Easy-to-install light-string system adds the sparkle of small LED lights beneath your table umbrella for nighttime entertaining. You and your guests will enjoy soft, diffused lighting that easier and safer to use than torches, and less expensive than globe lights. Takes only about 30 minutes to put up at first, but then you will never have to take them down, even when the umbrella is folded up and stored. If one bulb goes out, others remain lit. String has eight 30,000-hour amber LEDs per rib, for a total of 64 lights. Includes battery case and pole adapter; four batteries not included.
