Sk68 12 and WS28 12 are both built-in IC, but they are two different models, and they are generally 5050 brackets. There are many kinds of luminous colors. Can it change color automatically? Compared with ordinary 5050RGB, the color is more vivid and bright, generally divided into three colors: red, green and blue, and the red brightness is 400-. Green brightness: 800- 1000MCD, blue brightness: 400-500MCD, voltage: 2.0-2.2/3.0-3.2V, power: 0.2W, which is a constant current and constant voltage 5050 patch light source.
