2. Ceramic metal-halide lamp - Wikipedia

   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).

3. Chemical coloring of metals - Wikipedia

   en.wikipedia.org/wiki/Chemical_coloring_of_metals

   Chemical coloring of metals is the process of changing the color of metal surfaces with different chemical solutions. The chemical coloring of metals can be split into three types: electroplating – coating the metal surface with another metal using electrolysis. patination – chemically reacting the metal surface to form a colored oxide or ...

4. Metal-halide lamp - Wikipedia

   en.wikipedia.org/wiki/Metal-halide_lamp

   A metal-halide lamp is an electrical lamp that produces light by an electric arc through a gaseous mixture of vaporized mercury and metal halides [1] [2] (compounds of metals with bromine or iodine). It is a type of high-intensity discharge (HID) gas discharge lamp . [ 1 ]

   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. Neon lighting - Wikipedia

   en.wikipedia.org/wiki/Neon_lighting

   Neon lights are a type of cold cathode gas-discharge light. A neon tube is a sealed glass tube with a metal electrode at each end, filled with one of a number of gases at low pressure. A high potential of several thousand volts applied to the electrodes ionizes the gas in the tube, causing it to emit colored light. The color of the light ...

7. Metallic color - Wikipedia

   en.wikipedia.org/wiki/Metallic_color

   A metallic color is a color that appears to be that of a polished metal. The visual sensation usually associated with metals is its metallic shine . This cannot be reproduced by a simple solid color , because the shiny effect is due to the material's brightness varying with the surface angle to the light source.
