OSRAM SIRIUS HRI 140W RO - Discharge lamp with dichroic reflector for moving heads (Robe MiniPointe)

OSRAM SIRIUS HRI 140W RO - Discharge lamp with dichroic reflector for moving heads (Robe MiniPointe)

The OSRAM SIRIUS HRI 140W RO is a short-arc discharge lamp with an integrated reflector , designed for compact entertainment equipment such as moving heads , scanners , and effects. Its high-pressure, ultra-short-arc burner provides high luminance and a highly focused beam , with an initial luminous flux of 5400 lm , a color temperature of 9200 K , and a CRI of 60 for bright and penetrating effects. Originally designed as the official light source for the Robe MiniPointe , it is now also used in numerous projectors from various brands in the industry.

With a nominal power of 140 W , 70 V , and 1.9 A , it integrates a dichroic reflector for efficient thermal management and is optimized for electronic equipment (ECG) . The lamp offers an average lifespan of up to 6,000 hours , ignition at 2.5 kVp , a universal burn-in position , and requires forced cooling to ensure stability and performance throughout its lifespan.

Frequently Asked Questions

Is this the original lamp for the Robe MiniPointe? Yes, the SIRIUS HRI 140W RO was designed by OSRAM for the Robe MiniPointe .

Is the "working distance" 1.0 mm? No. 1.0 mm refers to the arc length . The lamp's optics have a focal length of approximately 37.7 mm , which is the relevant measurement for focusing on the projector.

Does it need a special ballast? Yes, it must work with electronic equipment (ECG) specified by the luminaire manufacturer.

Does it require ventilation? Yes, forced cooling is mandatory to ensure performance and lifespan.

Is it dimmable? Dimming depends on the luminaire's ECG design; always follow the manufacturer's instructions.

Installation and best practices

• Handle with clean gloves ; avoid touching the reflector or bulb.
• Verify 70 V / 1.9 A , 2.5 kVp ignition and ECG recommended by the appliance manufacturer.
• Respect the focal length and lamp seat for correct focusing.
• Always use enclosed accommodations with UV filtering and adequate ventilation.
