You need this light!

I cant say enough about this light. Great light I highly recommend!! I had the 1000 lumen before now this is the one I carry . Brightness and throw is awesome and the case that comes with it is great it has a cup in the bottom that protects the switch from being accidentally turned on. Also battery life indicator double tail switch so you can go instantly to strobe tactical basil 26 700 battery I believe included and charging cord its an all-around great light and I highly recommend it and I have recommended it to my friends I love this light. And if you purchase it here on Amazon from sky ban you get a free battery carrying case and a USB light which is pretty cool not to mention an excellent price and great customer service if you need anything after I called them before just to check.

Another Klarus winner

Super bright tactical flash. Really like the dual tail switches. Only a couple nitpicks: the charge port rubber cover fell off in the first 3 days, so not very waterproof now; head size is a bit large for carrying in carpenter work pants side pocket (but helps dissipate heat well) , & was really hoping for USB-C charging. Minor issues for a great, extremely bright light.

If you are hesitant on buying it, dont be.

At first I was hesitant that it would be too complicated having three ways to activate the light. But, after a few minutes it was really simple and a feature now that I wouldnt want to trade. Its really bright and honestly for the price you will be hard pressed to find something with these features and lumen output.

Excellent tactical flashlight.

Made the mistake of buying another flashlight from a different manufacturer . I have owned 2 Klarus flashlights for 10 years and after several hard falls and exposed to the elements I have never had an issue. So I decided to buy this new klarus to update my 10 year old flashlights and Im am happy with my purchase. Flashlight fits and feels great in hand. Has some weight to it but it feels good in hand. Brightness is excellent and feels well made. Does not feel flimsy or cheap. Klarus flashlights are worth the money and hopefully this new one will last me a long time like my old ones did.

Very bright and seemingly well built flashlight.i

So far it is the most powerful flashlight that I own. I really can not rate appropriately battery life. This flashlight impressed me enough to order ten, that is right, ten more for all the male family members for Christmas. They arrived yesterday. I hope they all will be as pleased as I am. I noted in opening one of the new arrivals it came with a USB plug in triple led light. Cute and also bright. My initial Xt21X did NOT arrive with this supplement.
