How to Install Low Voltage Landscape Lighting

Landscape lighting transforms a dark backyard into a usable evening space while providing essential safety along paths and stairs. Unlike high-voltage house wiring, low-voltage systems use a transformer to step down power to 12 volts, making the installation process far safer and easier for the home user to handle without needing an electrician. Success in this project lies in the planning phase and the quality of your connections. If you bury your wires at the correct depth and use reliable, waterproof connectors, your system will run for years without maintenance. Done well, your yard will look professionally lit, highlighting key features while remaining subtle and elegant.

1. Map the lighting vision. Place your light fixtures around the patio or path without burying anything yet. Connect them to the transformer location to ensure your cable run reaches all points comfortably.
2. Secure the power source. Mount the transformer to a wall near an exterior GFCI outlet, keeping it at least 12 inches above ground level. Ensure the outlet is covered by an in-use weatherproof box cover.
3. Route the cable run. Unspool your low-voltage direct-burial cable along the path of your fixtures. Keep the cable tight against hardscaping or tucked just behind garden edging.
4. Plant and connect fixtures. Drive the stakes into the ground and secure the light heads. Connect each fixture to the main cable using the provided wire-piercing connectors until they click or screw tight.
5. Hide the wiring underground. Use a spade to cut a narrow slit in the soil about 4 to 6 inches deep. Press the cable into the slit and stomp the ground closed to hide the wire.
6. Power up and perfect angles. Plug the transformer into the outlet and set your timer or photo-sensor. Walk the property to ensure every light is working and adjust the angle of the light heads.
