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 strengths. It's also a great choice to put among your emergency supplies. This is a powerfully bright flashlight, with 830 lumens and a 18300 cd candela rate/peak beam intensity, with a long-lasting run time of 1h 45min. Its medium setting measures 320 lumens and has a run time of 3h. It has an admirable run time of 150h or 6.25 days when in the low mode that is 4 lumens. It must be noted that these measurements are all dependent on the use of one 18650 battery. The EF1 has the advantage of being compatible with CR123 batteries; however, the lumen output on all settings is the same. For CR123 batteries, the run time in high mode is 1h 30 min; in medium mode, it is 2h 45min, and on the low setting, it's 60h. 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.

Designed for Intense, Potentially Unsafe Environments

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.

Attractive and Sleek, Yet Rugged and High-Performing

With an impact resistance of 1.5m, Nitecore's EF1 is ready for the rigors of everyday wear and tear. Another great highlight of the EF1 is its simple-to-operate switch that slides, located on the body; it is easy to click through for three different levels of brightness. This flashlight also comes with Nitecore's pioneering ATR technology, also known as advanced temperature regulation, which automatically allows the user to regulate the lumen output based on the aluminum shell's temperature. Also part of this incredible little flashlight's structure is its very effective regulation circuit that affords the user a strong and dependable beam. The EF1 also has the unique ability to stand on its tailcap. It's a very attractive, sleek flashlight with high-performing, rugged features.
