Film-set light, also known as Klieg light, is a type of bright, high-intensity artificial light used in filmmaking and television production. It is named after inventor John Klieg, who developed the first carbon arc lamp in the early 1900s. Klieg lights are typically used to provide a bright, even light for outdoor scenes or to create dramatic lighting effects indoors. They are also used to light large areas such as stages, sets, and studios.
