OSRAM XBO 150 W/CR OFR - 150 W Short Arc Xenon Lamp, Double SFc12-4 (OFR) Socket

OSRAM XBO 150 W/CR OFR - 150 W Short Arc Xenon Lamp, Double SFc12-4 (OFR) Socket

The OSRAM XBO 150 W/CR OFR is a reflectorless (OFR, Ozone-Free ) short-arc xenon lamp designed for microscopy, endoscopy, surgical headlamps, fiber optic illumination, scanning, and scientific imaging . It delivers stable daylight at approximately 6,000 K with a CRI of 98 , very high luminance (approximately 20,000 cd/cm²) , and a luminous flux of 2,900 lm from a high-intensity point source ( 290 cd ), ensuring consistent contrast and colorimetry throughout its lifespan. It operates on direct current (DC) at 8.5 A and 15–18 V lamp voltage, supports hot-restart , and is dimmable over a wide range. Its double-ended construction incorporates SFc12-4 (anode +) and SFcX12-4 (cathode −) , with s15 burn position (vertical, anode up), forced cooling and compact dimensions: Ø 20 mm , length 150 mm , LCL 57 mm . Average lifetime: 3,000 h vertical / 1,200 h horizontal .

Frequently Asked Questions

• What is its lifespan? Reference life: 3,000 hours vertically and 1,200 hours horizontally (average). The nominal lifespan indicated by the manufacturer is 2,000 hours .
• Does it need cooling? Yes, it requires forced cooling to maintain adequate base temperatures.
• Is it dimmable and does it allow hot-restoring? Yes, it is dimmable and supports hot-restoring with the correct DC power supply.
• How should I orient it? Position s15 . In vertical position, the anode (+) should be at the top . In horizontal position, many devices require magnetic arc stabilization .

Installation and safety recommendations

• Use only in enclosed housings suitable for XBO lamps and with the supplied protective equipment .
• Check electrical compatibility: DC , 8.5 A , 15–18 V (≈150 W), polarity and ballast/rectifier type.
• Do not touch the bulb/electrodes; handle with face shield, cut-resistant gloves and protective jacket .
• Verify airflow and thermal limits of the equipment manufacturer; respect safety distances and interlocks.
