We first came across the KLARUS brand of flashlights and tactical torches over ten years ago and have had a couple of models from them in the gear locker ever since. Our most regularly used flashlight, whether it has been for every day use or rifle mounted for lowlight situations, is an original grey bodied KLARUS XT11; this wonderful taclite has given great service and is still going strong but we were excited to hear that it has been seriously upgraded!

The KLARUS XT21X PRO tactical flashlight has an impressive maximum output of 4400 lumens from the NEW CEE XHP-70.2 P2 1A LED. The flashlight is powered by 1 x 21700 li-ion battery and is rechargeable via a type-C USB port found at the head of the light; a Klarus battery and charging cable are included.

The flashlight has a range of outputs, including five brightness levels ranging from 5 to 4400 lumens. To optimise the user experience, the XT21X Pro has two modes offering direct access to different settings. The Tactical mode features one touch strobe and turbo, whereas the Outdoor setting has one touch turbo and low mode, plus SOS via the side switch.


Maximum output up to 4400 lumens.
Dual tail switch and side switch designed to meet all user needs.
Type-C USB fast charging, convenient and fast.
1 x 5000mAh 21700 Li-ion battery included for long-lasting runtime.
Tactical/Outdoor two settings design to meet all scenarios and lighting needs.
Innovative ITS(Intelligent Temperature Protection System) technology, monitors temperature and auto-adjusts output levels in real-time.

This flashlight comes with a 5 year warranty from the manufacturer, Klarus, but we can tell you right now that our original XT11 is still running just as well as when we bought it over TEN years ago!

Good to go.
