This steel mill uses a flint held against the rotating wheel "D", making sparks. (Matthias Dunn, Treatise on the Winning and Working of Collieries, 1852) The first mechanically powered portable illumination was the "steel mill", used in coal mining during the 1800s. These lamps consisted of a steel disk, rotated at high speed by a crank mechanism.
Some adapters for wall outlets use an Edison screw, allowing a light socket to become an ungrounded electrical outlet (such as to install Christmas lights temporarily via a porch light), or to make a pull-chain switch with two outlets, or to split it for two lamps. Another adapter can make a wall outlet into a lamp holder (lamp socket).
Many resembled lanterns, consisting of a battery box with a handle and the lamp and reflector attached to the front. Electric lanterns are used for lighting the broad area immediately around the lantern, as opposed to forming a narrow beam; they can be set down on a level surface or attached to supports.

A battery eliminator is an adapter intended to allow a device intended for battery operation, such as a radio, to be operated from an AC outlet. [15] All radios, except crystal sets, used inconvenient and messy vacuum tube batteries until the mid- to late-1920s. Battery eliminators that plugged into light sockets became very popular. [16]
A wedge base is a type of electrical connector used as a fitting for small light bulbs. It is similar to the bi-pin connector , except that the two "pins" are the same wires that extend into the bulb (rather than being rigid), and the wires are bent up onto the sides of the base, where they make contact with the socket.
A plug is the connector attached to an electrically-operated device, often via a cable. A socket (also known as a receptacle or outlet) is fixed in place, often on the internal walls of buildings, and is connected to an AC electrical circuit. Inserting ("plugging in") the plug into the socket allows the device to draw power from this circuit.
A light fixture (US English), light fitting (UK English), or luminaire is an electrical lighting device containing one or more light sources, such as lamps, and all the accessory components required for its operation to provide illumination to the environment. [1] All light fixtures have a fixture body and one or more lamps.
