Nitecore EF1 Explosion-Proof Flashlight Combo - CREE XM-L2 U3 LED - 830 Lumens - With Battery and Charger

Can Survive the Harshest of Conditions

The 830 lumen Nitecore EF1 can survive the harshest of conditions, as it is Type II non-mine explosion-proof. It has been created with heavy-duty, rugged uses in mind, such as mining and oil-related industries. Along these same industrial lines, the EF1 can quell potential damage to the flashlight that explosions may cause, because it is ranked as Class D. The lens is a 10mm optical made of epoxy resin, and it possesses ATR/Advanced Temperature Regulation which will change the brightness of the light based on the heat level that is generated. The EF1 is versatile in terms of its usage of batteries; it can accommodate both CR123As and 18650s. The EF1's sliding control power switch will make changing the multiple brightness modes fast and simple. You can also use CR123As as a battery source; this is particularly convenient if you're not near a computer or you are traveling, for example.

Simply Open up the Box, and Start Operating

Simply open up the box, and start operating the EF1 and its included Nitecore NL186 18650 battery, and Nitecore Intellicharger i2, at once. The NL186 has a strong capacity of 2600mAh, and a voltage rate of 3.7V, making it an effective choice for powering your EF1, over alkaline batteries, which typically run up to only 1.5V. The Intellicharger i2 is equipped to handle just about any battery chemistry, like Lithium-ion/IMR, Ni-MH (nickel-meta-hydride), and Ni-Cd (nickel-cadmium). It can charge a broad group of battery sizes, such as AA, AAA, AAAA, C, 18650, 14500, RCR123A/16340, and many more. Your charger and battery are totally reliable, because they are manufactured by Nitecore, a trusted maker of flashlights, batteries, and other such items.
