Buying Guide: Key Purchase Considerations
- Wattage and future needs: Choose a transformer with wattage above your total load to allow for growth and avoid overloading a unit.
- Voltage compatibility: Most residential systems use 12V or 12/14V outputs; confirm compatibility with your lights (LED vs halogen) and ensure the transformer supports the correct output.
- Control options: Look for dusk-to-dawn, timer, countdown, and manual modes. Dual-zone models offer independent control for different lighting scenes.
- Photocell sensor: An external or replaceable sensor enhances placement flexibility and outdoor durability. Check sensor cord length for installation convenience.
- Weatherproof rating: Outdoor use requires weatherproof or ETL-listed units to withstand exposure to rain, snow, and dust.
- Installation and wiring: Consider mounting options, included cords (power and sensor), and ease of wiring for a clean, safe setup.
- Reliability and safety: Look for UL or ETL listings and manufacturer warranties to ensure long-term performance and protection for your landscape lighting system.
- Maintenance: Removable photocells and sensor cords simplify replacement and repairs without replacing the entire transformer.
