   Tungsten filament lamps were first marketed by the Hungarian company Tungsram in 1904. ... The 1902 tantalum filament light bulb was the first one to have a metal ...

3. Edison light bulb - Wikipedia

   en.wikipedia.org/wiki/Edison_light_bulb

   [1] [2] These carbon filament bulbs, the first electric light bulbs, became available commercially that same year. [3] In 1904 a tungsten filament was invented by Austro-Hungarians Alexander Just and Franjo Hanaman , [ 4 ] and was more efficient and longer-lasting than the carbonized bamboo filament used previously. [ 5 ]

4. Centennial Light - Wikipedia

   en.wikipedia.org/wiki/Centennial_Light

   Its continuous operation has largely eliminated the stresses associated with turning a light bulb on and off, the act of which causes the temperature of the bulb to increase and decrease. The bulb was made by hand, using a carbon filament (of greater thickness and strength than the tungsten filaments used in most modern lightbulbs) along with ...

5. Daniel McFarlan Moore - Wikipedia

   en.wikipedia.org/wiki/Daniel_McFarlan_Moore

   The modest success of the Moore tubes was among the drivers for developing better filaments for standard incandescent light bulbs. Tungsten filament bulbs were a sufficient enough improvement over carbon filaments that the Moore tubes "gradually disappeared from the market, leaving only short carbon-dioxide tubes in use for color matching, in ...

6. Alexander Just - Wikipedia

   en.wikipedia.org/wiki/Alexander_Just

   In 1904 with Austro-Hungarian Franjo Hanaman he was the first to develop and patent an incandescent light bulb with a tungsten filament, made by extruding a paste of tungsten powder and a carbonaceous binder to produce a fine thread, then removing the carbon by heating in an atmosphere of hydrogen and water vapors. [3]

7. Tungsram - Wikipedia

   en.wikipedia.org/wiki/Tungsram

   The name "Tungsram" is a portmanteau of tungsten (/ ˈ t ʌ ŋ s t ən / TUNG-stən) and wolfram (/ ˈ w ʊ l f r əm / WUUL-frəm), the two common names of the metal used for making light bulb filaments. Before becoming nationalized by the Communist government in 1945, the company was the world's third largest manufacturer of light bulbs and ...
