Ushio UXL-450S-O Xenon Short Arc Lamp (UXL-450SO) 

is a 450 watt high-pressure xenon short-arc discharge lamp engineered for applications that need very high arc luminance from a compact arc source and a daylight-like, well-balanced visible spectrum. UXL xenon short-arc lamps are widely used as precision illumination sources where stable output, rapid ignition, and repeatable optical performance matter.

Applications

Features

• Daylight-like visible output: near-continuous spectral distribution in the visible region for color rendering close to natural daylight.
• Very high luminance from a small arc: supports efficient coupling into optics, light guides, and measurement systems. 
• Fast ignition and quick stabilization: reaches stable operation rapidly compared with mercury arc sources. 
• Stable color vs. input variation: designed so color does not vary as a result of input power variation in typical operation. 
• Strong IR output: useful for IR radiation applications as well as visible illumination.

Specifications 

Specs shown are manufacturer-published and may change without notice. Confirm fit and operating conditions for your system before installation.

Usage notes:  

• Use the correct power supply / igniter: xenon short-arc lamps require suitable ignition and stable DC operation designed for the lamp type and wattage class.
• Use an appropriate lamp housing: operate in a proper enclosure intended for high-pressure xenon lamps.
• Handle with care: high-pressure lamps should be transported/stored appropriately and handled with protective measures during installation and removal.
• Safety reminder (high-pressure xenon): Xenon short-arc lamps operate at high pressure and produce intense optical radiation. Use proper PPE, follow lamp-house procedures, and allow adequate cool-down time before service.
