Gas lighting is production of artificial light from combustion of a gaseous fuel, such as hydrogen, methane, carbon monoxide, propane, butane, acetylene, ethylene, or natural gas.

Combustion High-temperature exothermic redox chemical reaction between a fuel (the reductant) and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke

Combustion, or burning, is a high-temperature exothermic redox chemical reaction between a fuel and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke. Combustion in a fire produces a flame, and the heat produced can make combustion self-sustaining. Combustion is often a complicated sequence of elementary radical reactions. Solid fuels, such as wood and coal, first undergo endothermic pyrolysis to produce gaseous fuels whose combustion then supplies the heat required to produce more of them. Combustion is often hot enough that incandescent light in the form of either glowing or a flame is produced. A simple example can be seen in the combustion of hydrogen and oxygen into water vapor, a reaction commonly used to fuel rocket engines. This reaction releases 242 kJ/mol of heat and reduces the enthalpy accordingly :

Hydrogen Chemical element with atomic number 1

Hydrogen is the chemical element with the symbol H and atomic number 1. With a standard atomic weight of 1.008, hydrogen is the lightest element in the periodic table. Hydrogen is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass. Non-remnant stars are mainly composed of hydrogen in the plasma state. The most common isotope of hydrogen, termed protium, has one proton and no neutrons.

Methane simplest organic molecule with one carbon atom and four hydrogen

Methane (or ) is a chemical compound with the chemical formula CH4 (one atom of carbon and four atoms of hydrogen). It is a group-14 hydride and the simplest alkane, and is the main constituent of natural gas. The relative abundance of methane on Earth makes it an attractive fuel, although capturing and storing it poses challenges due to its gaseous state under normal conditions for temperature and pressure.

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 fuel source.

Gas mantle

An incandescent gas mantle, gas mantle or Welsbach mantle is a device for generating bright white light when heated by a flame. The name refers to its original heat source in gas lights, which filled the streets of Europe and North America in the late 19th century, mantle referring to the way it is hung above the flame. Today it is still used in portable camping lanterns, pressure lanterns and some oil lamps.

Limelight type of stage lighting once used in theatres and music halls

Limelight is a type of stage lighting once used in theatres and music halls. An intense illumination is created when an oxyhydrogen flame is directed at a cylinder of quicklime, which can be heated to 2,572 °C (4,662 °F) before melting. The light is produced by a combination of incandescence and candoluminescence. Although it has long since been replaced by electric lighting, the term has nonetheless survived, as someone in the public eye is still said to be "in the limelight". The actual lights are called "limes", a term which has been transferred to electrical equivalents.

Before electricity became sufficiently widespread and economical to allow for general public use, gas was the most popular method of outdoor and indoor lighting in cities and suburbs. Early gas lights were ignited manually, but many later designs are self-igniting.

Electricity Physical phenomena associated with the presence and flow of electric charge

Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. In early days, electricity was considered as being not related to magnetism. Later on, many experimental results and the development of Maxwell's equations indicated that both electricity and magnetism are from a single phenomenon: electromagnetism. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others.

Suburb Human settlement that is part of or near to a larger city

A suburb is a mixed-use or residential area, existing either as part of a city or urban area or as a separate residential community within commuting distance of a city. In most English-speaking countries, suburban areas are defined in contrast to central or inner-city areas, but in Australian English and South African English, suburb has become largely synonymous with what is called a "neighborhood" in other countries and the term extends to inner-city areas. In some areas, such as Australia, India, China, New Zealand, the United Kingdom, and parts of the United States and Canada, new suburbs are routinely annexed by adjacent cities. In others, such as Saudi Arabia, France, and much of the United States and Canada, many suburbs remain separate municipalities or are governed as part of a larger local government area such as a county. In the United States, beyond the suburbs are exurbs, or "exurban areas", with less density but linked to the metropolitan area economically and by commuters.

Gas lighting today is generally used for camping, where the high energy density of a hydrocarbon fuel, combined with the modular nature of canisters (a strong metal container) allows bright and long lasting light to be produced cheaply and without complex equipment. In addition, some urban historical districts retain gas street lighting, and gas lighting is used indoors or outdoors to create or preserve a nostalgic effect.

Camping outdoor recreational activity

Camping is an outdoor activity involving overnight stays away from home in a shelter, such as a tent. Typically participants leave developed areas to spend time outdoors in more natural ones in pursuit of activities providing them enjoyment. To be regarded as "camping" a minimum of one night is spent outdoors, distinguishing it from day-tripping, picnicking, and other similarly short-term recreational activities. Camping can be enjoyed through all four seasons.

