What is color temperature, and how does it indicate
to
the color of the light output from a lamp? |
| Color temperature (or
correlated color temperature, CCT) is a
number indicating the degree of yellowness
or blueness of a white light source. Measured
in Kelvins, CCT represents the temperature
an incandescent object (like a filament)
must reach to mimic the color of the lamp.
Yellowish-white (warm) sources, like incandescent
lamps, have lower color temperatures in
the 2700K-3000K range; white and bluish-white
(cool) sources, such as cool white (4100K)
and natural daylight (6000K), have higher
color temperatures. The higher the color
temperature the whiter, or bluer, the light
will be. |
