2. High-intensity discharge lamp - Wikipedia

   en.wikipedia.org/wiki/High-intensity_discharge_lamp

   As the HID lights use less than half the power of an equivalent tungsten-halogen light, a significantly smaller and lighter-weight power supply can be used. HID lamps have also become common on many aircraft as replacements for traditional landing and taxi lights. [citation needed] HID lamps are also used in lamps for underwater diving.

3. Metal-halide lamp - Wikipedia

   en.wikipedia.org/wiki/Metal-halide_lamp

   It is a type of high-intensity discharge (HID) gas discharge lamp. [1] Developed in the 1960s, they are similar to mercury vapor lamps, [1] but contain additional metal halide compounds in the quartz arc tube, which improve the efficiency and color rendition of the light. The most common metal halide compound used is sodium iodide. Once the arc ...

   Halogen headlights were developed in Europe in 1960. High-intensity discharge (HID) headlights were produced starting in 1991. In 1993, the first LED tail lights were installed on mass-production automobiles, with LED headlights subsequently being introduced in the 2000s as more powerful LEDs became available. [5]

   As of 2010, LED headlamps such as those available on the Toyota Prius were providing output between halogen and HID headlamps, [129] with system power consumption slightly lower than other headlamps, longer lifespans, and more flexible design possibilities.

6. Halogen lamp - Wikipedia

   en.wikipedia.org/wiki/Halogen_lamp

   Halogen lamps are sometimes used for inspection lights and microscope stage illuminators. Halogen lamps were used for early flat-screen LCD backlighting, but other types of lamps such as CCFL and now LED are used. Halogen lamps are used as the heating element in the fuser of many types of laser printers. The long tubular lamp heats the fuser ...

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.
