How to Wire a DC LED Strip

Using LEDs, or light-emitting diodes, are an efficient way to provide accent lighting because they consume only a small amount of electricity. LED lights require a special power supply to convert the 120-volt alternating current to a much lower 12-volt direct current. This power supply is a small rectangular black box with several terminals on its side for connecting LED lights. These lights are available in red, orange, amber, yellow, green, blue and white colours. The material that the semi conductor is made of determines the colour. Wiring your DC LED strip is easy once you know where to connect the wires.
