What is a Xenon Light Source used for?

Xenon is a colorless, odorless, and tasteless gas that is about 4.5 times heavier than air. It was also the first noble found to form true compounds. Today it is used in specialized light sources due to its ability to establish an arc between electrodes at low temperatures. Because of this property, a Xenon light source can produce higher light intensities. It produces a blue light glow and is used as high-speed electronic flash bulbs in photography, sunlight simulation devices in food processing and preparation, and ruby lasers, among other applications.
