Battery-powered light with three super efficient flickering amber LED bulbs. Two CR2025 batteries included; lasts 12+ hours. Compare to other LED lights which use expensive and bulky regular batteries, which are not included. This is the most efficient and compact LED light on the market. Features an On/Off switch and a 10-inch flexible cord for hanging. Illuminates all of our lanterns up to 36 inches in diameter. When using with 24-inch-plus lanterns we recommend 2 or more per lantern for a brighter light. For 30-36 inch lanterns we recommend using 4 to 6 LEDs per lantern. While these battery-operated LED lights are not intended to provide the primary lighting for an event, they are perfect for convenient, decorative accent lighting!
