Illuminating gas was used for gas lighting, as it produces a much brighter light than natural gas or water gas. Illuminating gas was much less toxic than other forms of coal gas, but less could be produced from a given quantity of coal. The experiments with distilling coal were described by John Clayton in 1684.
The threat from electrical light in the later 1870s and 1880s drove this trend strongly. The gas industry did not cede the gas lighting market to electricity immediately, as the invention of the Welsbach mantle, a refractory mesh bag heated to incandescence by a mostly non-luminous flame within, dramatically increased the efficiency of gas ...

A carbide lamp or acetylene gas lamp is a simple lamp that produces and burns acetylene (C 2 H 2), which is created by the reaction of calcium carbide (CaC 2) with water (H 2 O). [ 1 ] Acetylene gas lamps were used to illuminate buildings, as lighthouse beacons, and as headlights on motor-cars and bicycles.
