This set of six Solar Power Dusk to Dawn Area Light with Motion Sensor is perfect to use in my outdoor courtyard. I place them lower to the ground and they capture any movement of nighttime “critters” which may be visiting. Of course, they will come on when people pass as well. They stay on for several minutes and then shut off once all movement has stopped. Great for alerting any activity occurring! I especially like the fact that these lights also illuminate from the sides; so plenty of light is given off !
