RGW+CCT lighting refers to an advanced lighting system that combines the capabilities of RGB (red, green, blue) lighting with an additional white light channel and CCT (Correlated Color Temperature) adjustment. This system allows for a wide range of colors, including various shades of white light, from warm to cool temperatures. The RGW+CCT lighting controller is a device used to control and adjust the colors and color temperatures of the lighting system. It provides the ability to select and customize the desired color or white light output, enabling users to create dynamic and personalized lighting effects for different settings and moods.
