Ushio UXR-175BF Z1 - 175W (12.5V) Ozone-Free Ceramic Xenon Lamp with Parabolic Reflector for Endoscopy and Scientific Lighting
The Ushio UXR-175BF is a short-arc xenon lamp with a pre-aligned ceramic parabolic reflector designed to deliver continuous spectral output and stable color at 6100 K , with superior lumen maintenance and lamp-to-lamp repeatability. Its protected front window minimizes scratches and contamination, and the compact metal-ceramic body ensures robustness in demanding environments. Operating at 175 W with 12.5 V DC and a nominal current of 14 A (range 12.5–16 A), it offers 1900 lm of visible output ( 950 lm through a 5 mm aperture) and a total radiation of 30 W. It is ozone-free and requires a horizontal working position with forced cooling .
It is indicated for endoscopy , surgical lighting , microscopy , borescopy , spectroscopy , machine vision , solar simulation , and projection . The standard geometry ( 25.4 mm window diameter , 42.6 mm overall length , 32.8 mm body diameter , 1.1 mm arc gap ) and the 3× 6-32 UN-2B threaded mounting pattern at 120° facilitate its integration into numerous 175 W power supplies used in medical and industrial environments.

Frequently Asked Questions
Is this version “ozone-free”? Yes. The UXR-175BF is specified with an ozone-free spectrum , reducing <200 nm emissions and ozone generation within the housing.
Does it replace PE175BF? In many systems, yes. They share power (175 W), horizontal orientation, 25.4 mm window, and 3-hole mounting pattern; always verify the mechanical and electrical compatibility of your equipment.
