Perfect for what I needed!. Sherry. Cordele, GA. Tue Apr 21 2026

Came very nicely packed and the build quality is very good. I did not want a plastic outer body because had an old one break apart, and this is quite sturdy. Setting it up was a breeze and the instructions come in quite handy. Until now its quite weather durable and with the strong shell I don’t think it will have issues. Overall a good purchase !. Sg.

Dusk to Dawn Sensor The inclusion of a photocell sensor in this transformer ensures that the landscape lights connected to it will automatically switch on at sunset and off at sunrise. This eliminates the need for daily control and allows you to enjoy worry-free lighting. Additionally, when you are away, the lights can create the illusion of someone being at home, enhancing security measures. IP65 waterproof rating lets this outdoor landscape lighting transformer have better performance in harsh weather. ETL listed product make your life safer. Come with 3-year warranty for your benefit 2H/4H/6H/8H Countdown Timer With this transformer, you have the option to set a countdown timer for your low voltage lighting to automatically turn off at night. This allows you to customize the duration based on your specific requirements. To simplify the setup process, we suggest connecting all the landscaping lights that need to be turned off simultaneously to the same transformer. Automatic Overload Circuit Breaker In the event that the LED display is off but the utility voltage is still present, it indicates a significant overload on the transformer. To prevent any potential damage, the automatic overload circuit breaker will automatically shut off the low voltage output of the power unit if the circuit becomes overloaded with too many fixtures. This feature ensures the safety and proper functioning of the transformer and connected fixtures. In the event that the power to the transformer is cut off, you can rest assured that your last setting will be remembered. This means that when you turn the power back on, the transformer will retain and restore your previous setting instead of resetting it. This convenient memory function allows for a hassle-free experience without the need to reconfigure the settings every time the power is interrupted. NOTE 1. Avoid blocking the photocell light sensor as it may affect the photocell for the dusk-to-dawn mode. 2. Ensure that the transformer's photocell is not installed too close to a nighttime light, as it may interfere with its proper operation. 3. Be sure that the total cumulative wattage of all 12 volt fixtures connected to one transformer is equal to or less than 100 watts. 4. For use with 12 volt low voltage outdoor landscape lighting system only. 5. Do not use with a dimmer.
