2. Color temperature - Wikipedia

   en.wikipedia.org/wiki/Color_temperature

   The color temperature scale describes only the color of light emitted by a light source, which may actually be at a different (and often much lower) temperature. [ 1 ] [ 2 ] Color temperature has applications in lighting , [ 3 ] photography , [ 4 ] videography , [ 5 ] publishing , [ 6 ] manufacturing , [ 7 ] astrophysics , [ 8 ] and other fields.

   The last two digits indicate the color temperature of the lamp in kelvins (K). For example, if the last two digits on a lamp say 41, that lamp's color temperature will be 4100 K, which is a common tri-phosphor cool white fluorescent lamp. BL is used for ultraviolet lamps commonly used in bug zappers.

4. 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]

5. Compact fluorescent lamp - Wikipedia

   en.wikipedia.org/wiki/Compact_fluorescent_lamp

   The color temperature of a light source is the temperature of a black body that has the same chromaticity (i.e. color) as the light source. A notional temperature, the correlated color temperature, the temperature of a black body that emits light of a hue that to human color perception most closely matches the light from the lamp, is assigned ...

7. Hydrargyrum medium-arc iodide lamp - Wikipedia

   en.wikipedia.org/wiki/Hydrargyrum_medium-arc...

   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.

8. Lighting - Wikipedia

   en.wikipedia.org/wiki/Lighting

   The color temperature of a white light source is the temperature in kelvins of a theoretical black body emitter that most closely matches the spectral characteristics (spectral power distribution) of the lamp. An incandescent bulb has a color temperature around 2800 to 3000 kelvins; daylight is around 6400 kelvins.
