Portable Lights
Work lights from different eras.
On the right is a carbide lamp Invented in 1892. Carbide lamps are simple devices that produce and burn acetylene which is created by the reaction of calcium carbide with water.
Acetylene gas lamps like this one were worn on the hat or carried by hand and were widely used in mining in the early twentieth century.
To operate, calcium carbide is placed in a lower chamber called the generator. The upper reservoir is then filled with water. A threaded valve or other mechanism is used to control the rate at which the water is allowed to drip into the chamber containing the calcium carbide. The gas is ignited from a flint spark caused by turning the wheel on the reflector.
On the left are two LED flashlights. To operate, push a button.
