The document discusses the advantages of low-voltage exterior lighting systems compared to 120-volt systems. Low-voltage systems are safer and easier to install as they run on 12-volts of electricity instead of 120-volts. They can be less expensive than high-voltage systems and are more flexible since the wiring can be moved. However, low-voltage systems provide less lighting power and the wiring is more prone to damage compared to high-voltage systems.

1. Low Voltage Lighting Exterior low voltage light fixtures come in a wide range of designs to suit different areas and create different lighting effects. Most fixture types are available in either 12-volt or 120-volt versions. For the homeowner, 12-volt, or low-voltage landscape lighting systems have several advantages.
