The Nitecore P20i is a versatile and powerful torch built with military and law-enforcement use in mind.  Paired with an upgraded 21700i battery, it can provide up to more than 50 hours of uninterrupted illumination on low mode and its dual button design makes for easy one-hand operation.  The non-linear strobe patterns cause dizzying effects, very helpful to get through in tough situations.  The front is equally equipped with hard aggressive pongs which could be a life saver as well in emergency situations.
