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

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

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 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).
