Immediately following neon's discovery, neon tubes were used as scientific instruments and novelties. [16] However, the scarcity of purified neon gas precluded its prompt application for electrical gas-discharge lighting along the lines of Moore tubes , which used more common nitrogen or carbon dioxide as the working gas, and enjoyed some ...
A General Electric NE-34 glow lamp, manufactured circa 1930. Neon was discovered in 1898 by William Ramsay and Morris Travers.The characteristic, brilliant red color that is emitted by gaseous neon when excited electrically was noted immediately; Travers later wrote, "the blaze of crimson light from the tube told its own story and was a sight to dwell upon and never forget."

[15] Following neon's discovery, neon tubes were used as scientific instruments and novelties. [16] A sign created by Perley G. Nutting and displaying the word "neon" may have been shown at the Louisiana Purchase Exposition of 1904, although this claim has been disputed; [ 17 ] in any event, the scarcity of neon would have precluded the ...
A very common Penning mixture of about 98–99.5% of neon with 0.5–2% argon is used in some neon lamps, especially those rated for 120 volts. The mixture is easier to ionize than either neon or argon alone, and lowers the breakdown voltage at which the tube becomes conductive and starts producing light.
1910 Georges Claude demonstrates neon lighting at the Paris Motor Show. 1912 Charles P. Steinmetz invents the metal-halide lamp. [13] 1913 Irving Langmuir discovers that inert gas could double the luminous efficacy of incandescent lightbulbs. 1917 Burnie Lee Benbow patents the coiled coil filament. 1920 Arthur Compton invents the sodium-vapor ...
Electroluminescent nightlights use little electrical power. Early electrical nightlights used small incandescent lamps or small neon lamps to provide light, and were much safer than small candles using an open flame. The neon versions consumed very little energy and had a long life, but had a tendency to flicker on and off (reminiscent of a ...
Neon tubes may partially burn out, and a conservator may identify the burned out portion of a neon artwork through use of a neon light tester, also known as a test light or voltage tester. This electronic test device is used to determine whether an electric current is running through the equipment being tested.
