  2. High-intensity discharge lamp - Wikipedia

    en.wikipedia.org/wiki/High-intensity_discharge_lamp

    Exposure to HID lamps operating with faulty or absent UV-blocking filters causes injury to humans and animals, such as sunburn and arc eye. Many HID lamps are designed to quickly extinguish if their outer UV-shielding glass envelope is broken. Beginning in the early 1990s, HID lamps have seen applications in automotive headlamps. Xenon, or high ...

  3. Gas-discharge lamp - Wikipedia

    en.wikipedia.org/wiki/Gas-discharge_lamp

    High-pressure lamps have a discharge that takes place in gas under slightly less to greater than atmospheric pressure. For example, a high pressure sodium lamp has an arc tube under 100 to 200 torr pressure, about 14% to 28% of atmospheric pressure; some automotive HID headlamps have up to 50 bar or fifty times atmospheric pressure.

    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 ...

    en.wikipedia.org/wiki/Construction_Field_Computing

    Construction field computing is the use of handheld devices that augment the construction superintendent's ability to manage the operations on a construction site. These information appliances (IA) must be portable devices which can be carried or worn by the user, and have computational and connectivity capacity to perform the tasks of communication management.
