OSRAM XBO R 100 W/45 OFR - Short arc xenon lamp with reflector (45 mm), 6,000 K and Ra 98 for fiber optics, endoscopy and microscopy

The Osram XBO R 100 W/45 OFR is a short-arc xenon lamp with an integrated reflector and a 45 mm focal length , designed for medical and scientific applications requiring a point source of very high luminance and stable color . It operates on direct current (DC) , with a lamp voltage of 12–14 V (13 V nominal) and a current of 7.0–7.4 A , offering a nominal luminous flux of 530 lm , a color temperature of 6,000 K , and a color rendering index (CRI) of Ra 98. It features hot-restart capability , is dimmable over a wide range, and maintains constant color throughout its lifespan (up to 500 hours ). It has a diameter of 64 mm , a length of 93 mm , and weighs 110 g ; it requires forced cooling and must be operated in enclosed housings. The OFR designation indicates an ozone-free version.

Outstanding compatibility

Commonly used as a replacement in the Roche LightCycler 480 real-time PCR system (13V/100W xenon lamp with reflector; see manufacturer's references and instrument manual).

Installation and safety recommendations

• Operate only in enclosed equipment designed for XBO lamps, with appropriate interlocks and UV protection.
• Power with a stabilized DC source ; do not exceed the nominal current (≈7.2 A) .
• Respect the 45mm focal length and mounting geometry for correct focusing on fiber optics.
• Handle with gloves ; the lamp maintains high internal pressure in both cold and hot conditions.
• Plan preventive replacement according to service hours or irradiance drop.
