This solar patio umbrella has everything needed to enjoy time outdoors and out of the sun. The tilt and crank functionality can conveniently position the umbrella at just the right angle and makes it easy to close and open it. The umbrella features a solar panel that powers the 24 LED lights located on the steel ribs, making socializing or relaxing under the umbrella day or night enjoyable. The lights operate via a switch on the upper crank housing. When fully charged via solar power, the lights will last 8-10 hours. The large 9' umbrella diameter makes it a great size for any 42"-54" outdoor dining table and chairs. With a standard 1.5" diameter pole, use the patio table umbrella with solar lights with any standard umbrella base (not included) and dining set (not included). In addition, the umbrella is engineered to last with a black, powder-coated aluminum pole for resistance to rust, steel ribs for maximum support, and 100% polyester fabric for the umbrella for extra durability.
