EagleLight's LED University: Color Temperature & Kelvin Explained
Definition of LED Color Temperature
In this installment EagleLight's LED University explains what "color temperature" means.
LED color temperature measures the color of an LED light bulb. It defines the amount of pure white, yellow, red and blue in a light. Another way to think of the color temperature is how 'warm' or 'cool' is the white LED light bulb.
Color temperature is measured in degrees Kelvin and is a measure of the part of the color spectrum that is found in light.
A simple way to think about this is to compare the light from the sun from sunrise to sunset. At noon the light is bright and white, even more so nearer the equator. At sunrise and sunset the light takes on a more yellow or even red tint. Lower color temperatures will have more yellow, and higher color temperatures will go from yellow, to pure white and eventually to bluish, like you might find on some of the blue tinted headlights on cars.
Examples of Color TemperatureThe following table offers a broader example of the types of color temperature:
EagleLight use of LED Color TemperatureTo simplify the selection of LED light bulb color temperatures EagleLight uses the following definitions for various color temperatures:
For the scientists: The Color Temperature Scale defines the spectral distribution of the light source. It is measures in degrees Kelvin, where Kelvin is equal to the Celsius temperature minus 273 degrees. The Kelvin Color Temperature is the light emitted from a black body energy source at that given temperature. For more information, open pop-up here.
EagleLight names for Color Temperature
White LEDs are available in many levels of Kelvin color temperature. The descriptions used in this site for color temperature typically conform to the following:
Color temperature is an aesthetic choice, so each person will have their own preference for each setting and application. Preference is as individual and varied as there are applications and people. Here is what we have found to be generally true, but in no true for all people.
Older eyes often times see better in cooler color temperatures. Women often prefer warmer colors than men. Task lighting is better if cooler. Cooler whites raise attention. Warmer whites soften the environment and make for a more relaxed space. Warmer whites will hide the true color of objects and add yellow tint.
