Description
Neon emission tube. A neon lamp consists of a glass tube containing neon gas at a low pressure and two metal electrodes at either end. When an voltage is applied, the gas becomes ionized and begins to glow as it transmits a current between the electrodes. Pure neon has a red-orange glow. Different colors can be achieved by the addition of impurities such as argon or krypton. Neon lights are more efficient than carbon filament lamps.
