Step-by-Step Installation Guide

Once you have all the components, it's time to install your low voltage landscape lighting system:

1. Install the Transformer

Choose a location that is protected from the elements but easily accessible. Garages and sheds are ideal. The transformer should be connected to a GFCI outlet and mounted at least 6 inches above the ground.

2. Run Wiring to Fixture Locations

Start at the transformer and map out a path to run your main wire to lights. Bury wires at least 6 inches. Use junction boxes to connect segment wires.

3. Connect Fixtures to Wiring

Attach fixture wires to main wires using waterproof connectors. Make sure wire polarity matches. Leave 12-18 inches of slack.

4. Secure Fixtures in Place

For path lights, dig a hole and insert stake attached to the fixture. For flood lights, mount on a surface with screws. Use sealant.

5. Adjust and Test Lighting

Aim flood lights. Verify circuits work and make any wire connections as needed. Turn on the transformer and test illumination.

6. Run Any Secondary Wiring to Controls

If adding a timer, dimmer or sensor, run additional 18 gauge wire from the device to the transformer.

7. Make any Final Adjustments

Realign fixtures orcomponents as needed. Confirm appropriate light distribution. Enjoy your lighting!
