OSRAM XBO R 300 W/60 C OFR - Short arc xenon lamp with reflector (backfocus 60 mm), daylight ~6,200 K, CRI ≥95

The OSRAM XBO R 300 W/60 C OFR is a short-arc xenon lamp with an elliptical reflector , designed to provide high-luminance point illumination with a continuous visible spectrum . It maintains a stable light color of approximately 6,200 K (daylight) and a CRI ≥95 throughout its lifespan, with excellent arc stability , instant start , hot restart , and wide dimming range . The OFR (ozone-free) version uses special quartz that prevents ozone formation . It features a dichroic reflector to reduce IR radiation directed at the object, a 60 mm backfocus , and requires forced cooling and DC operation.

Main features

• Power and electrical: 300 W nominal (operating range 200–310 W), 16–20 V at start, 18 A DC.
• Color and light quality: ~6,200 K (daylight), CRI Ra 95 , nominal flux 1,500 lm .
• Optics: dichroic elliptical reflector with working distance/backfocus 60 mm ; beam-to-axis max. ~30°.
• Construction and dimensions: Ø 82 mm (reflector), total length 106 mm , mounting length 80 mm , cable with connector ~150 mm , base FaXP2.5-2x65 , weight approx. 155 g .
• Operation: adjustable , hot restart , p20 working position , forced cooling .
• Useful life: 500 h nominal and up to 1,000 h average in horizontal position (manufacturer's reference conditions).
• Safety: OFR (ozone-free) version; operation in a closed housing with adequate protection against high luminance, UV and high internal pressure.

Product benefits

• Extreme luminance: ideal point source for fiber optic coupling and high-intensity projection.
• Constant color: daylight ~6,200 K and CRI ≥95 constant throughout its lifespan, favoring color fidelity in procedures and image capture.
• Stable and controllable arc: instant start, hot restart and wide dimming range to adjust the light output to the process.
• Improved thermal management: dichroic reflector that reduces IR on the illuminated object.

Use cases

• Medicine and science: endoscopy , microscopy , surgical headlamps , fiber optic illumination.
• Industry and R&D: imaging and scanning , small power solar simulation , high-demand visual inspection.

Equipment compatibility (verified examples)

Frequently used in 300W light sources for fiber optics and surgical microscopes. Documented examples include the ConMed/Linvatec LS7500 , Designs for Vision Daylite Xenon 300 , and Linvatec 7501 , as well as surgical microscopy systems (e.g., Zeiss Pentero), according to specialized distributor listings. Always verify the exact manufacturer's part number before purchasing.

Frequently Asked Questions

• Is it dimmable and does it support hot restrike? Yes, it's dimmable over a wide range and supports hot restrike , according to the technical specifications.
• Does it generate ozone? No, it's the OFR version with quartz that blocks the 185 nm line responsible for ozone formation.
• What type of cooling is required? Forced cooling (active ventilation) according to the manufacturer's instructions.
• Is it safe for open use? It must be operated in enclosed and protected housings . Open operation is only permitted with specific safety measures.

Installation and safety

• Operate only with compatible DC power supplies and respecting polarity , current 18 A and voltage 16–20 V at startup.
• Ensure forced cooling and ventilation of the compartment.
• Avoid any direct exposure to UV/IR and glare: high luminance and high internal pressure .
• Handle with appropriate PPE and protective covers supplied; do not touch the quartz.
