Featuring evening illumination this 8 by 8 ft offset cantilever patio umbrella opens 64 sq ft of square shade and lights the patio through 32 solar Led bulbs along the ribs. Premium polyester resists sun and weather damage. The cantilever pole sits to the side so the seating area stays open below the canopy. Eight heavy-duty metal ribs feed into a 2.1 inch metal pole and a top air vent steadies the canopy.
