The NiteCore EF1 flashlight is intrinsically safe and certified with ATEX EX II 2 G Ex d IIC T6 Gb, i.e. Nitecore EF1 is safe to operate with the presence of class 1 group A (Acetylene), B (hydrogen), C (Ethylene) and D (Propane) gases ! This blinding 830 lumen light was made to be the perfect companion for hazardous work such as land and marine petroleum exploitation and chemical industries. Slice through darkness with 295 yards' worth of beam throw. Power your light conveniently with just one rechargeable 18650 battery. Perhaps the greatest feature of the EF1 is its extremely user-friendly functionality. A sliding on/off switch allows the user to select one of three brightness outputs rapidly and easily using one finger.

As this is my first day using the flashlight it works like it should, this light is 3 times cost more than the light I normally use, I hope it’s money well spent. The head light I also ordered doesn’t charge???
