Neon gas produces a distinctive reddish-orange glow when an electric current is forced through a tube containing the gas at a low pressure. These vacuum electric-discharge tubes are used extensively in the familiar neon light of advertising displays. The term neon light is often incorrectly applied to discharge tubes filled with gases other than neon that produce a colored glow (see Neon Lamp). Other uses of neon include in television tubes, gas lasers, and high-voltage indicators. Liquid neon is used as a cryogenic refrigerant (see Cryogenics). It has over 40 times more refrigerating capacity per unit volume than liquid helium.
