The Solar Powered Patio Umbrella provides shade during the day and light at night. During the day, when the sun is beating down, a solar panel on top of the umbrella collects the sunlight as power. At dusk, 24 LED lights embedded in the umbrella's canopy and spreaders automatically illuminate for up to 8 hours. If you prefer natural light from the moon and stars, there is also an Auto/On/Off switch built-in.
