2. High-intensity discharge lamp - Wikipedia

   en.wikipedia.org/wiki/High-intensity_discharge_lamp

   High-intensity discharge lamps are a type of arc lamp. Brand new high-intensity discharge lamps make more visible light per unit of electric power consumed than fluorescent and incandescent lamps, since a greater proportion of their radiation is visible light in contrast to infrared. However, the lumen output of HID lighting can deteriorate by ...

3. Flashlight - Wikipedia

   en.wikipedia.org/wiki/Flashlight

   A less common type of flashlight uses a high-intensity discharge lamp (HID lamp) as the light source. An HID gas discharge lamp uses a mixture of metal halide salts and noble gas as a filler. HID lamps produce more light than a traditional incandescent flashlight using the same amount of electricity, though not as much as high power LEDs.

4. Xenon arc lamp - Wikipedia

   en.wikipedia.org/wiki/Xenon_arc_lamp

   However, even in a high pressure lamp there are some very strong emission lines in the near infrared, roughly in the region from 850 to 900 nm. This spectral region can contain about 10% of the total emitted light. [citation needed] Light intensity ranges from 20,000 to 500,000 cd/cm 2. An example is the "XBO lamp", which is an OSRAM trade name ...

5. Metal-halide lamp - Wikipedia

   en.wikipedia.org/wiki/Metal-halide_lamp

   A metal-halide lamp is an electrical lamp that produces light by an electric arc through a gaseous mixture of vaporized mercury and metal halides [1] [2] (compounds of metals with bromine or iodine). It is a type of high-intensity discharge (HID) gas discharge lamp. [1]

6. Flashtube - Wikipedia

   en.wikipedia.org/wiki/Flashtube

   As the duration of the flash that is emitted by a xenon flashtube can be accurately controlled, and due to the high intensity of the light, xenon flashtubes are commonly used as photographic strobe lights. Xenon flashtubes are also used in very high-speed or "stop-motion" photography, which was pioneered by Harold Edgerton in the 1930s.

7. Gas-discharge lamp - Wikipedia

   en.wikipedia.org/wiki/Gas-discharge_lamp

   A high-intensity discharge (HID) lamp is a type of electrical 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. Compared to other lamp types, relatively high arc power exists for the arc length.
