Whether used for camping, trick or treating, or power outages, this Etekcity 4 Pack Collapsible LED Camping Lantern with 12 AA Batteries will provide up to 12 hours of bright omnidirectional LED lighting to see your surroundings. When the battery power of the lantern runs low, the brightness will dim to an energy saving mode to provide longer lasting illumination (up to 4 hours of low power usage). It’s lighter, brighter and more portable than most flashlights while still featuring the rugged durability to withstand the outdoors. The military grade exterior is water resistant for more practical use in a high range of environments. It saves on time, energy, and luggage weight with simple designing and practicality.