Energy density is the amount of energy stored in a given system or region of space per unit volume. Colloquially it may also be used for energy per unit mass, though the accurate term for this is specific energy. Often only the useful or extractable energy is measured, which is to say that inaccessible energy is ignored. In cosmological and other general relativistic contexts, however, the energy densities considered are those that correspond to the elements of the stress–energy tensor and therefore do include mass energy as well as energy densities associated with the pressures described in the next paragraph.

Early lighting fuels consisted of olive oil, beeswax, fish oil, whale oil, sesame oil, nut oil, and similar substances. These were the most commonly used fuels until the late 18th century. Chinese records dating back 1,700 years note the use of natural gas in the home for light and heat via bamboo pipes to the dwellings. [1] The ancient Chinese of the Spring and Autumn period made the first practical use of natural gas for lighting purposes around 500 B.C. where they used bamboo pipelines to transport and carry both brine and natural gas for many miles. [2] [3] [4] [5] [6]

Olive oil fat obtained by pressing olives

Olive oil is a liquid obtained from olives, a traditional tree crop of the Mediterranean Basin. The oil is produced by pressing whole olives. It is commonly used in cooking, whether for frying or as a salad dressing. It is also used in cosmetics, pharmaceuticals, and soaps, and as a fuel for traditional oil lamps, and has additional uses in some religions. There is limited evidence of its possible health benefits. The olive is one of three core food plants in Mediterranean cuisine; the other two are wheat and grapes. Olive trees have been grown around the Mediterranean since the 8th millennium BC.

Beeswax chemical compound

Beeswax is a natural wax produced by honey bees of the genus Apis. The wax is formed into scales by eight wax-producing glands in the abdominal segments of worker bees, which discard it in or at the hive. The hive workers collect and use it to form cells for honey storage and larval and pupal protection within the beehive. Chemically, beeswax consists mainly of esters of fatty acids and various long-chain alcohols.

Fish oil oil derived from the tissues of oily fish

Fish oil is oil derived from the tissues of oily fish. Fish oils contain the omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), precursors of certain eicosanoids that are known to reduce inflammation in the body and improve hypertriglyceridemia. There has been a great deal of controversy in recent years about the role of fish oil in cardiovascular disease, with recent meta-analyses reaching different conclusions about its potential impact. The most promising evidence supports supplementation for prevention of cardiac death.

Public illumination preceded the discovery and adoption of gaslight by centuries. In 1417, Sir Henry Barton, Lord Mayor of London, ordained "lanterns with lights to be hung out on the winter evenings between Hallowtide and Candlemasse." Paris was first lit by an order issued in 1524, and, in the beginning of the 16th century, the inhabitants were ordered to keep lights burning in the windows of all houses that faced the streets. In 1668, when some regulations were made for improving the streets of London, the residents were reminded to hang out their lanterns at the usual time, and, in 1690, an order was issued to hang out a light, or lamp, every night as soon as it was dark, from Michaelmas to Christmas. By an Act of the Common Council in 1716, all housekeepers, whose houses faced any street, lane, or passage, were required to hang out, every dark night, one or more lights, to burn from six to eleven o'clock, under the penalty of one shilling as a fine for failing to do so.

The Lord Mayor of London is the City of London's mayor and the leader of the City of London Corporation. Within the City, the Lord Mayor is accorded precedence over all individuals except the sovereign and retains various traditional powers, rights and privileges, including the title and style The Right Honourable the Lord Mayor of London.

All Saints Day Christian feast day

All Saints' Day, also known as All Hallows' Day, Hallowmas, the Feast of All Saints, or Solemnity of All Saints, is a Christian festival celebrated in honour of all the saints, known and unknown. In Western Christianity, it is celebrated on 1 November by the Roman Catholic Church, the Anglican Communion, the Methodist Church, the Church of the Nazarene, the Lutheran Church, the Reformed Church, and other Protestant churches. The Eastern Orthodox Church and associated Eastern Catholic Churches and Byzantine Lutheran Churches celebrate it on the first Sunday after Pentecost. Oriental Orthodox churches of Chaldea and associated Eastern Catholic churches celebrate All Saints' Day on the first Friday after Easter.

In coal mining, accumulating and escaping gases were known originally for their adverse effects rather than their useful qualities. Coal miners described two types of gases, one called the choke damp and the other fire damp . In 1667, a paper detailing the effects of these gases was entitled, "A Description of a Well and Earth in Lancashire taking Fire, by a Candle approaching to it. Imparted by Thomas Shirley, Esq an eye-witness."

