The Stanley Electrical Outdoor Digital Photocell Light Timer will turn the electrical devises ON/OFF automatically. It has an automatic darkness sensing cell which activates the timer at dusk and turns off at dawn or after 1-9 hours. It has a manual override control button to turn on or off the power. There is a power indicator which lights up when plugged in and a grounded outlet. Connected appliances can be programmed to turn on at dusk/off at dawn or operate in chosen increments of time (1-9 hours from dusk). The timer will ensure your lights or appliances won’t be on during the day when it isn’t necessary, avoiding wasted energy to save you money on your electricity bills. Programming can be completed in a matter of minutes and will repeat daily.
