• The Kelvin Scale:
  
  Color temperature is a kind of visible light that has important applications in lighting. 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.
  
  
  
  Different color temperature light of source also offer different light color, it will bring you a different feeling:
  
  • 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.
  
  
• Type of Fitting:
  
  These pictures below display the most common fittings. If you know your fitting, you can easily find the right LED bulbs to match.
