ALP's biggest, brightest flashlight, the ALPS Mountaineering Spark 240 Flashlight illuminates broad swaths when you're navigating the trail after dark and handling power outages after thunderstorms blow through. The ultra-bright Cree LED packs 240 lumens on its highest setting for impressive illumination in the depths of night. Four lighting modes include high, low, strobe, and SOS for emergencies. It runs on two AA batteries for convenience, lasting up to 15 hours on its lowest setting. Rugged aluminum housing stands up to serious abuse on the trail while sealing out moisture and rain showers, as backed by its IPX-7 waterproof standards.
