OSRAM XBO 150 W/4 - Double-ended short-arc xenon lamp for fluorometry, microscopy and fiber guidance

The OSRAM XBO 150 W/4 is a 150 W short -arc xenon lamp with a dual-terminal connection, distinguished by its very high luminance and point source performance. It provides daylight (~6000 K) with a color rendering index (CRI) > 95 and consistent color throughout its lifespan, making it a reference solution for fluorometers, microscopy, endoscopy, scanning, and other scientific instrumentation . It utilizes special SUPRASIL quartz glass for increased transmission below 250 nm compared to conventional quartz, which is beneficial in optical systems and controlled UV excitation.

Designed for operation with direct current (DC) and specific power supplies, it delivers 3,000 lm of luminous flux, 300 cd of intensity, and a luminance of 15,000 cd/m² . It supports hot-swappable lighting , is dimmable over a wide range, and offers a rated life of 1,200 hours . Its compact design ( length 150 mm , Ø 20 mm , weight 100 g ) and SFc12-4 (anode) and SFcX12-4 (cathode) bases facilitate integration into professional fixtures and housings with forced cooling .

Frequently Asked Questions

Do they require a specific power supply? Yes. These lamps operate with DC power supplies and high-voltage ignition (igniter) designed for XBO. They are not compatible with halogen lamp ballasts or direct AC power.

Is UV radiation safe? The lamp emits UV and operates at high internal pressure . It must be used in suitable enclosed spaces and with the protective equipment specified by the manufacturer.

How is it installed? Respect the s15 position (anode up) , the tightening torque recommended by the equipment manufacturer and ensure forced cooling .

Can it be regulated? Yes, within the range allowed by the compatible DC power supply, while maintaining arc stability and ventilation.

Safety and best practices

• Always handle with protective jackets/gloves and goggles; do not touch the quartz.
• Use enclosed accommodations with filters and interlocks according to regulations.
• Check polarity (anode/cathode) , current 7.5 A , voltage 17…21 V DC and the LCL when centering the lamp.
