Installing low voltage landscape lighting is a big impact DIY project. Being low voltage lighting, it is safe to install and use, even for beginners. You can use the outdoor lighting to eliminate paths, dark areas, and steps and add full art dynamics to your yard’s best features and properties, thus enhancing its beauty and look. 

How to Install Low Voltage Landscape Lighting

How to Install Low Voltage Landscape Lighting

Step 1

Before installing the outdoor lighting, search for the light fixtures and landscape lighting wires. Use the 10-gauge wire to install the main lines coming from the transformer to where the lights start and install 10 gauge wires between the lights.

Use a flat-nosed shovel to cut the slot and fold it back to bury the wires well—Burry the wires in the ground at least 6 inches deep to avoid getting damaged when irrigated. You can cover the simple low voltage wires with the mulch or soil in the protected plated beds.

Step 2

In the central location near an outdoor GFCI outlet, install the transformer. Mounting it higher on the post will permit you to alter the change in photocell orientation.

Connect the transformer to the 10-gauge main wire by stripping off ¾ inch of insulation by turning the small strands of wires together. Attach with terminals, as the transformer has a built-in timer and photocell, two circuits, switch, and terminals to set the output voltage. 

Step 3

Make the strong base for heavy path and cone lights from plastic pipe. The function of this base is to give strong footing and give housing to the wire connections. And permit you to make the pole extensions of enough length like ½ inch of copper wire. Do not attach the plastic pipe. 

Step 4

Cover the wires with waterproof material and wire connectors. The wire connectors come with a shield or covering on the bottom, and a blob of sealant inside makes the wires weatherproof. If the lights are in the press in connections, cut them by the strip off ½ inch of insulation and mount the connectors. 

Step 5

Install the path light deep enough by digging the hole so the top of the PVC footing should be on the ground level, with the help of torpedo level to make the light pole even and pack the soil surface around the base. To secure the uncovered wire, use aluminum tent stakes in the bedding areas, and cover it with mulch.

Step 6

Test the voltage of each light with the digital voltage meter, as each halogen light should get 10.5 to 12 volts for a smooth and consistent look and to prevent premature burnout. If the connection is weak, it will show extremely low readings, and if the system comes with too many lights on the circuit. Suppose you want to make minor adjustments using voltage controls on the transformers. 


So while installing the low voltage landscape lighting, the process is not so difficult. Still, one should be careful in installing the system, covering the wires with insulation, and ensuring that the system comes with well-organized ways and materials to avoid short-circuiting and damage.
