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 ...

   I have (twice now) restored appropriately supported, verifiable text regarding the widespread illegality of installing HID light bulbs in car headlamps intended to take halogen filament bulbs, in response to an IP-only editor replacing the supported assertions with technically inaccurate material probably derived from what the IP-only editor thinks she or he understands from a seller of such ...

4. 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 ...

   Similar to fluorescent lights, HMIs present problems with color temperature when used for film or video lighting applications.Unlike incandescent-lighting units, which are blackbody radiators limited to a theoretical maximum of 3680 K (the melting point of tungsten), HMI lamps, like all gas discharge lighting, emit the emission spectral lines of its constituent elements, specifically chosen so ...

6. Sodium-vapor lamp - Wikipedia

   en.wikipedia.org/wiki/Sodium-vapor_lamp

   LPS lamps are similar to fluorescent lamps in that they are a low-intensity light source with a linear lamp shape. They do not exhibit a bright arc as do high-intensity discharge (HID) lamps; they emit a softer luminous glow, resulting in less glare. Unlike HID lamps, during a voltage dip low-pressure sodium lamps return to full brightness rapidly.
