The NiteCore EC1 Explorer Flashlight is astonishingly tiny - even more so when you consider its prodiguous light output. Powered by a single CR123 battery, the NightCore EC1 Flashlight is a powerful little pocket thrower that can cast a beam well over a hundred meters into the darkness. This waterproof flashlight gives you a maximum out put of up to 280 lumens from its CREE XP-G (R5) LED bulb. The Nite Core EC1 Flashlight features sophisticated power management with a high efficiency circuit that enables maximum runtime of up to 70 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 EC1 Super-Compact 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 this pocket light is made for the outdoors, the NiteCore EC1 Explorer Pocket Flashlight is waterproof to two meters' depth.
