1. Overview

Xenon lighting refers to light sources utilizing xenon gas discharge to generate high-intensity illumination. These lamps produce light by passing electrical current through xenon gas under high pressure, creating a plasma arc between two electrodes. Known for their exceptional brightness (up to 300 lm/W), continuous spectrum (similar to natural sunlight), and rapid response times, xenon lamps are critical in applications requiring precise light control and high photometric performance. Their importance spans medical imaging, industrial metrology, automotive headlights, and entertainment lighting systems.
