   en.wikipedia.org/wiki/Ceramic_metal-halide_lamp

   Streetlamp with a ceramic metal halide bulb Ceramic metal halide bulb with G12 socket. A ceramic metal-halide lamp (CMH), also generically known as a ceramic discharge metal-halide (CDM) lamp, [1] is a type of metal-halide lamp that is 10–20% more efficient than the traditional quartz metal halide [2] and produces a superior color rendition (80-96 CRI).

   Like other gas-discharge lamps such as the very-similar mercury-vapor lamps, metal-halide lamps produce light by ionizing a mixture of gases in an electric arc.In a metal-halide lamp, the compact arc tube contains a mixture of argon or xenon, mercury, and a variety of metal halides, such as sodium iodide and scandium iodide.

   Auctions were held annually in 21 years between 2000 and 2022, with no auctions in 2020 and 2021 due to the COVID-19 pandemic. In total, auctions on eBay for lunch with Buffett raised $53.2 million for the Glide Foundation, with winning bids ranging from $2 million to as high as $19 million for the final auction in 2022.

   With HMI bulbs, color temperature varies significantly with lamp age. A new bulb generally will output at a color temperature close to 15,000 K during its first few hours. As the bulb ages, the color temperature reaches its nominal value of around 5600 K or 6000 K. With age, the arc length becomes larger as more of the electrodes burn away.

6. Bi-pin lamp base - Wikipedia

   A metal halide lamp with a bipin cap. A bipin or bi-pin (sometimes referred to as two-pin, bipin cap or bipin socket) is a type of lamp fitting.They are included in the IEC standard "IEC 60061 Lamp caps and holders together with gauges for the control of interchangeability and safety".

7. High-intensity discharge lamp - Wikipedia

   en.wikipedia.org/wiki/High-intensity_discharge_lamp

   HID lamps produce different colors of light primarily through the use of various metal additives in the lamp's arc tube and the physics of the gas discharge process. [11] Metal Additives: HID lamps contain an arc tube filled with a mixture of gases, including a noble gas (like xenon). These metal additives are crucial for producing different ...
