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 located at the top of the umbrella that powers the 24 Led lights located on the steel ribs making socializing or relaxing under the umbrella day or night much easier. 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"" opening base, use the umbrella with any favorite outdoor seating set! 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.
