Can I change the monochromatic light into three-color light?

Of course. According to the relevant data of monochromatic light, monochromatic light can be replaced by trichromatic light. Just find a voltage regulator. Turning down the voltage will reduce the brightness. As for the color separation adjustment, the monochrome voltage can be controlled separately. Monotone light element is a color, and three colors are composed of red, yellow-green, and blue, which is true color. The three-tone light element is RBG reflective powder with three colors. When the driving current of LED is adjusted, the color of LED will change accordingly. With the controller, you can adjust any color, support programming, and use it on LED wall washing lights and LED light bars.