Stephen Hales was the first person who procured a flammable fluid from the actual distillation of coal. His experiments with this object are related in the first volume of his Vegetable Statics, published in 1726. From the distillation of "one hundred and fifty-eight grains [10.2 g] of Newcastle coal, he states that he obtained one hundred and eighty cubic inches [2.9 L] of air, which weighed fifty-one grains [3.3 g], being nearly one third of the whole." These results seemed to have passed without notice for several years.

In the Philosophical Transactions of the Royal Society in 1733, some properties of coal-gas are detailed in a paper called, "An Account of the Damp Air in a Coal-pit of Sir James Lowther, sunk within Twenty Yards of the Sea." This paper contained some striking facts relating to the flammability and other properties of coal-gas.

The principal properties of coal-gas were demonstrated to different members of the Royal Society, and showed that after keeping the gas some time, it still retained its flammability. The scientists of the time still saw no useful purpose for it.

John Clayton, in an extract from a letter in the Philosophical Transactions for 1735, calls gas the "spirit" of coal and discovered its flammability by an accident. This "spirit" happened to catch fire, by coming in contact with a candle as it escaped from a fracture in one of his distillatory vessels. By preserving the gas in bladders, he entertained his friends, by exhibiting its flammability.

It took many years of development and testing before gas lighting for the stage was commercially available. Gas technology was then installed in just about every major theatre in the world. But gas lighting was short-lived because the electric light bulb soon followed.

It took nearly 200 years for gas to become accessible for commercial use. A Flemish alchemist, Jan Baptista van Helmont, was the first person to formally recognize gas as a state of matter. He would go on to identify several types of gases, including carbon dioxide. Over one hundred years later in 1733, Sir James Lowther had some of his miners working on a water pit for his mine. While digging the pit they hit a pocket of gas. Lowther took a sample of the gas and took it home to do some experiments. He noted, "The said air being put into a bladder … and tied close, may be carried away, and kept some days, and being afterwards pressed gently through a small pipe into the flame of a candle, will take fire, and burn at the end of the pipe as long as the bladder is gently pressed to feed the flame, and when taken from the candle after it is so lighted, it will continue burning till there is no more air left in the bladder to supply the flame." [7] Lowther had basically discovered the principle behind gas lighting.

Later in the 18th century William Murdoch stated: "the gas obtained by distillation from coal, peat, wood and other inflammable substances burnt with great brilliancy upon being set fire to … by conducting it through tubes, it might be employed as an economical substitute for lamps and candles." [8] Murdoch’s first invention was a lantern with a gas-filled bladder attached to a jet. He would use this to walk home at night. After seeing how well this worked he decided to light his home with gas. In 1797, Murdoch would install gas lighting into his new home as well as the workshop in which he worked. “This work was of a large scale, and he next experimented to find better ways of producing, purifying, and burning the gas.” [9] The foundation had been laid for companies to start producing gas and other inventors to start playing with ways of using the new technology.

William Murdoch (sometimes spelled "Murdock") was the first to exploit the flammability of gas for the practical application of lighting. He worked for Matthew Boulton and James Watt at their Soho Foundry steam engine works in Birmingham, England. In the early 1790s, while overseeing the use of his company's steam engines in tin mining in Cornwall, Murdoch began experimenting with various types of gas, finally settling on coal gas as the most effective. He first lit his own house in Redruth, Cornwall in 1792. [10] In 1798, he used gas to light the main building of the Soho Foundry and in 1802 lit the outside in a public display of gas lighting, the lights astonishing the local population. One of the employees at the Soho Foundry, Samuel Clegg, saw the potential of this new form of lighting. Clegg left his job to set up his own gas lighting business, the Gas Lighting and Coke Company.

A "thermolampe" using gas distilled from wood was patented in 1799, whilst German inventor Friedrich Winzer (Frederick Albert Winsor) was the first person to patent coal-gas lighting in 1804.

In 1801, Phillipe Lebon of Paris had also used gas lights to illuminate his house and gardens, and was considering how to light all of Paris. In 1820, Paris adopted gas street lighting.

In 1804, Dr Henry delivered a course of lectures on chemistry, at Manchester, in which he showed the mode of producing gas from coal, and the facility and advantage of its use. Dr Henry analyzed the composition and investigated the properties of carburetted hydrogen gas (i.e. methane). His experiments were numerous and accurate and made upon a variety of substances; having obtained the gas from wood, peat, different kinds of coal, oil, wax, etc, he quantified the intensity of the light from each source.

