Based at the site where 1571-1579 Irving Street now stands, on Irving Street between Coach and Elizabeth, [1] Rahway, New Jersey, Tesla Electric Light and Manufacturing Company was started in December 1884 after the inventor Nikola Tesla left Thomas Edison's employment following a disagreement over payment. [2]
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 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 and 1939. . The cartel took over market territories and lowered the useful life of such bulbs, which is commonly cited as an example of planned obsolescen
Inventor Nikola Tesla is quoted as saying "[Edison's] method was inefficient in the extreme, for an immense ground had to be covered to get anything at all unless blind chance intervened and, at first, I was almost a sorry witness of his doings, knowing that just a little theory and calculation would have saved him 90 percent of the labour ...
The plasma lamp was invented by Nikola Tesla, during his experimentation with high-frequency currents in an evacuated glass tube for the purpose of studying high voltage phenomena. [2] Tesla called his invention an "inert gas discharge tube". [3] The modern plasma lamp design was developed by James Falk and MIT student Bill Parker. [1] [4]

Tesla invented the Tesla coil during efforts to develop a "wireless" lighting system, with gas discharge light bulbs that would glow in an oscillating electric field from a high voltage, high frequency power source. [11] [8] For a high frequency source Tesla powered a Ruhmkorff coil (induction coil) with his high frequency alternator.
However, using solid-state chips to generate RF is currently an order of magnitude more expensive than using a magnetron and so only appropriate for high-value lighting niches. It has recently been shown by Dipolar [1] of Sweden to be possible to extend the life of magnetrons to over 40,000 hours, [ 1 ] making low-cost plasma lamps possible.
