Provide a lighted, safe environment at night by using the battery operated Portable Motion Detecting Dusk-to-Dawn LED Blue Night Light. The module has a built in photocell with a dusk-to-dawn that can only be activated in darkness. Once the motion sensor has detected movement the LED will brightly light up the area around, and because it is battery powered, you can take it with you around the house without disturbing others. As the sun rises or the location becomes lit, the module will shut off, extending the life of your batteries. For your convenience you can set the automatic shut-off time between 30 seconds to five minutes. It is a free standing appliance that can be set virtually anywhere you may need light; next to your bed, in the bathroom, hallway or kitchen. This product requires the use of three AAA batteries, sold separately
