It produces a bright white light to simulate sunlight, with applications in movie projectors in theaters, in searchlights, and for specialized uses in industry and research.

- Xenon arc lamp

It continued in use in more specialized applications where a high intensity point light source was needed, such as searchlights and movie projectors until after World War II.

- Arc lamp

Xenon arc lamps can be roughly divided into three categories: continuous-output xenon short-arc lamps, continuous-output xenon long-arc lamps, and xenon flash lamps (which are usually considered separately).

- Xenon arc lamp

The xenon arc lamp, which produces a high intensity white light, is now used in many of the applications which formerly used the carbon arc, such as movie projectors and searchlights.

- Arc lamp

In the early 1900s up until the late 1960s, carbon arc lamps were the source of light in almost all theaters in the world.

- Movie projector

The Xenon arc lamp was introduced in Germany in 1957 and in the US in 1963.
