The EF1 from Nitecore is a brand-new flashlight that contains state-of-the-art "explosion-proof" technology that sets it apart from other industrial-strength flashlights. It can function as both an everyday carry (EDC) light and a searchlight, so versatility is one of its key strengths. It's also a great choice to put among your emergency supplies. This is a powerfully bright flashlight, with a max output of 830 lumens and a 18300cd candela rate/peak beam intensity, with a long-lasting run time of 1h 45min. The EF1 has the advantage of being compatible with CR123 batteries as well as a single 18650 cell. The EF1 casts a wide-ranging beam, with a maximum beam distance of 270 meters, due to its smooth (SMO) reflector with Nitecore's own "precision digital optics technology". Its LED is a top-of-the-line CREE XM-L2 U3.
