How to Choose the Right LED Lighting
Product Color Temperature
Applicability: All LED Products
LED lighting offers many benefits and features that were difficult, if not impossible to offer with other lighting technologies.
Many of the obvious benefits, such as substantial operating energy and cost reductions, longer life, and lower overall heat
generation are generally well known. Another feature that allows for dramatic appearance and productivity benefits now
and in the future, involves the color temperature of the light produced by LEDs.
Lighting Color Temperature Measurement Beginnings
"White light" is commonly described by its color temperature. Measuring the hue of “white” light started in the late 1800s,
when the British physicist William Kelvin heated a block of carbon. The block of carbon changed color as it heated up, going
from a dim red, through various shades of yellow, all the way up to a bright bluish white at its highest temperature. The
measurement scale for color temperatures, which was named after Kelvin as a result of his work, was based Centigrade
degrees. However, since the Kelvin scale starts at “absolute zero”, which is ‐273°C, you can get the equivalent Centigrade
temperature (compared to the visible colors of a heated black body) by subtracting 273 from the Kelvin color temperature.
Color Temperature Scale Application
The term used
in general
illumination is correlated color
temperature (CCT). CCT relates
to the color of light produced
by a light source, and uses the
Kelvin
temperature
measurement scale (SI unit of
absolute
temperature).
It
describes the relative color
appearance of a white light
source, indicating whether it
appears more
yellow/gold
(“warm”) or more blue (“cool”),
in terms of the