Josiah Pemberton, an inventor, had for some time been experimenting on the nature of gas. A resident of Birmingham, his attention may have been roused by the exhibition at Soho. About 1806, he exhibited gas lights in a variety of forms and with great brilliance at the front of his factory in Birmingham. In 1808 he constructed an apparatus, applicable for several uses, for Benjamin Cooke, a manufacturer of brass tubes, gilt toys, and other articles.

In 1808, Murdoch presented to the Royal Society a paper entitled "Account of the Application of Gas from Coal to Economical Purposes" in which he described his successful application of coal-gas to light the extensive establishment of Messrs. Phillips and Lea. For this paper he was awarded Count Rumford's gold medal. [11] Murdoch's statements threw great light on the comparative advantage of gas and candles, and contained much useful information on the expenses of production and management.

Although the history is uncertain, David Melville has been credited [12] [13] [14] [15] with the first house and street lighting in the United States, in either 1805 or 1806 in Newport, Rhode Island. The first well-recorded public street lighting with gas was demonstrated in Pall Mall, London, on January 28, 1807, by Winsor. [16] In 1812, Parliament granted a charter to the London and Westminster Gas Light and Coke Company, and the first gas company in the world came into being. Less than two years later, on December 31, 1813, Westminster Bridge was lit by gas. [17]

As artificial lighting became more common, the desire grew for it to be readily available to the public: partly because towns became much safer places after gas lamps were installed in the streets, reducing crime rates.[ citation needed ] In 1809, accordingly, the first application was made to Parliament to incorporate a company in order to accelerate the process, but the bill failed to pass. In 1810, however, the application was renewed by the same parties, and though some opposition was encountered and considerable expense incurred, the bill passed, but not without great alterations; and the London and Westminster Chartered Gas-Light and Coke Company was established.[ is this the same co. which was given a charter in 1812? ] By 1816, Samuel Clegg obtained the patent for his horizontal rotative retort, his apparatus for purifying coal-gas with cream of lime [ clarification needed ], and for his rotative gas meter and self-acting governor.

Among the economic impacts of gas lighting was much longer work hours in factories. This was particularly important in Great Britain during the winter months when nights are significantly longer. Factories could even work continuously over 24 hours, resulting in increased production. Following successful commercialization, gas lighting spread to other countries.

In England, the first place outside London to have gas lighting was Preston, Lancashire, in 1816; this was due to the Preston Gaslight Company run by revolutionary Joseph Dunn, who found the most improved way[ clarification needed ] of brighter gas lighting. The parish church there was the first religious building to be lit by gas lighting. [18]

In America, Seth Bemis lit his factory with gas illumination from 1812 to 1813. The use of gas lights in Rembrandt Peale's Museum in Baltimore in 1816 was a great success. Baltimore was the first American city with gas street lights; Peale's Gas Light Company of Baltimore on February 7, 1817 lit its first street lamp at Market and Lemon Streets (currently Baltimore and Holliday Streets). The first private residence in the US illuminated by gas has been variously identified as that of David Melville (c. 1806), as described above, or of William Henry, a coppersmith, at 200 Lombard Street, Philadelphia, Pennsylvania, in 1816.

In 1817, at the three stations of the Chartered Gas Company, 25 chaldrons (24 m3) of coal were carbonized daily, producing 300,000 cubic feet (8,500 m3) of gas. This supplied gas lamps equal to 75,000 Argand lamps each yielding the light of six candles. At the City Gas Works, in Dorset Street, Blackfriars, three chaldrons of coal were carbonized each day, providing the gas equivalent of 9,000 Argand lamps. So 28 chaldrons of coal were carbonized daily, and 84,000 lights supplied by those two companies only.

At this period the principal difficulty in gas manufacture was purification. Mr. D. Wilson, of Dublin, patented a method for purifying coal-gas by means of the chemical action of ammoniacal gas.[ clarification needed ] Another plan was devised by Reuben Phillips, of Exeter, who patented the purification of coal-gas by the use of dry lime. G. Holworthy, in 1818, patented a method of purifying it by passing the gas, in a highly condensed state, through iron retorts heated to a dark red.

