An electric light, lamp, or light bulb is an electrical component that produces light. It is the most common form of artificial lighting. Lamps usually have a base made of ceramic, metal, glass, or plastic, which secures the lamp in the socket of a light fixture, which is often called a "lamp" as well. The electrical connection to the socket may be made with a screw-thread base, two metal pins, two metal caps or a bayonet mount.
Koninklijke Philips N.V., commonly shortened to Philips, is a Dutch multinational conglomerate corporation that was founded in Eindhoven in 1891. Since 1997, it has been mostly headquartered in Amsterdam, though the Benelux headquarters is still in Eindhoven. Philips was formerly one of the largest electronics companies in the world, but is currently focused on the area of health technology, having divested its other divisions.
A fluorescent lamp, or fluorescent tube, is a low-pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light. An electric current in the gas excites mercury vapor, which produces short-wave ultraviolet light that then causes a phosphor coating on the inside of the lamp to glow. A fluorescent lamp converts electrical energy into useful light much more efficiently than an incandescent lamp. The typical luminous efficacy of fluorescent lighting systems is 50–100 lumens per watt, several times the efficacy of incandescent bulbs with comparable light output. For comparison, the luminous efficacy of an incandescent bulb may only be 16 lumens per watt.
Stagecraft is a technical aspect of theatrical, film, and video production. It includes constructing and rigging scenery; hanging and focusing of lighting; design and procurement of costumes; make-up; stage management; audio engineering; and procurement of props. Stagecraft is distinct from the wider umbrella term of scenography. Considered a technical rather than an artistic field, it is primarily the practical implementation of a scenic designer's artistic vision.

Gas lighting is the production of artificial light from combustion of a fuel gas such as hydrogen, methane, carbon monoxide, propane, butane, acetylene, ethylene, coal gas or natural gas. The light is produced either directly by the flame, generally by using special mixes of illuminating gas to increase brightness, or indirectly with other components such as the gas mantle or the limelight, with the gas primarily functioning as a heat source for the incandescence of the gas mantle or lime.
A lighting control console is an electronic device used in theatrical lighting design to control multiple stage lights at once. They are used throughout the entertainment industry and are normally placed at the front of house (FOH) position or in a control booth.
In theatre, the master electrician is responsible for implementing the lighting design for a production drawn up by the lighting designer. This involves overseeing the preparation, hanging, connection and focusing of stage lighting fixtures.

A lighting control system incorporates communication between various system inputs and outputs related to lighting control with the use of one or more central computing devices. Lighting control systems are widely used on both indoor and outdoor lighting of commercial, industrial, and residential spaces. Lighting control systems are sometimes referred to under the term smart lighting. Lighting control systems serve to provide the right amount of light where and when it is needed.
Stage lighting instruments are used in stage lighting to illuminate theatrical productions, concerts, and other performances taking place in live performance venues. They are also used to light television studios and sound stages.

The Princess Theatre, originally Princess's Theatre, is a 1452-seat theatre in Melbourne, Victoria, Australia. Established in 1854 and rebuilt in 1886 to a design by noted Melbourne architect William Pitt, it is the oldest surviving entertainment site on mainland Australia. Built in an elaborate Second Empire style, it reflects the opulence of the "Marvellous Melbourne" boom period, and had a number of innovative features, including state of the art electric stage lighting and the world's first sliding ceiling, which was rolled back on warm nights to give the effect of an open-air theatre.

Track lighting is a method of lighting where light fixtures are attached anywhere on a continuous track device which contains electrical conductors. This is in contrast to directly routing electrical wiring to individual light positions. Tracks can either be mounted to ceilings or walls, lengthwise down beams, or crosswise across rafters or joists. They can also be hung with rods from especially high places like vaulted ceilings.
The control booth, control room, lighting box, technical booth, tech booth, or just booth used by television, film or theatrical technicians is the area designated for the operation of technical equipment, lighting controls and sound board. Often one or two followspots may be located in the booth as well. In a theater, it is generally an enclosed space with a large sliding window with a good view of the stage centered in the back of the house. It may be on the ground floor or at the balcony level. In a film or television production, it might be in a trailer or other space near the studio.
