Neon is the gas which glows in diverse colors depending on which substance it is mixed with in fluorescent lamp tube.
A fluorescent lamp tube is filled with a gas including low-pressure mercury vapor and xenon, argon, neon, or krypton.
The pressure inside the lamp is about 0.3% of atmospheric pressure.