In 1820, Swedish inventor Johan Patrik Ljungström had developed a gas lighting with copper apparatuses and chandeliers of ink, brass and crystal, reportedly one of the first such public installations of gas lightning in the region, enhanced as a triumphal arch for the city gate for a royal visit of Charles XIV John of Sweden in 1820. [19]

By 1823, numerous towns and cities throughout Britain were lit by gas. Gas light cost up to 75% less than oil lamps or candles, which helped to accelerate its development and deployment. By 1859, gas lighting was to be found all over Britain and about a thousand gas works had sprung up to meet the demand for the new fuel. The brighter lighting which gas provided allowed people to read more easily and for longer. This helped to stimulate literacy and learning, speeding up the second Industrial Revolution.

Oil-gas appeared in the field as a rival of coal-gas. In 1815, John Taylor patented an apparatus for the decomposition of "oil" and other animal substances. Public attention was attracted to "oil-gas" by the display of the patent apparatus at Apothecary's Hall, by Taylor & Martineau.

In 1891 the gas mantle was invented by the Austrian chemist Carl Auer von Welsbach. This eliminated the need for special illuminating gas (a synthetic mixture of hydrogen and hydrocarbon gases produced by destructive distillation of bituminous coal or peat) to get bright shining flames. Acetylene was also used from about 1898 for gas lighting on a smaller scale. [20]

Illuminating gas was used for gas lighting, as it produces a much brighter light than natural gas or water gas. Illuminating gas was much less toxic than other forms of coal-gas, but less could be produced from a given quantity of coal. The experiments with distilling coal were described by John Clayton in 1684. George Dixon's pilot plant exploded in 1760, setting back the production of illuminating gas a few years. The first commercial application was in a Manchester cotton mill in 1806. In 1901, studies of the defoliant effect of leaking gas pipes led to the discovery that ethylene is a plant hormone.

Throughout the 19th century and into the first decades of the 20th, the gas was manufactured by the gasification of coal. Later in the 19th century, natural gas began to replace coal-gas, first in the US, and then in other parts of the world. In the United Kingdom, coal-gas was used until the early 1970s.

Russia

The history of the Russian gas industry began with retired Lieutenant Pyotr Sobolevsky (1782–1841), who improved Philippe le Bon's design for a "thermolamp" and presented it to Emperor Alexander I in 1811; in January 1812, Sobolevsky was instructed to draw up a plan for gas street-lighting for St. Petersburg. The French invasion of Russia delayed implementation, but St. Petersburg's Governor General Mikhail Miloradovich, who had seen the gas lighting of Vienna, Paris and other European cities, initiated experimental work on gas lighting for the capital, using British apparatus for obtaining gas from pit coal, and by the autumn of 1819, Russia's first gas street light was lit on one of the streets on Aptekarsky Island. [21]

In February 1835, the Company for Gas Lighting St. Petersburg was founded; towards the end of that year, a factory for the production of lighting gas was constructed near the Obvodny Canal, using pit coal brought in by ship from Cardiff; and 204 gas lamps were ceremonially lit in St. Petersburg on September 27, 1839.

Over the next 10 years, their numbers almost quadrupled, to reach 800. By the middle of the 19th century, the central streets and buildings of the capital were illuminated: the Palace Square, Bolshaya and Malaya Morskaya streets, Nevsky and Tsarskoselsky Avenues, Passage Arcade, Noblemen's Assembly, the Technical Institute and Peter and Paul Fortress. [22]

Theatrical use

In the 19th century, gas stage lighting went from a crude experiment to the most popular way of lighting theatrical stages. In 1804, Frederick Albert Winsor first demonstrated the way to use gas to light the stage in London at the Lyceum Theatre. Although the demonstration and all the lead research were being done in London, "in 1816 at the Chestnut Street Theatre in Philadelphia was the earliest gas lit theatre in world". [23] In 1817 the Lyceum, Drury Lane, and Covent Garden theatres were all lit by gas. Gas was brought into the building by "miles of rubber tubing from outlets in the floor called 'water joints'" which "carried the gas to border-lights and wing lights". But before it was distributed, the gas came through a central distribution point called a "gas table", [24] which varied the brightness by regulating the gas supply, and the gas table, which allowed control of separate parts of the stage. Thus it became the first stage 'switchboard'. [25]

By the 1850s, gas lighting in theatres had spread practically all over the United States and Europe. Some of the largest installations of gas lighting were in large auditoriums, like the Theatre de Chatelet, built in 1862. [26] In 1875, the new Paris Opera was constructed. "Its lighting system contained more than twenty-eight miles [45 km] of gas piping, and its gas table had no fewer than eighty-eight stopcocks, which controlled nine hundred and sixty gas jets." [27] The theatre that used the most gas lighting was Astley's Equestrian Amphitheatre in London. According to the Illustrated London News, "Everywhere white and gold meets the eye, and about 200,000 gas jets add to the glittering effect of the auditorium … such a blaze of light and splendour has scarcely ever been witnessed, even in dreams." [26]

Theatres switched to gas lighting because it was more economical than using candles and also required less labor to operate. With gas lighting, theatres would no longer need to have people tending to candles during a performance, or having to light each candle individually. "It was easier to light a row of gas jets than a greater quantity of candles high in the air." [25] Theatres also no longer needed to worry about wax dripping on the actors during a show.

