Klieg lights. A Klieg light is an intense carbon arc lamp especially used in filmmaking.It is named after inventor John Kliegl and his brother Anton Kliegl.Klieg lights usually have a Fresnel lens with a spherical reflector or an ellipsoidal reflector with a lens train containing two plano-convex lenses or a single step lens.
An arc lamp or arc light is a lamp that produces light by an electric arc (also called a voltaic arc). The carbon arc light, which consists of an arc between carbon electrodes in air, invented by Humphry Davy in the first decade of the 1800s, was the first practical electric light .
[33] [29] The takeover of the incandescent lamp would be inexorable. [36] [37] [29] From about 1908, motion picture studios were using the company's floor-stand arc lamps, which allowed for point-source lighting, including some of the first low-light effects; the shadow produced by the two pairs of carbon rods can be seen in some early films.

The Xenon arc lamp was introduced in Germany in 1957 and in the US in 1963. After film platters became commonplace in the 1970s, Xenon lamps became the most common light source, as they could stay lit for extended periods of time, whereas a carbon rod used for a carbon arc could last for an hour at the most.
The arc then continues to burn, gradually consuming the carbon electrodes and the intervening plaster, which melts at the same pace. The first candles were powered by a Gramme machine . The drawback of using direct current was that one of the rods would burn at twice the rate of the other.

They can also move 'live' (with the lamp on), to achieve many of the effects used in modern productions. The majority of intelligent fixtures employ arc lamps as a light source, and therefore use a variety of mechanical methods to achieve the effect of dimming. Some fixtures employ standard halogen lamps.
An arclight or arc lamp is a lamp that produces a bright light by generating an electric arc across two electrodes. Arclight , Arc Light or arc light may also refer to: Arts and entertainment
