The High Power Arc in Motion Pictures

One of the greatest developments in Military illumination during the war was the High, Intensity Arc. In order to compete with the new methods of warfare both our Army and Navy found it necessary to demand searchlights of an intensity which had been considered unattainable. The ordinary carbon arc, such as had been used in searchlights for many years, could not be forced by any means to meet this urgent demand for more powerful searchlights. It was only the development of a new source of light which could fill this need. As was the case in many engineering branches of the service, necessity was the mother of invention, and so a new source of light was perfected and introduced into the searchlight field during those remarkable years of the war when a new development would be in common use by the Army or Navy before the public had even heard of its invention.
