What's In a Low-Voltage System

Landscape lighting typically relies on stepped-down power from your house.

Transformer: Reduces 120-volt household current to a safer 12 volts.

Bulb: Determines a light's brightness, color, and beam width, as well as electricity usage.

Fixture Housing: Protects bulb from elements and helps shape light beam.

Stake Holds the fixture in place.

Cable: Carries current to light through fixture's lead wires. Underlit trees and accent lights aimed at the facade create an inviting post-sunset atmosphere around this home.
