The color temperature of a light source is the temperature of an ideal black-body radiator that radiates light of comparable hue to that of the light source. Color Temperature is a measurement in Degrees Kelvin that indicates the hue of a specific type of light source， the symbol of unit is K.<br><br><br><br>Different color temperature light of source also offer different light color， it will bring you a different feeling:<br>Higher color temperatures (5000K or more) are "cold"， color is green to blue.Moderate temperature (3000-5000K) are "cool"， color is white.Lower color temperatures (2700-3000K) are "warm"， color is yellow to red.<br>Type of Fitting: <br><br>These pictures below display the most common fittings.
