Answer 1Noble gases aren't used in fluorescent lights. The gas in a fluorescent light is usually Mercury vapor. Answer 2
  • It is neon, argon, or mercury vapor
  • Gas-based lighting took advantage of the luminescent qualities of neon, an inert gas that had been discovered in 1898 by isolation from the atmosphere. Neon glowed a brilliant red when used in Geissler tubes. By 1910, Georges Claude, a Frenchman who had developed a technology and a successful business for air liquefaction, was obtaining enough neon as a byproduct to support a neon lighting industry.
  • While neon lighting was used around 1930 in France for general illumination, it was no more energy-efficient than conventional incandescent lighting.
  • Neon tube lighting includes the use of argon and mercury vapor as alternate gases
