context_page_description: La Compagnie des Lampes was a name used by several French companies all in the area of electrical products particularly lighting.
context_section_description: 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.
  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), 3T100A1 (1949), E1 (1950); since 1953 as LAMPE MAZDA: 2G21 (1953), 927 (1954), EL183 (1959), EF816 (1962).
  Many of their tubes were also available from Compagnie Industrielle Française des Tubes Electroniques (CIFTE) under their Mazda-Belvu brand (originating from Societé Radio Belvu, which sold Grammont's Fotos tubes).
