While installing the selected led strip power supply, we will connect the red and black wires of the LED strip light to the corresponding terminals or leads of the power supply. Therefore, you need to pay attention to the positive poles and negative poles of the light strip. They must correspond to the positive and negative poles of the led lamp driver output, normally sign + or +V for red line; - or -V or COM for black line.

3.The light strip and the led light bulb power supply have pig tail lead at the same time. You can use the terminal to connect the leads between power supply and the light strip. You can also use wire-end ferrules to connect, then put on the heat shrink tubing to provide insulation. Terminal on connectors and wire-end ferrules are easy and professional way for electrician because of that do not need soldering.
