Q - What is color temperature, or Corrected Color Temperature?

A - The output hue of white LED lights is often described in terms of "Color Temperature" or "Corrected Color Temperature", expressed in units of Kelvin. In short, CCT approximates the surface temperature of an "ideal" heated light-emitting body- for example the tungsten filament of an incandescent light bulb. Typical color temperatures for white LED's range from about 10,000 K, which is distinctly blue, to a natural daylight white at 5000 K, down to the yellower color of a traditional incandescent light at about 2700.
