Thorn Lighting Ltd, a subsidiary of the Zumtobel Group, is a global supplier of both outdoor and indoor luminaires and integrated controls.
Thorn was founded when Sir Jules Thorn started The Electric Lamp Service Company Ltd, in 1928, dealing in incandescent filament lamps. In 1936, renamed Thorn Electrical Industries, the company was floated on the London Stock Exchange. Continuous post World War II expansion followed and the organisation seized a variety of lighting, engineering and consumer electronics businesses, merging with EMI in 1979 to create Thorn EMI, which itself demerged in the year 1996. [3]
In 1994, following a leveraged management buy-out, Thorn Lighting Ltd floated on the London Stock Exchange as TLG plc (the Thorn Lighting Group) until it was acquired by Wassall plc four years later. In 2000, Wassall plc was purchased in order to merge TLG with the luminaire business of the Zumtobel Group, an acquisition financed with the assistance of private equity firm KKR who subsequently reduced its position. Thorn is now fully owned by the Zumtobel Group.
The Thorn brand started life as the Electric Lamp Service Company Limited, established by Jules Thorn on 29 March 1928, importing incandescent filament lamps and radio valves from the continent. Faced with increased import duties, [4] introduced to aid British manufacturing, Jules Thorn bought his first lighting factory, the Atlas Lamp Works Ltd in Edmonton, north London in 1932. In 1936 the company went public as Thorn Electrical Industries.
The lamp businesses prospered until 1939 when production was geared to military needs. When war broke out a second lamp site, run by the Vale Royal Electric Lamp Company, was bought in nearby Tottenham in case Edmonton was bombed.
When World War II ended, Jules Thorn continued expansion through investing in new plants, partnerships and acquisitions, including the opening of an incandescent lamp operation in Merthyr Tydfil, [5] [6] South Wales in 1947; a technology transfer with Sylvania Electric Products to mass-produce tubular fluorescent lamps in Enfield, north London and taking over 51% of Ekco-Ensign Electric (Ekco) in 1950, which added a further incandescent lamp factory – in Preston, [7] Lancashire.
In 1951, Thorn took over Smart & Brown (Engineers) Ltd's luminaire factory at Spennymoor, [8] near Durham. In the mid-1950s specialist incandescent lamp factories were opened in Buckie, [9] [10] Scotland and in Wimbledon, London (the Omega Electric Lamp Works Ltd). [11]
Between 1952 and 1964 Thorn established additional overseas connections, including a controlling interest in an Italian lamp manufacturer (SIVI Illuminazione SpA) and plants in Australia, South Africa and New Zealand, followed by agencies in the Middle East and Hong Kong, the latter with Jardine Pacific.
In September 1959 a new London-based headquarters was opened. Thorn House, designed by Sir Basil Spence, was at the time England's tallest office block.[ citation needed ]
In 1964, driven by the need to compete more effectively in world markets, Thorn merged its lighting interests with those of Associated Electrical Industries (AEI) [12] to form British Lighting Industries Ltd, [13] taking a controlling 65% share (the remaining 35% being acquired three years later). AEI Lamp and Lighting brought to the BLI group three significant lighting interests: British Thomson-Houston (BTH) which owned major factories, especially at Melton Road in Rushey Mead, Leicester [14] in the East Midlands of England (producing discharge lamps) and in Hereford, near the Welsh border (making luminaires), and sold lamps under the ‘Mazda’ brand; [15] Metropolitan-Vickers (MV) which drew supplies from the BTH factories, selling them under the 'Metrovick' brand; and the Edison & Swan Electric Light Company (Ediswan), which had recently transferred its factory at Ponders End [16] and ‘Royal Ediswan’ brand over to BTH. Within a year of its formation BLI reorganised - consolidating laboratories, factories, and selling functions - to operate under just three main brands: Atlas, Mazda and Ekco (the remaining 49% interest in Ekco-Ensign being secured in 1966). Once complete, in 1969, the BLI name was changed to Thorn Lighting Ltd and subsequently the Ekco and Atlas brand names were replaced by the Thorn name.
Substantial export growth followed, quickly earning a Queen's Award for Export Achievement, in 1968, and five years later Romford Export Centre opened, stocking over 10,000 items.
By 1976 over 50% of sales were from outside the United Kingdom. 1979 saw Thorn acquire Gebr Kaiser GmbH & Co. Leuchten K.G, a West German manufacturer of lighting fittings, and two years later close the Tottenham lamp factory.
In 1987 the purchase of the Jarnkonst group of Nordic light fitting companies and closure of the Buckie lamp factory signalled a new drive by parent Thorn EMI to trade an export and ‘colonies’ mentality for a multi-cultural, international outlook, one that took account of the forthcoming Single European Act. Gaining critical mass in lighting fixtures – defined as 10% market share in any one county – was identified as a priority.
In 1988 Thorn EMI bought the French group Holophane to gain access to its luminaire subsidiary, Europhane. The Jardine Pacific relationship in Asia was developed into an 18-year joint-venture, and the lighting brands of Sydney based Howard Smith were acquired.
