Color temperature can be used to gauge the hue of white that a light source produces. It is measured in degrees Kelvin (K) and can be used to determine the warmth (yellowish hue) or coolness (bluish hue) of a white light.
In many public areas, a warmer white is chosen to promote relaxation, where a cooler white may be chosen in buildings where concentration is important, such as offices.
Below is a scale that will graphically display the range of the color temperature scale.
Some common colors associated with the color temperature scale are:
|Match / Candle Flame:||1500 - 1850K|
|Soft White Incandescent:||2550K|
|Warm White LEDs:||2900-3200K|
|Pure White LEDs:||4100-4300K|
|Natural White LEDs:||4200-4500K|
|Daylight White LEDs:||5000-5500K|
|Cool White LEDs:||5500-6000K|
|LED or CRT Sceen:||6500-9500K|
|Clear Blue Sky:||15000 - 27000K|
