OSRAM SIRIUS HRI 280 W RO - Discharge lamp with reflector for Robe Pointe and moving heads (11,500 lm, 7,800 K, arc 0.9 mm)

OSRAM SIRIUS HRI 280 W RO - Discharge lamp with reflector for Robe Pointe and moving heads (11,500 lm, 7,800 K, arc 0.9 mm)

The OSRAM SIRIUS HRI 280 W RO is a metal halide discharge lamp with an integrated reflector , designed to deliver extremely high luminance and a highly concentrated beam in compact moving heads . This RO (customized) version is the approved reference for the Robe Pointe and is also used in numerous fixtures from other manufacturers. It provides 11,500 lm with a color temperature of 7,800 K and a CRI of 78 , maintaining a stable output throughout its rated life of 2,000 h . Its ultra-short arc of 0.9 mm and working distance (a) of 34.5 mm facilitate optical coupling in BEAM/SPOT/WASH systems. It operates at 70 V / 4 A , can be used in any position , and requires forced cooling . Assembly diameter: 51 mm ; length: 54.5 mm ; weight approx.: 65 g . For use only in enclosed luminaires with suitable filters.

Differences compared to SIRIUS HRI 280 W (non-RO)

• Both share electrical and photometric specifications ( 280 W, 70 V, 4 A, 11,500 lm, 7,800 K, CRI 78 ), arc 0.9 mm and working distance a = 34.5 mm according to current data sheets.
• The RO version is a customized model used by Robe and specifically referenced for the Pointe .

Frequently Asked Questions

• Does the working position matter? No; the burner design allows for any position .
• Does it need cooling? Yes, forced cooling according to the luminaire specifications.
• How does it affect lifespan? Irradiance and startup degrade with hours; plan for preventative changes around 2,000 hours or according to the equipment maintenance software.
• Safety recommendations? Operate only in closed enclosures with UV filtering; contains mercury: waste disposal in accordance with regulations.
