Product Description
150W xenon short-arc lamp designed as a compact, high-luminance source for UV-oriented optical systems and precision illumination.
 
Overview

The Ushio UXL-150S is a 150W xenon short-arc lamp engineered for systems that need a small, intense arc that couples efficiently into reflectors, lenses, or fiber inputs. This model is listed in the UXL family as Xenon Short Arc for UV and is commonly qualified by item code, burn position, and critical geometry such as arc gap and light center length (LCL). SKU: UXL-150S (5000325).

Key Highlights
  • Lamp Type: Xenon short arc (high-pressure discharge)
  • Electrical: 150W • 20V • 7.5A
  • Arc Gap: 2.5 mm (compact source for optical collection)
  • Output: 3000 lm (initial / luminous flux)
  • Rated Life: 1200 hours
  • Burn Position: V5
  • Geometry: 19.0 mm dia • 150 mm MOL • 58 mm LCL • 125 mm contact-to-contact
  • Bulb Finish: Clear
  • Front Glass Cover: No
Typical Applications
  • UV-oriented illumination systems that specify UXL-150S by code and geometry
  • Optical instruments and inspection platforms where arc stability supports repeatable measurements
  • Specialty scanners and precision light sources requiring V5 operating orientation
Compare & Contrast (Substitution Rules)
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. When comparing similar 150W xenon short-arc models, match arc gap (2.5 mm), LCL (58 mm), contact-to-contact (125 mm), and MOL (150 mm) before considering alternates.
Handling Tip
Xenon short-arc lamps are high-pressure glass products. Avoid impact, scratching, or excessive stress. Always follow the equipment manufacturer’s cool-down, shielding, and service procedure.
Industry Update (Ushio & ENI Continuity)
ams OSRAM announced the sale of its Entertainment & Industry Lamps (ENI) business to Ushio, with the transaction expected to close by the end of March 2026. During transitions, customers may see branding, labeling, or packaging changes across some legacy lamp lines. SOSCleanroom will continue to supply and support specialty lamps and can help validate continuity by part number and critical specs.

Science: Xenon Short Arc (Why It’s Used)

Xenon short-arc lamps are high-pressure discharge sources. Light is produced by an electrical arc between precisely designed electrodes inside a sealed envelope filled with xenon gas. The defining advantage is a very small, high-luminance arc that behaves like a near point-source, enabling efficient optical collection and repeatable coupling into reflectors, lenses, or fiber optics.

For system performance, arc gap (2.5 mm) and LCL (58 mm) are “focus” dimensions. If either changes, the focal point shifts, which can alter irradiance uniformity and measurement repeatability—especially in UV-oriented optical paths.

Replacement Qualification Checklist
Match these before substituting:
  • Item Code / SKU: 5000325
  • Electrical: 20V • 7.5A • 150W
  • Arc Geometry: 2.5 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 high-pressure devices. Do not bump, scratch, or apply stress to the lamp. Keep required fixture shielding in place, allow full cool-down before service, and follow the equipment OEM’s interlock and replacement procedure. Replace at or before rated life.
