The Klarus XT21X Pro tactical flashlight offers an impressive maximum output of 4400 lumens from the Cree XHP70.2 P2 LED and is powered by 1 x 21700 (included) or 1 x 18650 with the included battery magazine.

The torch is rechargeable via a USB-C port on the side of the light and can be used to charge a mobile phone in emergency situations. 

To ensure the XT21X Pro meets your requirements, it features two programmable settings. The tactical setting offers instant "one-touch" access to strobe and turbo mode, where as the outdoor setting provides an SOS output, plus instant access to low and turbo mode. Both modes offer the five brightness levels which can easily be cycled through via the side or tail switch. 

The Klarus flashlight has a crenulated bezel for emergency use, grip-enhancing knurling on the body, an anti-roll head design and grooves for effective heat dissipation.
