A light source containing an arc (see above). Also called a discharge lamp, or an arc discharge lamp.
Arc Length(HID)
In High Intensity Discharge lamps this is the distance between the electrode tips, which represents the physical length of the electrical discharge. .
Fixture Requirements(LF)
Describes fixture requirements for HID lamps.
O = Open or Enclosed Fixtures
E = Enclosed Fixtures Only
S = Lamps operated in a vertical position (Base Up or Down) ±15o, can be used in an open fixture. Lamps burned in any other orientation must be used in "enclosed fixtures only." See additional details in the e-Catalog Help Menu under the HID category.
Floodlight(LF)
A luminaire used to light a scene or object to a level much brighter than its surroundings. Usually floodlights can be aimed at the object or area of interest.
High Intensity Discharge(HID)Lamp(HID)
A general term for mercury, metal halide (GE ConstantColor? CMH?, Multi-Vapor?, MXR or Arcstream?) and high-pressure sodium (GE Lucalox?) lamps. HID lamps contain compact arc tubes which enclose mercury and various gases with other chemicals and operate at relatively high pressures and temperatures.
High-Pressure Sodium(HPS)Lamp(HID)
HPS lamps are high intensity discharge light sources that product light by an electrical discharge though sodium vapor operating at relatively high pressures and temperatures. GE markets these lamps under the trade name of Lucalox?.
Hot Restart Time(HID)
Time it takes for a High Intensity Discharge lamp to reach 90% of light output after going from on to off to on.
Mercury Lamp(HID)
A high-intensity discharge light source operating at a relatively high pressure (about 1 atmosphere) and temperature in which most of the light is produced by radiation from excited mercury vapor. Phosphor coatings on some lamp types add additional light and improve color rendering.
Metal Halide Lamp(HID)
A high intensity discharge light source in which the light is produced by the radiation from mercury, plus halides of metals such as sodium, scandium, indium and dysprosium. Some lamp types may also utilize phosphor coatings.
Mogul Base(HID)
A screw base used on larger lamps, e.g. many HID lamps.
Pulse Start(HID)
An HID ballast with a high voltage ignitor to start the lamp.
Arc Lamp(HID)
