Great light. Ran it on multiple 12 hour shifts and charged it during my sleep cycle and it worked great.

Very powerful and compact. The beam goes a long distance. Cool flashlight!!!

Extremely bright! And very compact also. Definitely have to study The instructions to understand all the different settings, but the strobe is easy and the bright light is easy too.

600 meter distance is Amazing for Long ranges.
Klarus XT21X 4000 lumen flashlight is better, when viewing within 220 metets!
Great products!!

It's a great light. Not easy to figure out the dimming feature, but in general I feel klarus makes a MUCH better flashlight for tactical and home use than any other company. I own 12 Klarus flashlights with various batteries or charging modes. I prefer batteries as they can be stored and recharging is not guaranteed in any apocalyptic scenario. Nonetheless. It's a great light. Gets hot fast and the run time is a little short, but would buy again.
