The Streamlight Siege is a rugged, cordless, alkaline battery-powered lantern featuring C4 LED technology, red and white LEDs, with five output modes and a battery level indicator built into the on/off button. With the outer lantern globe in place, the light will float. Use the lantern with or without the outer globe cover. Remove the outer globe and hang the body upside down by the D ring for large area lighting needs. Battery replacement is a breeze with the center post orienting the battery cover correctly every time.
