    What is the difference between RGBW and RGB?


    In color lighting applications, RGB and RGBW LEDs are the most common choices. Although they can achieve rich color changes, 

    they are essentially different in structure and effect:


    RGB (red, green, blue) LED

    It is composed of three chips, Red, Green, and Blue, which are mixed to produce various colors by controlling the ratio.

    Advantages:


    Can generate a variety of colors


    Flexible control


    Suitable for stage lights, billboards and other colorful needs


    Disadvantages:


    White light is a mixture of three colors, and the color temperature is unstable and impure


    Low color rendering index, not suitable for scenes with high requirements for "real restoration"


    RGBW (red, green, blue, and white) LED

    Adding an independent white light chip (W) on the basis of RGB can provide truly pure white light.


    Advantages:


    Provide high-quality white light output with stable color temperature


    More suitable for scenarios that require "multi-color + white light" (such as architectural projection, smart home)


    Energy saving: Use W lamp beads instead of RGB mixed light to output white light, with lower power consumption


    RGBW = RGB creativity + white light practicality! Want to take into account both atmosphere and daily lighting? RGBW is a more comprehensive choice.
