Step 6 · Connect to Power Source

At the end of the series of LED strips, you will have a main wire leading to the power source. Connect this wire to the low-voltage power supply (e.g., a 12V or 24V DC adapter). Ensure the polarity is correct: the positive wire from the LED strip must connect to the positive terminal of the power supply, and the negative wire to the negative terminal. Use appropriate connectors or solder the connection, and insulate it well with heat-shrink tubing or electrical tape. Ensure the power supply is rated for the total wattage of all your LED strips and is placed in an accessible yet unobtrusive location, such as near an existing outlet or a designated junction box.
