It comes with white LEDs offering three different luminosity levels: high output at 340 lumens, medium output at 175 lumens, and a soft glow output at 33 lumens. It also includes a red LED that not only aids in the preservation of night vision with 10 lumens of consistent light, but also can signal emergencies with a 10-lumen SOS flashing mode.Its versatile design allows removal of the cover for wider light dispersion. The lantern can be used upright, or hung from its D-ring, located on either the base or top of the lantern, to provide lighting from above. It features a power button that\'s neatly recessed to avoid unintentional activation, and includes a handy battery level indicator. The Siege Lantern is buoyant with its outer globe attached and is waterproof up to a depth of one meter.
