2. Metal-halide lamp - Wikipedia

   en.wikipedia.org/wiki/Metal-halide_lamp

   On fixtures without instant restrike capability, a momentary loss of power can mean no light for several minutes. For safety reasons, some metal-halide fixtures have a backup tungsten-halogen incandescent lamp that operates during cool-down and restrike. Once the metal halide restrikes and warms up, the incandescent safety light is switched off.

   It was widely utilized in roadway and high mast applications around the world replacing 400 watt, 750 watt and 1000 watt metal halide and high pressure sodium systems.

4. Hydrargyrum quartz iodide - Wikipedia

   Hydrargyrum quartz iodide (HQI) is a trademark name of Osram's brand of metal halide lamps [1] made for general floodlighting, arena floodlighting, shop and commercial and industrial lighting. Hydrargyrum is the Latin name for the element mercury. When heated, mercury vapour is created inside the lamp, and deposited when it cools.

   Additionally, various colors are used to identify what type of lamp the fixture uses. A yellow sticker indicates the lamp is a sodium vapor lamp (HPS/LPS). A blue sticker indicates the lamp is mercury vapor (MV). A red sticker indicates the lamp is metal halide (MH). A sticker that is half-red and half-white indicates a pulse start metal halide ...

   The efficiency advantage is near fourfold, with approximately 85–108 lumens per watt of electricity. Unlike regular incandescent halogen lamps where a halide gas is used to regenerate the filament and keep the evaporated tungsten from darkening the glass, the mercury vapour and the metal halides in HMI lamps are what emit the light.

7. High-intensity discharge lamp - Wikipedia

   However, mercury-vapor lamps are falling out of favor and being replaced by sodium-vapor and metal-halide lamps. Metal-halide and ceramic metal-halide lamps can be made to give off neutral white light useful for applications where normal color appearance is critical, such as TV and movie production, indoor or nighttime sports games, automotive ...
