Low-Voltage Landscape Lighting in Central Florida
The backbone of professional residential landscape lighting — 12V systems that deliver commercial-quality results at safe voltages, with multi-tap transformers and photocell controls built for Florida's climate.
What Is Low-Voltage Landscape Lighting?
Low-voltage (12V) landscape lighting operates on a transformer that steps down standard 120V household current to a safe 12 volts. This voltage level means the cable can be buried shallowly, the fixtures run cool, and there's no shock hazard from accidental wire nicks during landscaping work. Virtually all professional residential landscape lighting in the US uses 12V systems.
The transformer is the heart of the system. A quality multi-tap transformer allows each circuit to be tuned to compensate for voltage drop over long wire runs — the difference between even, consistent light across the property and dim fixtures at the far end of a run.
Low-voltage LED fixtures also cost significantly less to run than standard 120V landscape lighting. A typical residential system running 6 hours per night uses very little electricity — most homeowners see less than $3 added to their monthly electrical bill, a fraction of what comparable line-voltage lighting would cost.
What It Covers
- Multi-tap transformer sizing and installation
- Direct-burial cable routing for all fixture zones
- Voltage drop calculation and tap selection per zone
- Photocell and timer programming for automatic dusk-to-dawn operation
- Smart hub integration for app-based zone control (optional)
- Dramatically lower energy costs — 12V LED fixtures use a fraction of standard 120V lighting power
How We Install It
- 1Load Calculation — We total the wattage of every planned fixture and size the transformer with 20–30% headroom for future expansion.
- 2Zone Layout — Fixtures are grouped into zones by area and wattage to keep each circuit within acceptable voltage drop limits. Longer runs use heavier-gauge cable.
- 3Cable Burial — Direct-burial 12/2 or 10/2 cable is laid 3–6 inches deep beneath mulch or lawn. All splices use waterproof silicone-filled wire nuts.
- 4Commissioning — We measure voltage at the most distant fixture on each zone and adjust transformer taps until every fixture reads within the 10.8V–12V operating range.
Florida Considerations
Florida's sandy soil and aggressive irrigation schedules accelerate low-voltage cable degradation if the wrong cable type is specified. We use only listed direct-burial cable rated for wet locations, not generic landscape wire from big-box stores. Transformers are mounted at least 12 inches off the ground to prevent flooding from summer storms and irrigation overspray, and positioned out of range of regular lawn maintenance equipment.
