OSRAM SIRIUS HRI 230W (7R lamp) - Discharge lamp with integrated reflector for moving heads and "beam" effects
The OSRAM SIRIUS HRI 230W —commonly known as the 7R lamp —is a metal halide discharge lamp with an integrated reflector , specifically designed for moving heads, scanners, and entertainment effects . Its ultra-short arc of 1 mm and high internal pressure generate extremely high luminance and a very sharp beam , ideal for long-range projections. It delivers a luminous flux of 9,500 lm with a color temperature of 8,000 K and a CRI Ra 75 , maintaining stable output throughout its lifespan . It operates at 230 W with 70 V and 3.3 A , requires forced cooling , and supports a universal burn-in position for easy integration into multiple fixtures.

Frequently Asked Questions
Is the working orientation “universal”? Yes. The burner design allows for a universal (Any) burning position .
Does it need active ventilation? Yes. Forced cooling is mandatory to maintain performance and lifespan.
What ignition voltage does it require? It needs an ignition voltage of 2.5 kVp supplied by the projector's control equipment.
What is its lifespan? The nominal lifespan is 2,500 hours under correct operating conditions.
Safety and handling
- Due to its high luminance , UV radiation and high internal pressure , always operate in closed housings with adequate UV filtering.
- Contains mercury: In case of breakage, follow safety procedures and hazardous waste management procedures.
