Ushio UXR-300BF - 300W (15V, 20A) Ceramic Xenon Lamp with Parabolic Reflector for Endoscopy and Microscopy
The Ushio UXR-300BF is a short-arc xenon lamp with a pre-aligned ceramic parabolic reflector designed for medical, scientific, and industrial light sources. It offers a continuous spectrum with a stable color temperature of 6100 K , superior luminous flux maintenance , and a window design that protects against scratches and contamination. Manufactured in an ISO- certified facility, it ensures lamp-to-lamp consistency and high reliability in demanding applications such as endoscopy , surgical lighting , microscopy , borescopy , spectroscopy , machine vision , solar simulation , and projection .
It operates at 300 W with 15 V and 20 A (range 18–21 A), delivering 4500 lm of visible output ( 1830 lm measured through a 5 mm aperture ) and 50 W of radiant output. It is ozone-free , requires forced cooling , and its operating position is horizontal . Mounting is achieved using a standard pattern of three 6-32 UN-2B threads at 120°, with a Ø25.4 mm window , a total length of 42.6 mm , and a body diameter of 32.8 mm .