On 14 November 1990, Thorn announced that it had agreed to sell its principal light source interests to GE Lighting of the United States. Under the agreement, GE acquired the lamp plants at Enfield, Leicester [17] and Wimbledon, as well as Thorn's 51% in SIVI Illuminazione in Italy and 100% holding in Gluhlampenfabrik Jahn, a small specialist manufacturer in Germany. Thorn subsequently closed its Merthyr Tydfil lamp factory, consolidated its UK distribution centres and sold its South African business. In 1991, Thorn won Management Today's Business in Europe Award. [18]
Using Hong Kong as a platform, the company entered Macau, Taiwan, Singapore, Malaysia, Thailand, South Korea and Japan, while additional offices and agents were established in Eastern Europe. In 1992, placing staff in Jardine offices throughout mainland China secured more projects [19] (at £35m Hong Kong International Airport became, and remains today, Thorn's largest ever contract) and laid the groundwork for local manufacturing. The Guangzhou fluorescent fittings factory opened in 1996 and Tianjin followed a year later, making road and tunnel luminaires. That same year, an interest in Thorn India was established. European activities centred on the purchase of Jakobsson in Denmark.
On-going consolidation in the late 1990s saw the closure of the Hereford factory and luminaire production transfer from the Kaiser Leuchten factory to other sites.
The new millennium marked a new beginning as the Zumtobel Group invested heavily in Thorn, particularly in technological innovation, and consolidating the former regionally structured production operations of Zumtobel and Thorn into a single worldwide supply chain. It also sought organic growth in clearly defined regions and market sectors.[ citation needed ]
In 2006, the Zumtobel Group sold Thorn's airfield ground lighting activities (Thorn AFL) to the Swedish airport specialist Safegate, [20] and two years later merged two former luminaire production facilities to form a new plant at Wetherill Park, Sydney.
In 2009, Thorn invested in a new factory, laboratory and training and exhibition complex (the Thorn Academy of Light) in Spennymoor. [21] The Distribution Centre at the former site nearby was retained. The plant was named UK Factory of the Year for 2009. [22] This year also saw Thorn and Hess AG of Germany enter into a long-term sales partnership for outdoor lighting products. [23] Initially, activity centred on Germany, where Hess’ subsidiary, Vulkan, marketed Thorn's range, but further agreements were reached in 2011, extending Thorn rights to Hess products in France, East and Southeast Europe, and the UK and Ireland.

An electric light, lamp, or colloquially called light bulb is an electrical device 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. The electrical connection to the socket may be made with a screw-thread base, two metal pins, two metal caps or a bayonet cap.
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.
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 with a vacuum or inert gas 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.
Associated Electrical Industries (AEI) was a British holding company formed in 1928 through the merger of the British Thomson-Houston Company (BTH) and Metropolitan-Vickers electrical engineering companies. In 1967 AEI was acquired by GEC, to create the UK's largest industrial group. A scandal that followed the acquisition is said to have been instrumental in reforming accounting practices in the UK.
British Thomson-Houston (BTH) was a British engineering and heavy industrial company, based at Rugby, Warwickshire, England, and founded as a subsidiary of the General Electric Company (GE) of Schenectady, New York, United States. They were known primarily for their electrical systems and steam turbines.
A sodium-vapor lamp is a gas-discharge lamp that uses sodium in an excited state to produce light at a characteristic wavelength near 589 nm.
A mercury-vapor lamp is a gas-discharge lamp that uses an electric arc through vaporized mercury to produce light. The arc discharge is generally confined to a small fused quartz arc tube mounted within a larger soda lime or borosilicate glass bulb. The outer bulb may be clear or coated with a phosphor; in either case, the outer bulb provides thermal insulation, protection from the ultraviolet radiation the light produces, and a convenient mounting for the fused quartz arc tube.
A compact fluorescent lamp (CFL), also called compact fluorescent light, energy-saving light and compact fluorescent tube, is a fluorescent lamp designed to replace an incandescent light bulb; some types fit into light fixtures designed for incandescent bulbs. The lamps use a tube that is curved or folded to fit into the space of an incandescent bulb, and a compact electronic ballast in the base of the lamp.
The history of street lighting in the United States is closely linked to the urbanization of America. Artificial illumination has stimulated commercial activity at night, and has been tied to the country's economic development, including major innovations in transportation, particularly the growth in automobile use. In the two and a half centuries before LED lighting emerged as the new "gold standard", cities and towns across America relied on oil, coal gas, carbon arc, incandescent, and high-intensity gas discharge lamps for street lighting.
An emergency light is a battery-backed lighting device that switches on automatically when a building experiences a power outage.
The induction lamp, electrodeless lamp, or electrodeless induction lamp is a gas-discharge lamp in which an electric or magnetic field transfers the power required to generate light from outside the lamp envelope to the gas inside. This is in contrast to a typical gas discharge lamp that uses internal electrodes connected to the power supply by conductors that pass through the lamp envelope. Eliminating the internal electrodes provides two advantages:
The Thomson-Houston Electric Company was a manufacturing company which was one of the precursors of the General Electric company.
Thorn Electrical Industries Limited was a British electrical engineering company. It was listed on the London Stock Exchange, but merged with EMI Group to form Thorn EMI in 1979. It was de-merged in 1996 and became a constituent of the FTSE 100 Index, but was acquired by the Japanese Nomura Group only two years later, it is now owned by Terra Firma Capital Partners.
A light fixture, light fitting, or luminaire is an electrical device containing 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.
