In February 1892, Tesla gave a lecture to the Institution of Electrical Engineers, in which he described the carbon button lamp in detail. He also described several variants of the lamp, one of which uses a ruby drop in place of the carbon button. Tesla went on to develop it as a near commercial lighting product. [1]
The company was formed in a partnership between Tesla, Robert Lane and Benjamin Vail with Tesla given the task of designing an arc lighting system, a fast growing segment of the new electric light industry used mostly for outdoor lighting. Tesla designed an arc lamp with automatic adjustment and a fail-switch as well as

Tesla used an incandescent-type lamp ball with a single internal conductive element and excited the element with high voltage currents from a Tesla coil, thus creating the brush discharge emanation. He gained patent protection on a particular form of the lamp in which a light-giving small body or button of refractory material is supported by a ...
