OSRAM SIRIUS HRI 471 W SN - Metal halide reflector lamp for moving heads, 20,000 lm and 7,500 K

OSRAM SIRIUS HRI 471 W SN - Metal halide reflector lamp for moving heads, 20,000 lm and 7,500 K

The OSRAM SIRIUS HRI 471 W SN is a lightweight and compact reflector lamp designed for moving heads and entertainment luminaires with electronic control gear (ECG) . Its very short arc at high pressure delivers 20,000 lm with a color temperature of 7,500 K and a CRI of 80 , guaranteeing bright lighting effects and a defined beam . It operates at 471 W with 83 V and 5.3 A , and maintains a stable output throughout its rated life ( 1,500 h ). The burner design allows for "Any" operating position and easy lamp replacement , optimizing maintenance time on tour or in fixed installations. (Data verified in the official OSRAM product data sheet.)
