The NiteCore EA2 Explorer Series Flashlight is a potent powerhouse of luminosity, a pocket light that still gives you a powerful long-distance beam. This super-compact waterproof flashlight gives you a maximum out put of up to 270 lumens from its CREE XP-G (R5) LED bulb, powered by two AA batteries. The NiteCore EA2 Flashlight features sophisticated power management with a high efficiency circuit that enables maximum runtime of up to 150 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 EA2 LED Flashlight an ideal choice for exploring at night, caving, camping and stargazing. This Pocket Thrower 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 EA2 Explorer Flashlight is waterproof to two meters' depth.
