    Light bulb colors and temperature can drastically affect how we view a space. This is similar to the subtle change you might notice in a paint color from the morning to the afternoon—it all has ...

  3. Color temperature - Wikipedia

    en.wikipedia.org/wiki/Color_temperature

    An incandescent lamp's light is thermal radiation, and the bulb approximates an ideal black-body radiator, so its color temperature is essentially the temperature of the filament. Thus a relatively low temperature emits a dull red and a high temperature emits the almost white of the traditional incandescent light bulb.

  4. Correlated color temperature - Wikipedia

    en.wikipedia.org/wiki/Correlated_color_temperature

    A black body is characterized by its temperature and emits light of a specific hue, which is referred to as color temperature. [ 3 ] [ 4 ] [ 5 ] In practice, light sources that approximate Planckian radiators, such as certain fluorescent or high-intensity discharge lamps, are assessed based on their CCT, which is the temperature of a Planckian ...

    [citation needed] Yellow light was obtained by dint of yellow glass for the headlight bulb or lens, a yellow coating on a colourless bulb, lens, or reflector, or a yellow filter between the bulb and the lens. [65] Filtration losses reduced the emitted light intensity by about 18 percent, which might have contributed to the reduced glare. [66]

  7. High-intensity discharge lamp - Wikipedia

    en.wikipedia.org/wiki/High-intensity_discharge_lamp

    The Kelvin color temperature scale ranges from 1000K (amber) to 3000K (yellow) to 5500K (white) to 8000K (blue) to 12000K (purple). HID Lamp Color Temperature Range. 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]

  8. Luminous efficacy - Wikipedia

    en.wikipedia.org/wiki/Luminous_efficacy

    Sources that depend on thermal emission from a solid filament, such as incandescent light bulbs, tend to have low overall efficacy because, as explained by Donald L. Klipstein, "An ideal thermal radiator produces visible light most efficiently at temperatures around 6300 °C (6600 K or 11,500 °F). Even at this high temperature, a lot of the ...
