Buying Guide

Match transformer wattage to total load

Choose a transformer with a wattage rating equal to or greater than the combined wattage of all connected fixtures to avoid overloading and dimming

Prefer LED-compatible, low-voltage models

Select transformers explicitly tagged for LED compatibility to ensure stable output and longer LED lifespan with landscape lighting

Consider dusk-to-dawn sensing

Transformers with dusk-to-dawn sensors automate on/off cycles for convenience and energy savings in outdoor setups

Pick the right enclosure and mounting

Use weather-rated enclosures and landscape-specific mounting to protect the transformer from outdoor elements and simplify installation

Match output type and voltage

Confirm the transformer provides the correct low-voltage output (commonly 12V DC) required by your fixtures and compatible wiring
