OSRAM SIRIUS HRI 470W RO - Discharge lamp with reflector for moving heads (special Robe MegaPointe)

The OSRAM SIRIUS HRI 470W RO is a high-performance discharge lamp with an integrated reflector , specifically designed for compact moving head fixtures. It stands out for its high luminance thanks to a very short arc and high operating pressure, offering a color temperature of 7,500 K , a CRI of 80 , and a nominal luminous flux of 19,500 lm . Its optimized burner design allows for any working position and maintains stable light output throughout its lifespan. It is the original replacement for the Robe MegaPointe and is compatible with fixtures that use compatible electronic lighting components (ECGs).

With a rated power of 470 W , 83 V , and a rated current of 5.3 A (5.6 A in square wave operation), the SIRIUS HRI 470W RO offers an optimal balance between brightness, size, and durability ( average life 1,500 h ). Its compact dimensions ( max. length 67 mm , reflector diameter 60 mm , working distance 48 mm ) and easy replacement facilitate maintenance on tour and in fixed installations.
