CCT is measured in Kelvin (K), which is similar to degrees in Celsius. Color temperature (Correlated Color Temperature, or CCT, in lighting tech jargon) is essentially a gauge of how yellow or blue the color of light emitted from a light bulb appears. It’s measured in the Kelvin unit and is most commonly found between 2200 Kelvin degrees and 6500 Kelvin degrees.

Different temperatures on the Kelvin scale represent different colors. For example, light at 2000K-3500K looks more orange/yellow and is called ultra warm or warm white, and as temperature increases in Kelvins, color changes to more of a “paper white” known as natural or neutral white (between 3500K and 5100K) and finally into a bluish-white known as cool white (5100K-20000K).

The Slim Recessed Lighting Kits are the recessed lights of the future. Not only is each fixture designed specifically for small spaces where height clearance is limited such as beams or duct work, you can change the color temperature with a flick of a switch. The integrated color changing switch is located on the cable so you can choose between 2700, 3000, 3500, 4000 or 5000K temperature to best suit your needs. 2700K Warm White, 3000K Soft White, 3500K Neutral White, 4000K Bright White and 5000K-day Light.
