Gas lighting refers to a technology used to produce light from a gaseous fuel including hydrogen, methane, carbon monoxide, propane, butane, or ethylene.
Before electricity became sufficiently widespread and economical to allow for general public use, gas was the most popular means of lighting in cities and suburbs. Early gas lights had to be lit manually, but soon gas lights could light themselves.
Gas lighting today is typically used for camping, where the high energy density of a hydrocarbon fuel, combined with the modular nature of canisters allows bright and long lasting light to be produced cheaply and without complex equipment.
