What "Low-Voltage" Means

Landscape lighting runs on 12 volts — the same as a car battery — not the 120 volts in your wall outlets. A transformer at your house steps the power down before it ever reaches the yard. Twelve volts will not give a dangerous shock, will not start a fire from a nicked wire, and is safe to work around. That is why landscape lighting wire buries just inches deep instead of in conduit two feet down like line voltage.

Safe Around Kids and Pets

Two reasons parents and pet owners prefer low-voltage LED: the voltage is harmless, and the fixtures run cool. Old halogen landscape lights got hot enough to burn — a real concern with curious toddlers and dogs. LED fixtures stay cool to the touch even after running all night. Kids can touch them, dogs can sniff them, and nobody gets hurt.

Safe in the Garden

Low-voltage wire is garden-friendly. It buries shallow, so it does not fight roots. If a shovel nicks it, there is no dangerous shock — just a dead fixture zone until it is repaired. We bury wire deep enough to survive normal edging and aeration, and we use waterproof connectors at every splice so the system shrugs off rain and sprinklers.

What About the Transformer?

The transformer is the one piece that connects to your 120-volt house power — and it lives in a sealed, weatherproof box mounted near your home, out of reach and out of the weather. Modern transformers include overload protection: if something goes wrong downstream, the transformer shuts that circuit down. It is installed to code, on a GFCI-protected outlet, like any outdoor electrical device.

DIY vs. Professional

Low-voltage lighting is one of the safer DIY electrical projects — which is exactly why so many DIY systems exist. But "safe" and "good" are different things. DIY kits often fail on design (the runway look), wire sizing (dim fixtures at the end of long runs), and waterproofing (corroded connections in a year). A professional install gets the electrical details right: proper wire gauge, voltage-drop calculations, sealed connections, and a transformer sized with room to grow.

Frequently Asked Questions

Can my kids touch the lights safely?

Yes. Low-voltage LED fixtures run cool to the touch and the 12-volt power is harmless. It is one of the safest outdoor electrical systems around children.

What happens if someone digs into the wire?

Nothing dangerous — 12 volts will not shock. The affected fixtures just go out until the wire is repaired. We bury wire to survive normal gardening, and we repair nicks quickly.

Is the transformer safe outdoors?

Yes. It is a sealed, weatherproof unit mounted out of reach, connected to a GFCI-protected outlet, with built-in overload protection.

Do I need an electrician to install landscape lighting?

The low-voltage yard work does not require one, but the transformer needs a proper outdoor outlet — which we coordinate. Our installs meet code throughout.