Gas lighting also had an effect on the actors. As the stage was brighter, they could now use less make-up and their motions did not have to be as exaggerated. Half-lit stages had become fully lit stages. Production companies were so impressed with the new technology that one said, "This light is perfect for the stage. One can obtain gradation of brightness that is really magical." [25]

The best result was the improved respect from the audience. There was no more shouting or riots. The light pushed the actors more up stage behind the proscenium, helping the audience concentrate more on the action that was taking place on stage rather than what was going on in the house. Management had more authority on what went on during the show because they could see. [28] Gaslight was the leading cause of behavior change in theaters. They were no longer places for mingling and orange selling, but places of respected entertainment.

Types of lighting instruments

There were six types of burners, but four burners were really experimented with.[ clarification needed ]

Several different instruments were used to light the stage in the 19th century fell; these included footlights, border lights, groundrows, lengths, bunch lights, conical reflector floods, and limelight spots. These mechanisms sat directly on the stage, blinding the eyes of the audience.

Gas lighting did have some disadvantages. "Several hundred theatres are said to have burned down in America and Europe between 1800 and the introduction of electricity in the late 1800s. The increased heat was objectionable, and the border lights and wing lights had to be lighted by a long stick with a flaming wad of cotton at the end. For many years, an attendant or gas boy moved along the long row of jets, lighting them individually while gas was escaping from the whole row. Both actors and audiences complained of the escaping gas, and explosions sometimes resulted from its accumulation." [24]

These problems with gas lighting led to the rapid adoption of electric lighting. By 1881, the Savoy Theatre in London was using incandescent lighting. [31] While electric lighting was introduced to theatre stages, the gas mantle was developed in 1885 for gas-lit theatres. "This was a beehive-shaped mesh of knitted thread impregnated with lime that, in miniature, converted the naked gas flame into in effect, a lime-light." [32] Electric lighting slowly took over in theatres. In the 20th century, it enabled better and safer theater productions, with no smell, relatively very little heat, and more freedom for designers.

In the early 20th century, most cities in North America and Europe had gaslit streets. However, around 1880 gas lighting for streets began giving way to high voltage (3000–6000 volt) direct current and alternating current arc lighting systems. This time period also saw the development of the first electric power utility designed for indoor use. The new system by inventor Thomas Edison was designed to function similar to gas lighting. For reasons of safety and simplicity it used direct current (DC) at a relatively low 110 volts to light incandescent light bulbs. Voltage in wires steadily declines as distance increases, and at this low voltage power plants needed to be within about 1 mile (1.6 km) of the lamps. This voltage drop problem made DC distribution relatively expensive and gas lighting retained widespread usage [33] with new buildings sometimes constructed with dual systems of gas piping and electrical wiring connected to each room, to diversify the power sources for lighting.

The development of new alternating current power transmission systems in the 1880s and 90s by companies such as Ganz and AEG in Europe and Westinghouse Electric and Thomson-Houston in the US solved the voltage and distance problem by using high transmission line voltages, and transformers to drop the voltage for distribution for indoor lighting. Alternating current technology overcame many of the limitations of direct current, enabling the rapid growth of reliable, low-cost electrical power networks which finally spelled the end of widespread usage of gas lighting. [33]

In some cities, gas lighting is preserved or restored as a vintage nostalgic feature to support historic atmosphere of their historic centres.

In the 20th century, most cities with gas streetlights replaced them with new electric streetlights. For example, Baltimore, the first US city to install gas streetlights, removed nearly all of them. [34] A sole, token gas lamp is located at N. Holliday Street and E. Baltimore Street as a monument to the first gas lamp in America, erected at that location.

However, gas lighting of streets has not disappeared completely from some cities, and the few municipalities that retained gas lighting now find that it provides a pleasing nostalgic effect. Gas lighting is also seeing a resurgence in the luxury home market for those in search of historical authenticity.

