HID (High Intensity Discharge ) High Pressure Mercury Vapour (HPMV) Lamps
The high pressure mercury vapour lamp was one of the first HID lamp types to appear on the market in 1930s. The outer bulb stabilizes and maintains the necessary high temperature around the arc tube and also absorbs the potentially hazardous UV radiation coming from the arc. Nitrogen gas within the outer bulb protects the metal parts from oxidation
luminous efficacy of around 50–65 lumens per watt,
