Some MaxLite LED Outdoor & Landscape Lights have motion sensors, but not all fixtures will. Motion sensors help you save even more energy with your LED lights because they are only triggered on when there is movement in a certain radius to the light. This will also help you save on your electricity bills because you will be using less energy, but there is also a dusk to dawn sensor that is perfect for transitioning from daytime to night. You're LED outdoor light will automatically turn on and off, which is helpful to keep you hands free!
