A mercury-vapor lamp is a gas discharge lamp that uses an electric arc through vaporized mercury to produce light. The arc discharge is generally confined to a small fused quartz arc tube mounted within a larger borosilicate glass bulb.This lamp is containing an inner quartz arc tube and outer borosilicate glass envelope. The quartz tube is a..
