What is Color Temperature?

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 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.
To simplify the selection of LED light bulb color temperatures we use the following definitions for various color temperatures:

  • Warm White    – 3000K typical incandescent light bulb
  • Neutral White – 4100K typical retail space using white fluorescent light
  • Daylight             –  5000K used for high color definition – typical afternoon sun light
  • Cool White       –  5700K used in many industrial and commercial applications like hospitals
