DEWENWILS 120W Low Voltage Landscape Transformer, Outdoor Transformer with Timer and Photocell Sensor, 120V AC to 12V AC, Weatherproof, for LED Lighting, Spotlight, Pathway Light, ETL Listed Photocell Sensor Transformer

[Built-in Dusk to Dawn Sensor] Landscape lighting that is connected to this transformer will automatically switch on at dusk and off at dawn. By converting household voltage from 120V AC to 12V AC safety voltage using 120W, a safer and more useful electrical current level is produced.
[Countdown Timer] Light control timing has 1-9-hour countdown. With this option, the transformer will turn on at dusk and shut off automatically 1/2/3/4/5/6/7/8/9 hours later.
[Easy to Operate and Install] To select Always On, Auto, or Countdown Timing mode, press up/down arrow. It has Built-in mounting holes, 3.3-foot STJW 18AWG power cord, and direct wall mounting for outdoor walls.
[Memory Function] You won't need to alter the low voltage transformer too often because it will stay in the setting you chose earlier even when there is a power loss. (For the memory feature to function, the transformer needs to be in this mode for at least 24 hours).
[Durable and Waterproof] High performance metal material, corrosion resistant, withstands years of usage, shields the transformer from any extreme weather conditions. Landscape lighting shouldn't use more than 80% of the power pack's capacity in total.
