Mercury vapor lamps were the first high intensity discharge lamps to be commercially available for a wide variety of lighting applications. Because mercury lamps are so prevalent in current outdoor lighting, and still safe when properly installed in a serviceable fixture, the need for these products will continue for many more years. LED bulbs use significantly less energy and need to be replaced less often than other HID bulb types. Once the lamp has warmed up and the mercury is fully vaporised, the discharge operates in unsaturated mercury vapour at a pressure varying from 18 bar for the smallest types, to 2 bar for the largest. Because mercury lamps are so prevalent in current outdoor lighting, and still safe when properly installed in a serviceable fixture, the need for these products will continue for many more years.
