Installing and Wiring a Landscape Lighting System

Now that you have selected your power pack (transformer) and selected your fixtures and lamps you are ready to install your Outdoor Lighting System.  This process has been simplified by using low-voltage lighting and the entire process can often be completed in an afternoon.

Steps To Installing Your Landscape Lighting System.

1. Select Location For Your Transformer –  Your transformer should be installed on a GFCI outlet, and should be in a location that is logical for your lighting system.  If you are lighting areas in the front and back of your property, a location on the side of the house would be best.  You should also try to locate the transformer on the side of your property that will require the least amount of wiring under obstacle such as driveways and walkways.  Please avoid using extension cords for your transformer installation.

2. Plan Your Wiring Requirements –  We recommend using 12 Gage Lighting Wire for wiring your Landscape Lighting system.  Lights should be connected in parallel with one side of each lamp being connected to the “COM” terminal and the other side to the “12V” terminal.  There are several options for wiring Landscape Lighting and all will generally be effective.  Here are a few sample Installation techniques:

  • “T” Installation:  This is often the recommended method for installing Landscape Lighting wiring.  Using a “T” configuration allows for more equal distribution of power throughout the lighting system.

Using our model home example (below) we have incorporated both the “T” and Split Load methods to achieve a well balanced wiring plan.

3. Install Landscape Lighting Fixtures –  As mentioned above all lights can be installed in parallel with one side of each lamp being connected to the “COM” terminal and the other side to the “12V” terminal.  See illustration below.
