A high-intensity discharge lamp type that uses mercury as the primary light-producing element. Mercury vapor lamps produce light with a CCT from 3000 to 7000 K. Mercury vapor lamps with clear outer bulbs have CRI values from 15 to 25, whereas phosphor-coated lamps have CRI values from 40 to 55. Mercury vapor lamps are less efficacious than other HID lamp types, typically producing only 30 to 65 LPW, but they have longer lamp lives and lower initial costs than other HID lamp types.
a gas discharge lamp which uses mercury in an excited state to produce light
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.
A high intensity discharge (HID) lamp in which the major portion of the light is produced by radiation from atomized mercury particles. Mercury vapor provides reasonably good color rendering of earth tones but is the least efficient of HID lamp types.
The earliest form of High-Intensity Discharge (HID) lamp; can be used either indoors or outdoors.
Short arc mercury vapor lamps make a good light source for laser illuminated holograms. Images are brighter and more evenly lit than with a laser. But cost and maintenance still often make this type of hologram impractical for public disaplay.
A type of HID lamp in which the major portion of the light is produced by radiation from mercury vapor. Emits a blue-green cast of light. Available in clear and phosphor coated lamps.
is a popular type of artificial light source which emits a blue-white light. Used extensive for commercial lighting.
An HID lamp that produces light by radiation from mercury vapor. Mercury lamps have a distinct blue-green color and are a popular moonlight source for very large trees in commercial environments. Some folks think this type of lamp makes everything look ghoulish.
Artificial light source produced by passing current through mercury vapor in a tube.
A high-intensity discharge lamp that uses mercury as the primary light-producing element. Includes clear, phosphor coated, and self-ballasted lamps.
