Solar stakes from the store are easy, but they tend to dim quickly and don't last. Landscape lighting installation with a hardwired system gives brighter, more consistent light. A local electrician can set up the power supply correctly, especially the outdoor receptacle and transformer, and help lay out the fixtures. Call to get connected.
How low-voltage yard lighting is put together
Most residential landscape systems run at low voltage. A transformer plugs into or wires to a GFCI-protected outdoor receptacle and steps household power down, then low-voltage cable runs through the beds to each fixture. Because the cable carries low voltage, it can be buried shallower than household wiring, and fixtures are easy to move as plants grow.
The catch is voltage drop. On long cable runs, fixtures at the far end get dimmer than those close to the transformer. Good designs keep runs balanced, use heavier cable for longer runs, or split fixtures into several shorter legs fed from the transformer. The transformer size also has to match the total wattage of the fixtures with some room to spare.
Yards that benefit most
- Front walks and steps where tripping at night is a concern
- Mature trees, stone walls or house fronts worth highlighting
- Garden beds around a back patio that feel dark in the evening
- Long driveways on larger lots and rural properties
- Replacing worn-out solar lights with a hardwired system
Signs an existing system needs help
- Fixtures at the end of a run much dimmer than the rest
- The transformer's timer or photocell no longer works
- Cable exposed by mulching, edging or erosion
- The outdoor receptacle feeding the transformer keeps tripping
- Corroded connections or fixtures that flicker in wet weather
Designing garden and pathway lighting that lasts
The electrician looks at where the transformer can go, usually near an exterior wall and an outdoor receptacle, and whether that receptacle has GFCI protection and a proper in-use cover. If there's no suitable outlet, they'll add one, which is where GFCI outlet installation comes in. Then the fixtures are placed, cable is run and buried, and connections are made with waterproof connectors. Many homeowners also add porch and patio lights at the same time.
- GFCI protection and in-use cover on the source receptacle
- Transformer capacity versus total fixture wattage
- Cable gauge and run length to limit voltage drop
- Waterproof connections at each fixture
- Timer or photocell settings
- Fixture placement relative to walkways, windows and neighbors
Safety first. The low-voltage side is safe to handle, but the transformer is connected to household power and must plug into a GFCI-protected receptacle rated for outdoor use. Line-voltage landscape fixtures, which run on standard household voltage, need the same burial depth and protection as other outdoor wiring and should be installed by an electrician. Before driving stakes or trenching, call 811 so buried utility lines can be marked.
How it usually works
Call and share your yard plans
Call to connect with a local electrician and describe the paths, trees or beds you'd like to light.
Walk the yard at a glance
The electrician picks a transformer location, checks the power source and plans fixture placement.
Place, run and connect
Fixtures are set, cable is buried in the beds, and connections are sealed against moisture.
Aim and adjust after dark
Fixtures are aimed and the timer or photocell is set, ideally checked once it's dark.
In Murfreesboro and Middle Tennessee homes
Middle Tennessee yards take a beating from heavy spring rain, clay soil that shifts and mulch that gets refreshed every year, all of which can expose or nick shallow landscape cable. Burying cable a little deeper along edges and leaving slack at each fixture helps. Larger lots out toward Eagleville and in rural parts of Rutherford County often have long driveways, where voltage drop planning matters more. For ideas, the guide to outdoor lighting ideas in Tennessee is a good start.
