The light is produced either directly by the flame, generally by using special mixes (typically propane or butane) of illuminating gas to increase brightness, or indirectly with other components such as the gas mantle or the limelight, with the gas primarily functioning to heat the mantle or the lime to incandescence. Before electricity became sufficiently widespread and economical to allow for general public use, gas lighting was prevalent for outdoor and indoor use in cities and suburbs where the infrastructure for distribution of gas was practical. At that time, the most common fuels for gas lighting were wood gas, coal gas and, in limited cases, water gas. Early gas lights were ignited manually by lamplighters, although many later designs are self-igniting. Gas lighting n ...
