It is Nitecore's latest tactical light and is an upgraded version of previous P10 models. The P10i utilises a Luminus SST-40-W LED to give it a max output of 1,800 lumens and 290m beam distance. This torch is specially designed for tactical application and features their 2nd generation strobe ready technology for instant access to strobe in any mode. The dual tail switch design gives you two buttons on the tail of the torch to change modes and access the 3 brightness levels and strobe mode. The P10i runs off a 4,000mAh 21700 battery (included) but is also compatible with two CR123 batteries and the torch is USB-C rechargeable for fast charging. This torch is compact and lightweight weighing only 84 grams which makes it easy to carry while on duty. Other features of the P10i include the advanced temperature regulation, power indicator, included holster and compatibility with i Series modular extensions including various mounts, remote switch and more. The compact size, high output, dual tactical switch and strobe make this an ideal torch for law enforcement, emergency services, self defence and security.
