It is a type of lighting solution that can be used in a variety of applications, such as accent lighting, task lighting, and decorative lighting. There is a variation of the LED strip that follows the same work principle but instead of the LED connection being set up using a flexible circuit, it is done using wires. This variation is called an LED string. I use LED strings to decorate my Christmas tree. Figure 9.1 shows a photo of an LED strip on the left and an LED string on the right.

LED strips come in a range of colors and color temperatures, and they are available in various lengths and densities. They are typically...
