Sunsei 24001 Solar Motion Security Light Each security light has 12 integrated long lasting LED lights, and functions with a solar panel, so no electrical connections are required. The included solar panel is equipped with a 16-Feet long cord and angle adjustable mounting plate for best positioning to maximize the sun's rays. The motion sensor detects 50-Degree vertically and 90 degrees horizontally and comes with an Integrated weatherproof on and auto switch. Switches allow you to adjust the sensor's sensitivity and the amount of time the lights stay on after motion is detected (30 or 60 seconds). The powerful, rechargeable Lithium ION battery is used to keep the lights ready at all times and can be replaced down the road, so you can enjoy your purchase for years.
