Stretches into a Lantern and shrinks into a high powered flashlight!
The UCO Lumora LED Lantern is a compact and collapsible lantern that provides up to 170 lumens of light that is comfortable to read by. Light up your campsite or workspace with the tough, water-resistant Tetra USB Charger + Lantern + Flashlight. Delivering maximum brightness and functionality in a 4.3 oz. package, it’s loaded with 170 lumens and a range of brightness levels. Transform the Tetra into a focused beam by pushing the head down, and then charge your digital devices through its USB charging port.
