Installing low-voltage landscape lighting in your backyard is an easy way to enhance the beauty and ambience of your outdoor space once the sun goes down. With a few simple steps, I transformed my dull backyard into a gorgeous nighttime oasis.
Choosing the Lighting
The first step is selecting the right lighting kit. I recommend low-voltage LED lighting, which is:
-
Energy efficient - LED bulbs use up to 90% less energy than incandescent bulbs. This saves money on electricity bills.
-
Long lasting - LED bulbs can last up to 25 times longer than incandescent bulbs. Less frequent bulb replacement is needed.
-
Flexible - Low-voltage LED lighting kits come with everything I needed in one package. The low voltage makes them safe for DIY installation.
I opted for a complete 12V outdoor lighting kit which included 8 LED spotlights, low-voltage underwater lights for my pond, LED light strips to highlight trees/pathways, a transformer, and all necessary cables.
Planning the Layout
Next, I mapped out a lighting plan on paper indicating where I wanted to place each light fixture. Key factors to consider are:
-
Highlighting key architectural or landscaping features - I accented my large oak tree with an uplight and used spotlights to showcase my flowerbeds.
-
Illuminating walking paths - Light strips along the edges of my patio and garden path provide safe illumination at night.
-
Creating ambience - I placed spotlights and puck lights strategically to create an inviting ambience for evening entertaining on my patio. Accent lighting in trees adds a magical touch.
-
Ensuring full coverage - Lights spread around the perimeter and corners eliminated dark spots.
Installing the Transformer
With my layout planned, it was time to install the 12V transformer. This low-voltage converter plugs into a regular 120V outdoor electrical outlet and converts the current to 12V to power the lighting system.
Location is key - I chose a spot near an outlet on the side of my house, mounted the exterior-rated transformer about 5 feet off the ground, and confirmed it was protected from the elements.
Running the Cables
Next came the fun part - running the low-voltage cables from the transformer to each light location. Here are some tips:
-
Use direct burial low-voltage cable. It is designed to be buried shallowly in the ground. No conduit is needed.
-
Lay out the light locations and map the most efficient cable paths between them. Avoid sharp bends in the cable.
-
Bury the cable 1-3 inches below the surface. Use a flat shovel to create a shallow trench.
-
Leave about 12 extra inches of cable at each end to connect the lights.
-
Use cable clips to attach the cable neatly against walls and surfaces.
Connecting the Lights
With the buried low-voltage cable in place, I was ready to install the LED lighting fixtures. The process was simple:
-
Mount each light fixture as desired (in the ground, on walls, in trees, etc.)
-
At each light location, leave some slack in the low-voltage cable to make connections.
-
Use gel-filled wire connectors to attach the cable wires to the fixture wires. Ensure tight twist-on connections.
-
Use exterior-rated silicone to further seal/waterproof all connections.
-
Turn on the transformer and test! Make any adjustments to light positions or angles.
Transforming My Backyard
Following the steps above, I successfully installed low-voltage LED landscape lighting to create an amazing backyard oasis at night. The strategic uplighting and downlighting accentuates the landscaping and architecture beautifully.
The ambience is perfect for evening barbecuing and entertaining. The illumination along walkways also improves backyard safety and security when taking the dog out late at night.
Installing this landscape lighting system is one of the best improvements I've made to my home. The backyard was transformed from dull to dramatic with just a day's work. Low-voltage LED lighting is an easy DIY project that pays off in beauty and enjoyment for years to come.
