   en.wikipedia.org/wiki/Searchlight

   A searchlight (or spotlight) is an apparatus that combines an extremely bright source (traditionally a carbon arc lamp) with a mirrored parabolic reflector to project a powerful beam of light of approximately parallel rays in a particular direction. It is usually constructed so that it can be swiveled about.

3. Polilight - Wikipedia

   en.wikipedia.org/wiki/Polilight

   The PL500 ('500' refers to the power in watts of the xenon arc lamp) has eleven monochromatic bands, a ‘blank’ position that provides high intensity white light in the range from 380 to 650 nm and an optional infra-red output suitable for document examination.

4. 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 ...

5. Light characteristic - Wikipedia

   en.wikipedia.org/wiki/Light_characteristic

   A Morse code light is light in which appearances of light of two clearly different durations (dots and dashes) are grouped to represent a character or characters in the Morse Code. For example, "Mo(A)" is a light in which in each period light is shown for a short period (dot) followed by a long period (dash), the Morse Code for "A".

6. Hydrargyrum quartz iodide - Wikipedia

   en.wikipedia.org/wiki/Hydrargyrum_quartz_iodide

   The lamp is powered by an electrical ballast, which regulates the current flow through the arc in the arctube, and an ignitor, to make the high voltage pulse that is necessary to start the arc in the arctube. Like all HID lamps, HQI lamps operate under high pressure and temperature, and require special light fixtures for safe use.

7. Xenon arc lamp - Wikipedia

   15 kW xenon short-arc lamp used in IMAX projectors High-speed, slow-motion video of a xenon flashtube recorded at a speed of 44,025 frames per second.. A xenon arc lamp is a highly specialized type of gas discharge lamp, an electric light that produces light by passing electricity through ionized xenon gas at high pressure.
