate ventilation .
• Manage the lamp at the end of its life in accordance with WEEE/local regulations.
