Technically CCT stands for "Correlated Colour Temperature" but in our world we like to refer to it as Colour Changing Temperature. The ability to tune the colour of your lights from warm white to cool white and any place between allows you to not worry about how the light will reflect when in use. This video will show you up close how you can get changing colour temperatures from one LED chip. For kitchens, this light is one of our most popular products. CCT Puck lights are also available for use in any cabinets with glass doors. The colour temperature changes will sync with your under cabinet lights.
