Hardwiring LED light strips is a more permanent and secure way of installing them, especially for installations where you want to avoid using plugs or rely on power supplies with specific outputs. Here’s a step-by-step guide on how to hardwire LED light strips safely and effectively.
Before you start, make sure you have the following tools and materials:
led strip lights (12V or 24V)
Power supply (matching the voltage and wattage requirements of the LED strip)
Soldering iron (if necessary)
Electrical wire (appropriate gauge for the LED strip)
Wire cutters and strippers
Screwdriver
Heat shrink tubing or electrical tape for insulation
Wire connectors (optional)
Voltage tester (optional but recommended)
Decide where you want to install your LED strips and how long they need to be. Measure the space and calculate how much LED strip you’ll need. Mark out where the power supply will be connected and whether it will be plugged directly into the electrical system or through a switch.
LED strips come in different voltage options, usually 12V or 24V. Make sure that the power supply matches the voltage of your LED strips, and it must be able to handle the total wattage of the strips.
Calculate the total wattage: Add up the wattage of each LED strip segment (usually listed per meter) and multiply it by the total length you plan to use.
Power Supply Wattage: Make sure the power supply has a wattage rating that exceeds the total wattage of the connected LED strips by about 20% for safe operation.
If your LED strip needs to be cut to fit a specific length:
Cut at the designated points: Most LED strips have cut points, often marked with a scissor icon. These points are where the circuit can be safely cut without damaging the strip.
To hardwire the LED strip to your power supply, you will likely need to solder the power supply wires to the LED strip's positive and negative terminals.
Prepare the wire: Cut the electrical wire to the desired length and strip the ends to expose the copper.
Solder the wires: Use a soldering iron to attach the positive (+) and negative (-) wires from the power supply to the corresponding pads on the LED strip.
Use heat shrink tubing: Once the wires are soldered, slide heat shrink tubing over the exposed soldered joints to protect them. Alternatively, use electrical tape to insulate the connections and prevent short circuits.
Now that the LED strips are soldered to the wires:
Connect the wires to the power supply: Attach the other end of the wires to the output terminals of the power supply. For a 12V LED strip, connect the positive wire to the positive terminal and the negative wire to the negative terminal on the power supply.
Secure the connections: Use screw terminals, wire connectors, or soldering to ensure the wires are securely attached to the power supply.
Once your wiring is complete, mount the LED strips where you want them to go:
Use adhesive backing: Most LED strips come with adhesive backing, but make sure the surface is clean before applying. For more permanent installations, you can use mounting clips or brackets.
Secure the wires: Use zip ties or clips to secure the wires neatly along the wall or surface to avoid visible or tangled cables.
After installation, test the setup:
Power on: Plug in the power supply, or turn on the switch if it’s wired to a switch.
Check the lighting: Ensure the LED strips turn on properly and the connections are working without flickering or dim spots.
Double-check wiring: Make sure all connections are properly insulated to prevent short circuits or power surges.
Check for overheating: After turning on the lights, monitor the setup for the first few minutes to ensure there’s no overheating or issues with the power supply.
Fuse Protection: Consider adding a fuse between the power supply and LED strips to protect from overloads.
