How to Install Low-Voltage Outdoor Path Lighting

Path lighting transforms your home's exterior from a dark silhouette into a welcoming, safe environment while providing essential visibility for walkways. The secret to a professional result isn't the cost of the fixtures, but the care you take in layout and the hidden routing of your power cables. Executing this project well means keeping your connections waterproof and ensuring the transformer is protected from the elements. By using a low-voltage system, you eliminate the need to bury deep electrical conduits, making this a manageable project that yields high-impact results for your home's curb appeal.

1. Map Your Path First. Place your light fixtures along the path to determine spacing, typically 6 to 8 feet apart to avoid a runway effect. Use small flags or white spray paint to mark where each fixture and the power hub will go.
2. Protect the Power Hub. Install the transformer on an exterior wall near a GFCI-protected outlet, ensuring it is at least 12 inches above ground level. Keep it in a dry, shaded location if possible to prolong the life of the internal components.
3. Run Cable Along Path. Unspool your low-voltage landscape wire along the path, connecting it to the transformer terminals. Ensure the cable reaches every light location with enough slack to allow for adjustments.
4. Clip Lights to Wire. Connect each light fixture to the main cable using the provided specialized quick-connect clips. These clips pierce the cable insulation to make contact with the wire inside without needing to strip it.
5. Test Before Burying. Plug the transformer into the outlet and turn on the system before burying any wires. Walk the path to check that every light is functioning and the light levels are consistent across the entire length.
6. Hide Wires Underground. Use a spade to create a narrow slit in the grass or soil about 3 to 6 inches deep. Press the cable into the slit and step on the turf to close it, hiding the wire from view.
