ALEKO® twin head solar security light is a cost-effective, energy-saving way to illuminate and protect your home or business. Easy to set up, simply place the solar panel in a place with direct sunlight, and connect to the lights with the 16.4 foot cord. The lights charge during the day and light up at night when they detect movement. The PIR sensor is fast and accurate in detecting motion. Solar powered lighting doesn't add anything to your electricity bill, and saves energy. 2 lamp heads provide duel direction illumination, with swivel and tilt to position them any way you want.
