Once the LED strips are physically installed, it's time to connect them to the power supply. Connect the positive and negative terminals of the LED strip (or controller, if using one) to the corresponding terminals on the LED power supply/driver. Ensure all connections are secure, either by using wire connectors, terminal blocks, or soldering. If using a controller for dimming or color changes, ensure it's connected correctly between the power supply and the LED strip. Route the low-voltage wiring discreetly, perhaps along the wall trim or inside a conduit, to the LED power supply, which should be plugged into a standard wall outlet. If the power supply is not easily accessible, consider installing it inside a junction box or behind a piece of furniture.
