High Intensity Discharge Lamp Types

High intensity discharge lamps hid lamps are a type of electrical gas discharge lamp which produces light by means of an electric arc between tungsten electrodes housed inside a translucent or transparent fused quartz or fused alumina arc tube.

High intensity discharge lamp types. However the mercury vapor lamp is the least efficient of hid type lamps and poses a greater environmental risk than other types such as high pressure sodium hps lamps and metal halide mh lamps. Most farms have at least one high intensity discharge lamp hid lighting up the yard at night. High intensity discharge lamp ed28 bulb shape ex39 base type 5000k 50 000 h 115 w note. Types of high intensity discharge lamps mercury vapor lamps shortwave uv a result of the decay of mercury atom electrons from an excited to a stable state is readily transmitted through the inner quartz tube but is virtually blocked by the outer glass envelope during normal operation.
