Product Description
High-pressure xenon short-arc lamp with a compact arc for daylight-like output and stable optical performance.
 
Overview

The Ushio UXL-S150MO is a 150W xenon short-arc lamp engineered for systems that depend on a small, intense arc (tight arc gap) to achieve high luminance and repeatable optical coupling into reflectors, lenses, or fiber inputs. It is widely specified in scientific/medical instrumentation and inspection platforms where spectral balance and arc stability are critical. SKU: UXL-S150MO (5000375).

Key Highlights
  • Lamp Type: Xenon short arc (high-pressure discharge)
  • Electrical: 150W • 17.5V • 8.5A
  • Arc Gap: 2.1 mm (compact “point-like” source behavior)
  • Color Temperature: 6000K (daylight-like)
  • Output: 2900 lm • 290 cd (listed candle power)
  • Rated Life: 3000 hours
  • Geometry: 19.0 mm dia • 150 mm MOL • 58 mm LCL • 125 mm contact-to-contact
  • Burn Position: V5 (vertical orientation tolerance per equipment design)
  • Front Glass Cover: No
Typical Applications
  • Spectroscopic analysis and optical measurement systems
  • Microscopy and machine-vision illumination where a stable arc improves repeatability
  • Solar simulators, inspection tools, and specialty scanners specified by item code and arc geometry
Compare & Contrast (How to Substitute Safely)
Xenon short-arc lamps are not “swap by wattage.” Optical performance depends on arc gap, LCL, contact spacing, and the fixture’s designed burn position. If you are comparing UXL variants (including similar 150W models), match arc gap (2.1 mm), LCL (58 mm), contact-to-contact (125 mm), and MOL (150 mm) before considering any alternate codes.
Handling Tip
Xenon short-arc lamps are glass products filled with high-pressure gas. Avoid impact, scratching, or excessive stress. Never open the lamp housing during operation or immediately after shutoff—allow full cool-down per equipment procedure.
Industry Update (Ushio & ENI Continuity)
Ushio has an agreement to acquire ams OSRAM’s Entertainment & Industry Lamps (ENI) business, with closing expected by the end of March 2026. Customers may see branding, labeling, or packaging changes during transitions. SOSCleanroom will continue to supply and support specialty lamps and can help validate continuity by part number and critical specs.

Science: Why Xenon Short Arc is Used

UXL-series lamps are high-pressure xenon discharge sources. Their defining feature is a very small, high-luminance arc created between precisely positioned electrodes. The compact arc can be efficiently collected and imaged, which is why xenon short-arc lamps are common in scientific/medical and inspection systems where stability and repeatability matter.

In practical terms, arc gap and LCL are the “focus” dimensions. If these shift, the optical system’s focal point shifts, changing intensity distribution and alignment. The UXL-S150MO is designed with electrode geometry intended to support high arc stability and extended life.

Replacement Qualification Checklist
Before substituting any xenon short-arc lamp, match:
  • Item Code / SKU: 5000375
  • Electrical: 17.5V • 8.5A • 150W
  • Arc Geometry: 2.1 mm arc gap
  • Optical Reference: LCL 58 mm
  • Mechanical: 150 mm MOL • 125 mm contact spacing • 19.0 mm diameter
  • Operating: Burn position V5 per equipment design
Safety & Handling (High-Pressure Lamp)
Xenon short-arc lamps are filled with high-pressure gas. Do not bump, scratch, or apply stress to the lamp. Do not open the lamp housing during operation or until properly cooled. Replace the lamp at or before rated life, as risk of breakage can increase beyond rated hours. Always follow the equipment OEM’s shielding, interlock, and service procedures.
Industry Update (Ushio + ams OSRAM ENI)
Ushio has an agreement to acquire ams OSRAM’s Entertainment & Industry Lamps (ENI) business, with closing expected by the end of March 2026. Customers may see branding/packaging transitions across some legacy lamp lines during and after integration. SOSCleanroom will continue supporting specialty lamps and can assist with continuity validation by part number and critical specs.
