Save Energy at Home. In Auto Mode, if this plug in night light detects a movement in the darkness, it switches on automatically and lightens your way for a total of 60 seconds after the last movement has been registered. Then it turns off again, making it possible to reduce unnecessary power consumption when you do not need them. According to our calculation, using AUVON motion sensor night lights can save up to 84% energy compared to those without motion sensors. | Comfortable and Adjustable Lighting. You may feel relaxed and comfortable when you see its warm lighting in the darkness. With the two brightness modes design, you can also choose your desired brightness from the High or Medium for different occasions by simply pressing the round button at the top to give you the best experience. | 3 Useful Modes.
