This set of two motion sensor lights uses solar energy captured during the day to operate the light at night. It has three modes. In Mode 1, when motion is detected, it illuminates on high brightness - 180 lumens for 60 seconds. In Mode 2, the light stays on low - 10 lumens, then when motion is detected, it illuminates on high - 180 lumens for 60 seconds and then returns to low. In Mode 3, the light stays on medium brightness - 30 lumens all night, and the motion detector is not active. The lights feature 100 bright white SMDs. The solar panel requires full sun during the day to charge. Users can mount the lights in a variety of outdoor locations, such as a wall, deck, shed, fence, post and more.
