Xenon is the noble gas most commonly used in photographic flashguns and strobe lights. When an electric current is discharged through xenon gas, it produces a brief, intense flash of broadband white light, which is ideal for photography.
Xenon is used in flash lamps due to its ability to produce bright, white light upon electrical discharge.