The largest gas lighting network in the world is that of Berlin. With about 37,000 lamps (2014), [35] it holds more than half of all working gas street lamps in the world. In central London around 1500 gas lamps still operate, [16] lighting the Royal Parks, the exterior of Buckingham Palace and almost the entire Covent Garden area. The Park Estate in Nottingham retains much of its original character, including the original gas lighting network.

In the United States, more than 2800 gas lights in Boston operate in the historic districts of Beacon Hill, Back Bay, Bay Village, Charlestown, and parts of other neighborhoods. In Cincinnati, Ohio, more than 1100 gas lights operate in areas that have been named historic districts. Gas lights also operate in parts of the famed French Quarter and outside historic homes throughout the city in New Orleans.

South Orange, New Jersey, has adopted the gaslight as the symbol of the town, and uses them on nearly all streets. Several other towns in New Jersey also retain gas lighting: Glen Ridge, Palmyra, Riverton, and some parts of Orange, Cape May and Cherry Hill. The village of Riverside, Illinois, still uses its original gas street lights that are an original feature of the Frederick Law Olmsted planned community. Manhattan Beach, California, has a gas lamp section in which all the sidewalks are lit by public gas lamps. Disneyland has authentic 19th century gas lamps from Baltimore along the "Main Street, U.S.A." section of the theme park.

Prague had about 10,000 gas streetlamps in the 1940s. The last historic gas candelabras become electrified in 1985. [36] However, in 2002–2014, streetlamps along the Royal Route and some other streets in the centre were rebuilt to use gas (using replicas of the historic poles and lanterns), several historic candelabras (Hradčanské náměstí, Loretánská street, Dražického náměstí etc.) were also converted back to gas lamps, and five new gas lamps were installed in the Michle Gasworks as a promotion. [37] In 2018, there were 417 points (about 650 lanterns) of street gas lighting in Prague. [38] [39] During Advent and Christmas, lanterns on the Charles Bridge are managed manually by a lamplighter in historic uniform. [40]

Many gas utility companies will still quote a fixed periodic rate for a customer-maintained gas lamp, and some homeowners still use such devices. However, the high cost of natural gas lighting [41] at least partly explains why a large number of older gas lamps have been converted to electricity. Solar-rechargeable battery-powered gas light controllers can be easily retrofitted into existing gas lamps to keep the lights off during daylight hours and cut energy consumption and green-house gas carbon emissions by 50%.

Modern indoor usage

The use of natural gas (methane) for indoor lighting is nearly extinct. Besides producing a lot of heat, the combustion of methane tends to release significant amounts of carbon monoxide, a colorless and odorless gas which is more readily absorbed by the blood than oxygen, and can be deadly. Historically, the use of lamps of all types was of shorter duration than we are accustomed to with electric lights, and in the far more draughty buildings, it was of less concern and danger. There are no suppliers of new mantle gas lamps set up for use with natural gas; however, some old homes still have fixtures installed, and some period restorations have salvaged fixtures installed, more for decoration than use.

New fixtures are still made and available for propane (sometimes called "bottle(d) gas"), a product of oil refining, which under most circumstances burns more completely to carbon dioxide and water vapor. In some locations where public utility electricity or kerosene are not readily accessible or desirable, propane gas mantle lamps are still used, although the increased availability of alternative energy sources, such as solar panels and small scale wind generators, combined with increasing efficiency of lighting products, such as compact fluorescent lamps and LEDs are also in use. For occasional use in remote cabins and cottages, propane mantle lamps may still be more economical and less labor-intensive than an alternative energy system.

Other uses

Perforated tubes bent into the shape of letters were used to form gas lit advertising signs, prior to the introduction of neon lights, as early as 1857 in Grand Rapids, Michigan. [42] Gas lighting is still in common use for camping lights. Small portable gas lamps, connected to a portable gas cylinder, are a common item on camping trips. Mantle lamps powered by vaporized petrol, such as the Coleman lantern, are also available.

Stage lighting

Stage lighting is the craft of lighting as it applies to the production of theater, dance, opera, and other performance arts. Several different types of stage lighting instruments are used in this discipline. In addition to basic lighting, modern stage lighting can also include special effects, such as lasers and fog machines. People who work on stage lighting are commonly referred to as lighting technicians or lighting designers.

Timeline of lighting technology

Artificial lighting technology began to be developed tens of thousands of years ago, and continues to be refined in the present day.

