Xenon torches

Xenon lamp

— this term can mean two types of light sources: one of the modifications of an incandescent lamp (see the relevant paragraph), where the bulb with a spiral is filled with xenon inert gas, or a gas discharge lamp, in which the light source is an electric arc in the same xenon medium. The first variety was used mainly in small pocket flashlights, the second — in hand lamps.

At one time, xenon lamps (both varieties) had very decent indicators of efficiency and brightness, although they were not cheap. However, again, the development of LEDs has made the production of flashlights with such lamps impractical, and this option is becoming less and less common nowadays.
