Solar-powered LED lights built into the ribs turn this double-sided patio market umbrella into a shaded gathering spot you can keep using after dark, controlled by a simple light switch. The 13-ft extra-large rectangular canopy in polyester fabric helps shield a sofa, dining table, or lounger while resisting sun and light water. Twelve heavy-duty metal ribs support the 12.3 x 6.7 x 7.3 in frame to reduce shaking in use. A vented top promotes heat dissipation and allows wind to pass more easily for added stability. The smooth crank handle makes opening and closing the canopy straightforward, and a safety pin helps keep it from closing suddenly. A fixing strap lets you neatly secure the canopy when it is closed for storage or when used with a compatible 31-lb umbrella stand.