Kerosene lamp

A kerosene lamp is a type of lighting device that uses kerosene as a fuel. Invented by the Polish-Armenian pharmacist Ignacy Łukasiewicz in Lviv in 1853, kerosene lamps have a wick or mantle as light source, protected by a glass chimney or globe; lamps may be used on a table, or hand-held lanterns may be used for portable lighting. Like oil lamps, they are useful for lighting without electricity, such as in regions without rural electrification, in electrified areas during power outages, at campsites, and on boats. There are three types of kerosene lamp: flat-wick, central-draught, and mantle lamp. Kerosene lanterns meant for portable use have a flat wick and are made in dead-flame, hot-blast, and cold-blast variants.

Lantern Portable lighting device

A lantern is a portable source of lighting, typically featuring a protective enclosure for the light source—usually a candle or a wick in oil—to make it easier to carry and hang up, and make it more reliable outdoors or in drafty interiors.

Stagecraft technical aspect of theatrical, film, and video production

Stagecraft is the 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.

Coal gas is a flammable gaseous fuel made from coal and supplied to the user via a piped distribution system. It is produced when coal is heated strongly in the absence of air. Town gas is a more general term referring to manufactured gaseous fuels produced for sale to consumers and municipalities.

Street light Raised source of light beside a road or path

A street light, light pole, lamppost, street lamp, light standard or lamp standard is a raised source of light on the edge of a road or path. When urban electric power distribution became ubiquitous in developed countries in the 20th century, lights for urban streets followed, or sometimes led.

Coal gasification is the process of producing syngas–a mixture consisting primarily of carbon monoxide (CO), hydrogen (H2), carbon dioxide (CO2), natural gas (CH4), and water vapour (H2O)–from coal and water, air and/or oxygen.

Carbide lamp

Carbide lamps, or acetylene gas lamps, are simple lamps that produce and burn acetylene (C2H2) which is created by the reaction of calcium carbide (CaC2) with water (H2O).

History of lighthouses

The history of lighthouses refers to the development of the use of towers, buildings, or other types of structure, as an aid to navigation for maritime pilots at sea or on inland waterways.

A safety lamp is any of several types of lamp that provides illumination in coal mines and is designed to operate in air that may contain coal dust or gases both of which are potentially flammable or explosive. Until the development of effective electric lamps in the early 1900s miners used flame lamps to provide illumination. Open flame lamps could ignite flammable gases which collected in mines, causing explosions and so safety lamps were developed to enclose the flame and prevent it from igniting the surrounding atmosphere. Flame safety lamps have been replaced in mining with sealed explosion-proof electric lights.

Lamplighter person employed to light and maintain street lights

A lamplighter is a person employed to light and maintain candle or, later, gas street lights. Very few exist today as most gas street lighting has long been replaced by electric lamps.

Lampshade

A lampshade is a fixture that covers the lightbulb on a lamp to diffuse the light it emits. Lampshades can be made out of a wide variety of materials like paper, glass, fabric or stone. Usually conical or cylindrical in shape, lampshades can be found on floor, desk, tabletop, or suspended lamps. The term can also apply to the glass hung under many designs of ceiling lamp. Beyond its practical purpose, significant emphasis is also usually given to decorative and aesthetic features. A lamp shade also serves to "shade" human eyes from the direct glare of the light bulbs used to illuminate the lamp. Some lamp shades are also lined with a hard-backed opaque lining, often white or gold, to reflect as much light as possible through the top and bottom of the shade while blocking light from emitting through the walls of the shade itself. In other cases, the shade material is deliberately decorative so that upon illumination it may emphasize a display of color and light emitting through the shade surface itself.

Light fixture device that provides light

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.

Ceremonial use of lights

The ceremonial use of lights is found in the practice of many religions. Candles are extremely common and other forms of light, whether fire or other, are also used.

Argand lamp

The Argand lamp, a kind of oil lamp, was invented and patented in 1780 by Aimé Argand. Its output is 6 to 10 candelas, brighter than that of earlier lamps. Its more complete combustion of the candle wick and oil than in other lamps required much less frequent trimming of the wick.

Altar candle

Altar candles are candles set on or near altars for religious ceremonies. Various denominations have regulations or traditions regarding the number and type of candles used, and when they are lit or extinguished during the services.

Luminous flame

A luminous flame is a burning flame which is brightly visible. Much of its output is in the form of visible light, as well as heat or light in the non-visible wavelengths.

A Wells light was a large paraffin-fuelled (kerosene) blowlamp used for engineering work, particularly for illumination, in Victorian times. At a time before widespread electrical lighting, they were the most common form of high-powered portable illumination used for construction work, particularly railways, civil engineering, shipyards and ironworks.
