La Compagnie des Lampes ("The Lamp Company") was a name used by several French companies all in the area of electrical products particularly lighting.
The original Compagnie des Lampes was set up at Ivry-sur-Seine in 1888. The plant was subsequently attached to the CGE (Compagnie Générale d'Electricité) on its acquisition in 1898. The plant is classified as a historical monument.
In 1915, the plant was the second to start manufacturing TM triodes ("Télégraphie Militaire") in France, under their Métal brand (the first was E.C.&A. Grammont (Lyon) under their Radio Fotos brand). [1] [2] [3] [4] [5] [6] Later they made tubes for domestic AC transformer heating such as the BW604 and BW1010 under their Métal-Secteur brand.
Founded in 1911 by Paul Blavier, La Compagnie des Lampes was a light bulb factory workshop, located in Saint-Pierre-Montlimart, near Cholet. The company changed its name in 1918 to become Manufacture de lampes à incandescence, la Française. It was associated with the Thomson group in the 1950s.
In 1921 CFTH (Compagnie Française Thomson-Houston) and CGE (Compagnie Générale d'Electricité) jointly created a new Compagnie des Lampes. It later became a major player in the field of lighting in France, notably through its brand MAZDA. [7]
Between 1924 and 1939, it was part of the Phoebus cartel, an oligopoly that dominated the market for light bulbs while putting in place an agreement on the principle of planned obsolescence for their products.
Besides light bulbs (and like British Ediswan), CdL (1921) also made vacuum tubes under the Mazda brand, for example 6H8G (1947), [8] 3T100A1 (1949), [9] E1 (1950); [10] since 1953 as LAMPE MAZDA: 2G21 (1953), [11] 927 (1954), [12] EL183 (1959), [13] EF816 (1962). [14]
Many of their tubes were also available from Compagnie Industrielle Française des Tubes Electroniques (CIFTE) [15] under their Mazda-Belvu [16] brand (originating from Societé Radio Belvu, [17] which sold Grammont's Fotos tubes). [18]
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.
The Phoebus cartel was an international cartel that controlled the manufacture and sale of incandescent light bulbs in much of Europe and North America between 1925–1939. The cartel took over market territories and lowered the useful life of such bulbs. Corporations based in Europe and the United States, including Osram, General Electric, Associated Electrical Industries, and Philips, incorporated the cartel on January 15, 1925 in Geneva, as Phœbus S.A. Compagnie Industrielle pour le Développement de l'Éclairage. Although the group had intended the cartel to last for thirty years, it ceased operations in 1939 with the outbreak of World War II. Following its dissolution, light bulbs continued to be sold at the 1,000-hour life standardized by the cartel.
A monoscope was a special form of video camera tube which displayed a single still video image. The image was built into the tube, hence the name. The tube resembled a small cathode ray tube (CRT). Monoscopes were used beginning in the 1950s to generate TV test patterns and station logos. This type of test card generation system was technologically obsolete by the 1980s.
Mazda was a trademarked name registered by General Electric (GE) in 1909 for incandescent light bulbs. The name was used from 1909 to 1945 in the United States by GE and Westinghouse. Mazda brand light bulbs were made for decades after 1945 outside the US. The company chose the name due to its association with Ahura Mazda, the transcendental and universal God of Zoroastrianism whose name means light of wisdom in the Avestan language.
Veolia Environnement S.A., branded as Veolia, is a French transnational company with activities in three main service and utility areas traditionally managed by public authorities – water management, waste management and energy services. It previously also managed transport services through its subsidiary Veolia Transport until January 2019. In 2022, Veolia employed 220,000 employees in 58 countries. Its revenue in that year was recorded at €42,885 million. It is quoted on Euronext Paris. It is headquartered in Aubervilliers.
In Europe, the principal method of numbering vacuum tubes was the nomenclature used by the Philips company and its subsidiaries Mullard in the UK, Valvo(de, it) in Germany, Radiotechnique (Miniwatt-Dario brand) in France, and Amperex in the United States, from 1934 on. Adhering manufacturers include AEG (de), CdL (1921, French Mazda brand), CIFTE (fr, Mazda-Belvu brand), EdiSwan (British Mazda brand), Lorenz (de), MBLE(fr, nl), RCA (us), RFT(de, sv) (de), Siemens (de), Telefunken (de), Tesla (cz), Toshiba (ja), Tungsram (hu), and Unitra. This system allocated meaningful codes to tubes based on their function and became the starting point for the Pro Electron naming scheme for active devices.
Alcatel–Lucent S.A. was a multinational telecommunications equipment company, headquartered in Boulogne-Billancourt, France. It was formed in 2006 by the merger of France-based Alcatel and U.S.-based Lucent, the latter being a successor of AT&T's Western Electric and a holding company of Bell Labs.
SA Ateliers de Constructions Electriques de Charleroi (ACEC) was a Belgian manufacturer of electrical generation, transmission, transport, lighting and industrial equipment, with origins dating to the late 19th century as a successor to the Société Électricité et Hydraulique founded by Julien Dulait.

The Compagnie générale française des transports et entreprises, commonly known by the initialism CGFTE, was a company which managed public transportation networks in several French cities, including Bordeaux (TBC), Nancy, Rouen (TCAR) and Chambéry (Stac). It was formed in 1953 from Compagnie Générale Française de Tramways (CGFT), which was created in 1875.

The Conférence des Grandes Écoles (CGE), French for "Conference of Grandes Écoles", is a French national institution, created in 1973. It mainly acts as an association of Grandes Écoles, providing representation, research and accreditation.

The Edison and Swan Electric Light Company Limited was a manufacturer of incandescent lamp bulbs and other electrical goods. It was formed in 1883 with the name Edison & Swan United Electric Light Company with the merger of the Swan United Electric Company and the Edison Electric Light Company.
Radiotechnique (RT) was a French electronics company that made radio transmitting and receiving vacuum tubes, and later more advanced components such as integrated circuits and solar panels. At first it was a subsidiary of the French Compagnie générale de la télégraphie sans fil (CSF). Later it became a subsidiary of Philips of the Netherlands. The company expanded after World War II, moving into television and electronics, including photovoltaics and printed circuits, and in 1979 had about 15,000 employees. Later it lost market share, went through various restructurings, was sold in 1998 and went bankrupt in 2002.
The TM was a triode vacuum tube for amplification and demodulation of radio signals, manufactured in France from November 1915 to around 1935. The TM, developed for the French Army, became the standard small-signal radio tube of the Allies of World War I, and the first truly mass-produced vacuum tube. Wartime production in France is estimated at no less than 1.1 million units. Copies and derivatives of the TM were mass-produced in the United Kingdom as Type R, in the Netherlands as Type E, in the United States and in Soviet Russia as P-5 and П7.
The Empain group was a loose grouping of companies founded by Édouard Empain (1852–1929) of Belgium and controlled by the Empain family. From 1881 until merging with Schneider & Cie in 1969, the companies engaged in a broad range of activities including tramways, railways, electricity generation, construction and mining. The main areas of activity were Belgium and France, but the group also pursued opportunities in Russia, Egypt, China and elsewhere, and played a large role in the development of the eastern Belgian Congo.
The 455-line standard, also known as 450-line, was a French black-and-white analog television broadcasting norm employed between 1937 and 1939. It was later replaced by the 441-line format, which remained in use until 1956.
