Decked out with four C4 LEDs and one red LED. The Streamlight Siege LED Lantern keeps you prepared for almost any nighttime situation. Use the Nightvision preserving mode, and the red LED sheds 10 lumens of light for up to 235 hours - a red light doesn't inhibit your nightvision. On Flash SOS mode, it delivers a 10-lumen signal that flashes on and off for up to 430 hours. This versatile lamp boasts a removable, polycarbonate, glare-reducing 360° cover that softens and evenly distributes light. For maximum brilliance, turn it on high and 340 lumens illuminate a large area for up to 30 hours. On medium, 175 lumens run for up to 70 hours, and on low, the LEDs provide 33 lumens of softly glowing light for up to 295 hours. Durable, polymer impact-resistant construction with a rubber molded base. Rugged IPX7 waterproof exterior allows it to float if it falls into water. The battery-level indicator changes from green, to yellow, to red and to flashing red when batteries are low. Ergonomic handle locks into upright or stowed positions. Incorporated hook. Recessed power button. Runs on three D batteries (not included). Ht: 7-1/4". Wt: 1 lb. 15 oz. (with batteries).
