Flex Spectrum Exterior is an IP68, RGBW flexible LED circuit strip, in a 16.4' spool with wired digital communication network. It is designed to give you a wide range of color to choose from in applications where both color and dedicated white are required. By mixing blue with 3000K inside the quad-color diode, you get a white range from 3000K-7000K, while maintaining an 80 CRI.
