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

[Built-in Dusk to Dawn Sensor] Landscape lighting 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 practical electrical current level is produced.
Tip: Do not use with a dimmer switch. [Countdown Timer] Light control timing offers a 1-9-hour countdown. With this option, the transformer turns on at dusk and shuts 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 includes built-in mounting holes, a 3.3 -foot STJW 18AWG power cord, and direct wall mounting for outdoor walls. [Memory Function] You won't need to adjust the low voltage transformer often because it retains the setting you chose earlier even during a power loss. (For the memory feature to work, 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 use, and shields the transformer from any extreme weather conditions. Landscape lighting shouldn't use more than 80% of the power pack's capacity in total
