The Siege Lantern is more versatile than other emergency or camping lanterns. Tough Polycarbonate thermoplastic construction with elastomer over mold and rubber molded base provides stability on slippery or uneven surfaces. It has four white light settings, a red light for softer, less intense light and an SOS mode. Its handle and D-ring allow you to hang it or clip it almost anywhere, upright or inverted. The night vision preserving mode extends run time for emergency preparedness, while the keyed battery door facilitates battery replacement in the dark. It runs for over 30 hours on high and over 12 days on low.
