This is a set of four smart night-lights from Vont. They plug into your house outlets and come on automatically when the room lighting is low, such as nighttime or in a room with no natural lighting and with the room light turned off. This is done through the use of a light sensor. It is very nice having a little lighting for those late-night trips to the bathroom or fridge. You can aim the led light either down, to illuminate your walkway, or up, to provide dim lighting to the room. They are not weatherproof, so they are designed for interior use only.
They work very well in our home. We are pleased with the purchase and we are sure you would be too.
