Tantris lightbulb

Throughout the 20th century, the incandescent lightbulb was the most widespread type of lighting, with a multitude of uses. It consisted of the following components: a base with contacts to the power source, a glass bulb, and a filament that emitted light as electricity flowed through it. It is impossible to name one single inventor of the lightbulb, as many researchers were independently researching the emission of light by a heated conductor connected to an electricity source. In 1854, the author of one of the most advanced designs that had the characteristics of today’s lightbulbs was Heinrich Goebel – an engineer and mechanic of German descent from New York. Over its long history, the lightbulb underwent many improvements. This lightbulb was made in the Małopolska Fabryka Żarówek SA in Lviv, which had been operating from 1928. Manufacturer: “Tantris” Małopolska Fabryka Żarówek SA, around 1930 Inv. No.: MIM1221/IV-34 Model prepared on the basis of photogrammetric measurements. Licence: CC BY-NC-SA
