Designed to fit any 8-rib patio umbrella, our IN-LINE light design and “POWER POD” receptacle needs NO recharging, battery replacement or separate light fixture storage and it stays with the umbrella when its opened, closed or stored. If one bulb burns out the rest remain lit. U.L. Listed For Outdoor Use.
