OSRAM SIRIUS HRI 330 W X8 - Discharge lamp with reflector for moving heads (8,000 K, 18,000 lm)
The OSRAM SIRIUS HRI 330 W X8 is a very short arc discharge lamp with an integrated reflector , developed for moving lights and entertainment projectors that require very high luminance , a focused beam , and stable output throughout its lifespan. It delivers a nominal luminous flux of 18,000 lm with a color temperature of 8,000 K and a CRI of 85 , operating at 330 W ( 75 V , 4.4 A ). Its optimized burner design allows for any firing position and facilitates quick replacement in compact luminaires. With a diameter of 58 mm and a length of 66 mm , an electrode gap of 1.0 mm , and a working distance of 37.4 mm , it integrates precisely into beam/spot optics for bright lighting effects . Nominal lifespan: 1,500 h .
