Arc lamps and domestic electricity
Crompton's work with arc lamps began with Dennis & Co. Dissatisfied with the French lamps he was importing Crompton designed a lamp of his own based on the successful Serrin lamp. He placed the mechanism above the carbons so that it cast no downward shadow, and improved the regulating mechanism to reduce the amount of flickering. Crompton's design based upon the Pochin lamp produced one of the best arc lamps available.
He used his arc lamp design to develop the military searchlight. In 1880 he published one of the first lighting manuals, The Electric Light for Industrial Uses. In the same year, he met Joseph Swan and was impressed by Swan's incandescent lamp. Crompton and Swan worked together, their joint company installing both arc and filament lamps.
Using his own electric light design Crompton mounted spectacular demonstrations at the Henley Regatta and Alexandra Palace in 1879. His installations included the Windsor Castle, the Law Courts, King's Cross station as well as the Opera House and several other public buildings in Vienna.
Colonel Crompton took a strong interest in the development of the domestic use of electricity and worked closely with the Electrical Association of Women. Crompton & Co produced one of the first electric cookers. He was instrumental in the formation of the International Electrotechnical Commission in 1906 and in 1926 was awarded the Faraday Medal.
Crompton died 15 February 1940.
