An acetylene gas miner's lamp. 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. Portable ...
A mining lamp is a lamp, developed for the rigid necessities of underground mining operations. ... Carbide lamp, a lamp that produces and burns acetylene;
Carbide lamps are still used for mining in some less wealthy countries, for example in the silver mines near Potosí, Bolivia. Carbide lamps are also still used by some cavers exploring caves and other underground areas, [ 17 ] although they are increasingly being replaced in this use by LED lights.
Coal miners wearing headlamps in 1946. At the end of the shift the lamps would be checked into the lamp house for recharging and maintenance. Carbide lamps were developed around 1900, and continued to be used after the introduction of battery lamps, which initially had poor battery life. Battery-powered headlamps with incandescent bulbs were ...
The Sussmann lamp [58] was introduced into Britain in 1893 and following trials at Murton Colliery in Durham it became a widely used electric lamp with 3000 or so reported by the company in use in 1900 [59] However, by 1910 there were only 2055 electric lamps of all types in use – about 0.25% of all safety lamps.

A similar disaster eighteen years later in Illinois, the 1932 Moweaqua Coal Mine disaster, helped spur efforts to end the legal use of flammable carbide-acetylene lamps in U.S. coal mines. The Eccles No. 5 mine resumed operations after the disaster, and continued in operation until 1928; the coal seam utilized by the mine continued to be ...
The carbide lamp was developed in the early 1900s. While the lamps proved useful in many applications, the problem of safely storing acetylene meant they needed regular refilling which constrained their use in applications such as lighthouses.
A flicker light bulb, flicker flame light bulb or flicker glow lamp is a gas-discharge lamp which produces light by ionizing a gas, usually neon mixed with helium and a small amount of nitrogen gas, by an electric current passing through two flame shaped electrode screens coated with partially decomposed barium azide. The ionized gas moves ...
