Buying Guide
What should I consider before choosing a transformer?
Output type (DC vs. AC), wattage rating, and whether your fixtures are LED-only. Choose DC for most LED landscape lights and AC when you need compatibility with certain fixtures.
Is dimming important for my project?
If you want mood lighting, pick a dimmable driver with compatible dimmers. Check that your dimmer type (Triac, ELV, MLV) matches the driver.
Do I need a dusk-to-dawn sensor?
Sensor-enabled models simplify outdoor lighting by automating on/off cycles and saving energy. Consider whether you need a removable or extendable sensor cord for placement flexibility.
Installation considerations?
Look for weatherproof enclosures, outdoor-rated cords, and mounting options. Ensure the transformer’s wattage supports all connected fixtures without overheating.
What about safety and codes?
Choose transformers with UL or ETL listings and ensure proper 12V DC safety voltage for outdoor installations. Do not exceed listed wattage and follow local electrical codes.
