Buying Guide: Key Purchase Considerations
Power capacity: Calculate total wattage of all fixtures and choose a transformer with a buffer (typically 20-25% extra).
Voltage output: Most LED landscapes use 12V; some fixtures operate at 14V. Confirm compatibility with your lights before buying.
Sensor and timer features: Dusk-to-dawn sensors reduce standby energy; countdown timers help automate lighting for security and ambiance. Memory functions can retain settings after outages.
Zones and wiring: If you plan multiple independent circuits (e.g., front path, backyard patio), select a unit with multiple independent outputs or add programmable controllers.
Weatherproofing: Look for outdoor-rated enclosures and IP ratings or ETL listing to ensure durability in rain, snow, and heat.
Installation and control: Wall-mount compatibility, mounting holes, and included cords matter for clean, safe installations. Wi‑Fi or app control adds convenience for remote management.
Compatibility: Ensure the transformer supports your fixture type (LED vs halogen) and notes about dimmers or specific transformers not supporting certain bulbs.
Reliability and safety: Overcurrent protection, overload safeguards, and UL/ETL listings indicate built-in safety features for outdoor use.
