Excellent multi purpose light

Product Reviews:
Pros:
Cons:
I really like this light. 21700 battery for longer run time, an interface that lets me disable the side button and set the two tail cap buttons to turbo and moonlight, and a nice lanyard hole. Super bright, nice beam pattern. Quickly becoming one of my favorites.

Incredible power

My first over 2000 lumen flashlight and I’m impressed. TheXT21X is a well made light. All the functions are easy to command in both side and back switch. Light throw is amazing, this thing lights up my yard, my neighbors yard and a few yards to boot. This light will get hot pretty quickly, after about five minutes you’re going to want to back it down from 4000 lumens, which is alright since you have 5 different settings. Time can only tell on durability, but having a 5 year warranty backing it up helps. I wish they would come up with a nice polymer holster that could be adjusted for more than one light. I give it four stars, because they need to work on heat dissipation other than that I love it. Nice carry light that will definitely blind any attackers that come you way.

Fl

It is NOT DOA. You must further tighten the tail cap!!!

Pros:
Cons:
The slightly increased diameter of the body is more comfortable in the hand and this is the first Klarus with a dual switch tail cap where you do not accidentally reduce the output of the light by inadvertently pressing the strobe/adjust button right after you press the main on/off center switch. I like it very much and would love to see a 26650 version. I also want to mention that Flashlitz offers outstanding customer service. in the past they have gone far above and beyond to help me purchase specialty parts.
