Purpose and audience

The Ushio UXL-150S-O is a 150 W short-arc xenon lamp rated at 3000 lm with a 1200 h lifetime. It suits medical and scientific users who need a continuous daylight-like spectrum and strong colour rendering for imaging or inspection tasks.

Upgrade context

The lamp replaces older discharge sources that produce gaps in spectral output or shift colour over time. The jump is worth it when procedures demand consistent daylight approximation and reliable intensity across the full rated life.

Interface limits

The short-arc design concentrates light in a very small gap, which requires precise optical alignment and stable power delivery. Arc stability depends on a compatible ballast and proper cooling; without them the spectrum and lifetime cannot be maintained.

Questions about this item

What fixture dimensions or socket type does the 150 W short-arc xenon lamp require for proper mounting?

The UXL-150S-O is a short-arc xenon discharge lamp rated at 150 W; it must be installed in a compatible lampholder designed for its specific base and arc-tube geometry to ensure correct alignment and safe operation.

What is the correct installation procedure for the UXL-150S-O, and which step is most often done incorrectly?

Install the lamp only when cold, avoid touching the quartz envelope with bare hands, secure it firmly in the designated lampholder, and verify polarity if marked; the step most often missed is cleaning the envelope with alcohol after accidental contact to prevent hot spots and early failure.

When will the UXL-150S-O need replacement, and what maintenance is required before then?

The lamp is rated for 1200 hours of life at 3000 lumens output; no periodic maintenance is required other than ensuring the fixture's cooling and ventilation remain unobstructed, and replacement is needed once the rated hours are reached or light output degrades significantly.
