LED lights are also called light-emitting diodes. The power consumption of a single LED light is minimal. From blue to red, LED lights come in many colors. Among various colors, they can be roughly divided into two types: high brightness and low brightness. Since white is a mixed color and has no identifiable wavelength value, it is expressed by its coordinate value on the chromaticity diagram. We customize it into two types: "cool white" and "warm white". There is a problem of color deviation in various colors, especially white, and LED suppliers cannot effectively control it.
