A low voltage power supply for outdoor lighting is a device that converts standard line voltage (usually 120V or 240V) to a lower voltage level, typically 12V or 24V, suitable for powering outdoor lighting fixtures safely and efficiently.

To choose the right low voltage power supply, consider the total wattage of your outdoor lights, the distance from the power supply to the lights, and ensure the power supply can handle the load with some extra capacity for future expansion.

While you can use a regular transformer, it’s recommended to use a transformer specifically designed for outdoor lighting to ensure proper weatherproofing and safety features that protect against moisture and electrical hazards.

The benefits of using low voltage power supplies include increased safety, reduced energy consumption, ease of installation, and the ability to use flexible wiring options, making it easier to create custom lighting layouts.
