Nitecore EF1 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 strengths. It's also a great  choice to put among your emergency supplies. This is a powerfully bright flashlight, with 830 lumens and a 18300cd candela rate/peak beam intensity, with a  long-lasting run time of 150h or 6.25 days when in the low mode that is 4 lumens. The EF1 casts a wide-ranging throw, as its maximum beam distance is 270m,  due to its smooth (SMO) reflector with Nitecore's own "precision digital optics technology." Its LED is a top-of-the-line classic CREE XM-L2 U3.
  Nitecore's EF1 is designed for intense, potentially unsafe environments and is built with many features that will stand up to such conditions. One of these  features is its ability to engage in explosion suppression for Class D substances through its 10mm epoxy resin lens. Class D is a technical classification  used by the National Electric Code (NEC) to indicate that a flashlight, in this case the EF1, is suitable for use in environments that consist of highly  combustible substances like propane, gasoline, naphtha, benzene, butane, ethyl alcohol, acetone and methane. The flashlight body is created for challenging  circumstances, as it is crafted from an aerospace-grade aluminum alloy that has an anodized finish which is ranked as military-grade. The EF1 is rated as  IP67. This IP rating is a bit different than typical IPX ratings, in that it means that your EF1 is not only waterproof, it is also dustproof. In an IP  rating, the first numeral indicates how well-guarded the flashlight is against solid matter, while the second numeral shows how secure the flashlight is from  liquids, such as water. With an IP67 rating, the EF1 is shielded from all dust and can be submersed in water up to 1m.
