400 Lumen Lantern. This lantern extends from its closed position and immediately turns on when you pull the top up. It Details 2 brightness modes for low and high brightness for up to 400 lumens of white light. The brightness modes change each time the lantern is opened. For even more flexibility, you can operate the lantern partially open for just the right amount of light. The metal handles fold down when the lantern is closed for convenient compact packing and transportation.
