   The introduction of the metal vapor lamp, including various metals within the discharge tube, was a later advance. The heat of the gas discharge vaporizes some of the metal and the discharge is then produced almost exclusively by the metal vapor. The usual metals are sodium and mercury owing to their visible spectrum emission.

   The heat generated by the arc and electrodes then ionizes the mercury and metal halides into a plasma, which produces an increasingly brighter white light as the temperature and pressure increases to operating conditions. The arc-tube operates at anywhere from 5–50 atm or more [8] (70–700 psi or 500–5000 kPa) and 1000–3000 °C. [9]
