Light mast is a tall lighting specified[ clarification needed ] mast, which has several big searchlights on top of it. Light masts illuminates large areas and are possible to move, which is why they are used (for example) as farming, construction and emergency works implement. The device works with its own electric generator or with external power source.

An electric light is a device that produces visible light from electric current. It is the most common form of artificial lighting and is essential to modern society, providing interior lighting for buildings and exterior light for evening and nighttime activities. In technical usage, a replaceable component that produces light from electricity is called a lamp. Lamps are commonly called light bulbs; for example, the incandescent light bulb. Lamps usually have a base made of ceramic, metal, glass, or plastic, which secures the lamp in the socket of a light fixture. The electrical connection to the socket may be made with a screw-thread base, two metal pins, two metal caps or a bayonet cap.
An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light with a wire filament heated until it glows. The filament is enclosed in a glass bulb to protect the filament from oxidation. Current is supplied to the filament by terminals or wires embedded in the glass. A bulb socket provides mechanical support and electrical connections.
An arc lamp or arc light is a lamp that produces light by an electric arc. The carbon arc light, which consists of an arc between carbon electrodes in air, invented by Humphry Davy in the first decade of the 1800s, was the first practical electric light. It was widely used starting in the 1870s for street and large building lighting until it was superseded by the incandescent light in the early 20th century. It continued in use in more specialized applications where a high intensity point light source was needed, such as searchlights and movie projectors until after World War II. The carbon arc lamp is now obsolete for most of these purposes, but it is still used as a source of high intensity ultraviolet light.
Chiaroscuro, in art, is the use of strong contrasts between light and dark, usually bold contrasts affecting a whole composition. It is also a technical term used by artists and art historians for the use of contrasts of light to achieve a sense of volume in modelling three-dimensional objects and figures. Similar effects in cinema and photography also are called chiaroscuro.
A theatre lighting designer works with the director, choreographer, set designer, costume designer, and sound designer to create the lighting, atmosphere, and time of day for the production in response to the text, while keeping in mind issues of visibility, safety, and cost. The LD also works closely with the stage manager or show control programming, if show control systems are used in that production. Outside stage lighting, the job of a Lighting Designer can be much more diverse and they can be found working on rock and pop tours, corporate launches, art installations, or lighting effects at sporting events.
A navigation light, also known as a running or position light, is a source of illumination on a vessel, aircraft or spacecraft. Navigation lights give information on a craft's position, heading, and status. Their placement is mandated by international conventions or civil authorities. Navigation lights are not intended to provide illumination for the craft making the passage, only for other craft to be aware of it.
The Light Armoured Vehicle II Coyote is an armoured car built by General Dynamics Land Systems Canada for the Canadian Forces, for use in the light reconnaissance (scout) role. It was also initially used in the role of medium tank trainer within armoured cavalry squadrons in the same way as the AVGP Cougar it replaced. In service since 1996, the Coyote is a later generation of the LAV-25 and is of the same family as the Bison APC and the Australian ASLAV, as all are part of the Light Armoured Vehicle family produced by General Dynamics Land Systems - Canada and based on the MOWAG Piranha 8x8.
A moonlight tower or moontower is a lighting structure designed to illuminate areas of a town or city at night.
A light fixture, light fitting, or luminaire is an electrical device that contains an electric lamp that provides illumination. All light fixtures have a fixture body and one or more lamps. The lamps may be in sockets for easy replacement—or, in the case of some LED fixtures, hard-wired in place.
A candelabrum, sometimes called a candle tree, is a candle holder with multiple arms. The word comes from Latin.
A film still is a photograph taken on or off the set of a movie or television program during production. These photographs are also taken in formal studio settings and venues of opportunity such as film stars' homes, film debut events, and commercial settings. The photos were taken by studio photographers for promotional purposes. Such stills consisted of posed portraits, used for public display or free fan handouts, which are sometimes autographed. They can also consist of posed or candid images taken on the set during production, and may include stars, crew members or directors at work.
Aircraft warning lights are high-intensity lighting devices attached to tall structures as collision avoidance measures. Such devices make structures more visible to aircraft, and are usually used at night, although they may be used during the day. These lights need to be of sufficient brightness to be visible for miles around the structure.
The Bradleys Head Fortification Complex is a heritage-listed former mast and defensive battery and military fortification and now war memorial and recreational area located at Bradleys Head Road within the Sydney Harbour National Park in Mosman in the Mosman Council local government area of New South Wales, Australia. It was designed by Government engineers and built from 1840 to 1934. It is also known as Bradleys Head Forts and HMAS Sydney 1 Mast and Associated Memorials. The property is owned by the NSW Office of Environment and Heritage, an agency of the Government of New South Wales. It was added to the New South Wales State Heritage Register on 30 August 2010.
The Kurilpa Bridge is a A$63 million pedestrian and bicycle bridge over the Brisbane River in Brisbane, Queensland, Australia. The bridge connects Kurilpa Point in South Brisbane to Tank Street in the Brisbane central business district. In 2011, the bridge was judged World Transport Building of the Year at the World Architecture Festival.
A solar lamp also known as solar light or solar lantern, is a lighting system composed of a LED lamp, solar panels, battery, charge controller and there may also be an inverter. The lamp operates on electricity from batteries, charged through the use of solar photovoltaic panel.
An Austin ring transformer is a special type of isolation transformer used for providing power to the aircraft warning lights and other devices on a mast radiator antenna insulated from ground. In the Austin transformer the primary and secondary windings are separated by an air gap, so that the high voltage on the mast cannot get into the low voltage lighting supply wiring, causing safety hazards. It is named after its inventor, Arthur O. Austin, who graduated from Stanford University in 1903 and who obtained 225 patents in his career.

It has diversified with interests in lighting, luminaries, appliances, fans, LPG based Generators, engineering and projects.
High-mast lighting is a tall pole with lighting attached to the top pointing towards the ground, usually but not always used to light a highway or recreational field. It is used at sites that require lighting over a large area. The pole that the lighting is mounted on is generally at least 30 m (98 ft) tall, while the lighting consists of a luminaire ring surrounding the pole with one or several independent lighting fixtures mounted around it. Most units have four, six or eight lights in the ring, with three, five, ten, twelve and sixteen lights used in rarer instances. While most high-mast lights are high-pressure sodium, other types such as mercury vapor, metal halide and LED, have also been used. Some units have the lighting surrounded by a circular shield to prevent or reduce light pollution or light trespass from affecting neighbourhoods adjacent to the highway.
A light tower is a piece of mobile equipment which has one or more high-intensity electric lamps and a mast. Almost always, the lights are attached to the mast, which is attached to a trailer, with a generator set to power the lamps. Normally the lamps are metal halide bulbs and the generator is powered by a diesel engine. However, battery-powered, solar-powered and hydrogen-powered sets are available; light towers with electrodeless lamps lighting are also sold. Modular kits permit separation of the generator set, trailer, lights and mast from each other. Another variation is an inflatable mast. Particularly when an inflatable mast is used, the lights may be placed close to the ground, with a reflector attached to the mast. When soft lighting is wanted, an inflatable "balloon" diffuser may be used. An inflatable mast may serve as a diffuser.
