Broad Fixture Compatibility Designed to work with low-voltage halogen, incandescent, and LED landscape fixtures, this transformer is a flexible solution for most 12 volt outdoor lighting systems. Automatic Dusk-to-Dawn Operation The built-in photocell automatically switches connected lights on at sunset and off at sunrise, eliminating daily manual control and helping create the appearance of occupancy when you’re away. Multiple Timer Modes for Custom Control Choose the operation mode that fits your needs—timer on/off, photocell auto on/off, or photocell on with timed off—to schedule your low-voltage lighting exactly how you want it. Automatic Overload Protection with Memory If the LED display goes dark while utility power remains present, the unit is likely overloaded. The transformer’s automatic circuit breaker will cut the low-voltage output to protect the system when too many fixtures are connected. After a power interruption, the unit will restore your last settings rather than reverting to defaults. Rugged Weatherproof Construction and Warranty With an IP65 waterproof rating, this outdoor transformer is built to handle harsh conditions. It’s ETL listed for safety and backed by a 3-year guarantee for added peace of mind. NOTE 1. Do not block the photocell sensor; any obstruction can prevent the dusk-to-dawn function from working correctly. 2. Position the transformer's photocell away from other nighttime lights, since nearby illumination can interfere with its operation. 3. Only use with 12 volt low voltage outdoor landscape lighting system. 4. Do not connect to or use with a dimmer. 5. For outdoor use only. Specifications Wattage: 60W Input Voltage: 120V AC 60Hz Output Voltage: 12V AC Waterproof Rating: IP65 Working Temperature: -4°F-104°F
