Buying Guide
Key considerations when choosing a low voltage landscape transformer:
- Lighting load and number of fixtures: Match the transformer wattage to the total wattage of your lights, leaving headroom for future additions.
- Zones and control complexity: Decide if you need single-zone ease or multi-zone flexibility for different areas of your yard.
- Control features: Evaluate whether you want basic dusk-to-dawn operation, countdown timers, programmable schedules, or smart app/voice control.
- Power output type: Confirm whether your lights require 12V or 14V, and ensure the transformer supports the chosen output to avoid dimming or incompatibility.
- Durability and weatherproofing: Look for outdoor-rated enclosures and UL/ETL listings to ensure safe, long-term use in varying climates.
- Sensor placement: If using a photocell, consider its cord length and whether the sensor can be mounted outdoors while the transformer sits indoors for convenience.
- Installation considerations: Check for easy wiring terminals, mounting options, and included cables to minimize installation time.

A device that converts 120V household power to a safer 12V or 14V output to power outdoor lighting fixtures. It often includes timers, photocells, and multiple zones for flexible lighting control.
Multiple zones help run different groups of lights with independent scheduling or modes, which is beneficial for larger landscapes or varied lighting goals.
Most models offer app or voice control or Wi‑Fi networking. Check compatibility with Alexa or Google Assistant and whether a hub is required.
Many listed models are designed for outdoor use, with weatherproof housings and safety ratings. Verify IP ratings and listings like ETL or UL before outdoor deployment.
Calculate total fixture wattage and add a comfortable safety margin. Higher wattage supports more lights or future expansion, but select a unit whose rating exceeds the current load.
12V is common and supports many LEDs and some halogen fixtures. Verify your specific fixture requirements (12V vs. 14V) and choose a transformer accordingly.
