The Ushio UXL-150MO is a 150W short-arc xenon lamp designed as a high-intensity, continuous-spectrum , 6000K spot light source, ideal for spectroscopic analysis , microscopy , solar simulators , boroscopy , and machine vision . Its ozone-free quartz electrode reduces emission below 200nm, minimizing ozone generation in the equipment. It incorporates an improved electrode design and optimized manufacturing processes under ISO quality control, resulting in high arc stability and a lifespan of 1500 hours .
It operates at 17.5 ± 2 V DC with a rated current of 8.5 A (useful range 7–9 A) and offers a total luminous flux of 4000 lm and a horizontal intensity of 270 cd . The cold arc gap is 2.05 mm and the lamp weighs 51 g . It supports a vertical working position of ±5° , current ripple ≤ 3% pp , a minimum trip voltage of 35 kV AC , and a maximum base temperature of 200 °C . Forced cooling is not required according to the manufacturer's specifications. Its double-terminal construction with M4 threaded studs facilitates integration into standard lampholders.

Frequently Asked Questions
What does “ozone free” mean? It means that the quartz blocks deep UV radiation (<200 nm), preventing ozone generation inside the lamp housing. This simplifies ventilation and system maintenance.
Is it interchangeable with OSRAM XBO 150W/1? Often yes in 150W cases with vertical orientation and dual-terminal mounting, but always check sockets, orientation, power supply (trigger and ripple voltage) and the equipment manufacturer's specifications.
