The NiteCore Explorer EA1 Flashlight is a tiny titan of lighting power, a true pocket flashlight with some amazing throwing power. This waterproof LED flashlight is a real pocket thrower that gives you a maximum out put of up to 180 lumens from its CREE XP-G (R5) LED bulb, powered by a single AA battery. The NightCore EA1 Explorer Flashlight features sophisticated power management with a high efficiency circuit that enables maximum runtime of up to 80 hours, and 5 brightness levels to suit your needs - not to mention momentary-on strobe and SOS modes for emergencies. For low lighting levels, you can preserve your night-adapted vision with the secondary red light mode (0.2 lumens), making the NiteCore Explorer EA1 LED Flashlight an ideal choice for exploring at night, caving, camping and stargazing. This NightCore Flashlight is great for recreational use, but it's built to military standards, with an aero grade aluminum alloy body that's HAIII military grade hard-anodize finished, and a stainless steel bezel retaining ring that protects core components from damage. And since it's made for the outdoors, the NiteCore EA1 Explorer Micro Flashlight is waterproof to two meters' depth.
