I have Fenix, Acebeam, Olight, Nitecore, Surefire, Anker and Streamlight. This is my first Klarus and I have been using it for about 3 months now.

Is it 3200Lm? Not sure, but comparing to my 2000Lm and my 4000Lm torches, visually it is brighter than the 2000Lm and close to the 4000Lm.
The weight is nice and balanced in the hand. The clicky and push buttons are responsive.

Size/height is on par with all the brands I mentioned above for a torch in the 2000lm plus range.
Charging is micro-usb, charge time is very reasonable compared to all the others I own.

Price point is lower than the bigger name brands in the 2000Lm or better range.

While this is my first Klarus, It is not my last. this is a great buy in the 2000Lm plus category

My husband highly recommends this tactical flashlight. It is his favorite. He loves the easiness of charging it, and he loved how bright it is no other of his flashlights can compare to the 4400 Lumens. It really stays charge for a long period of time. He also enjoys using the strobe lighting. He had one from 2019 but the battery went and hold charge anymore and it would hold a charge. So he upgraded to this new model.

I got this flashlight as my first 21700 flashlight to try out the new format which has higher capacity than the usual 18650, and since it is included, and rechargeable inside the light, no need to worry about another charger. I have bought Klarus lights before and the quality was always second to none, and I trust the brand.

The control is the usual Klarus dual-switch which allows flawless tactical control, and with the 4000 lumen output, this light will turn night into day easily. The duration of the High output, I think, was definitely helped by the 21700 battery as it doesn't show any obvious step-off in output, and the battery should be able to support it longer compared to the smaller 18650.

Quality is the usual Klarus, smooth anodizing, no faults on the lens and beam pattern.

The light is slightly thicker than the 18650 version, but that's to be expected and not a distraction. The UI, as expected, can be switched between Tactical and Outdoor modes. My preference is for the outdoor mode since I'm a couch commando.

Highly recommended as this is a proven product, upgraded with the newest battery.

I do not normally write reviews but this is one fantastic flashlight. The outstanding features are:
1. 4000 lumens- it lights up my entire back yard like daylight- it has a stronger centre light core with an cover arc of 90 degree surround light with about a 15% less bright drop-off towards the edge of the light circle. Other comments have said there is a yellowing of the light, I only see a bright white light. Unlike my Nextorch, Aside from breaking this and having to replace it, I will never have to buy another flashlight!! Caution: do not look at the light- it could blind a person.
2. Size: the same as my other torches, but a bit thicker with the larger rechargeable battery. Weight is easy to handle, can slip into a jacket pocket easily and comes with a tie handle and its own holster.
3. Love the 3 different on-off buttons- very intuitive to use, just practice a bit- for example, the button at the back- I have my thumb on it- very useful if you want just a faint bit of light- it cycles from a “moon-glow” amount (release it in under a few seconds & it goes off, continue to hold it & will stay on without any more pressure, then can be click cycled upwards in strength. Main one on barrel: click to cycle dim to bright- have fun!!
4. Has a real quality feel and appearance. My old Nextorch - have to unscrew the head to recharge- is now not able to screw past the o-ring so I doubt if it is waterproof now. The Klarus has no such problem- the recharge port is tucked away under a tight rubber seal (next to my thumb in the other photo).
5. The only down side is that the light gets warm pretty fast when using it on the real brightest setting, which I guess is understandable. Then it is great as a pocket warmer(once switched off!)
6. Finally it comes with a recharging cable- USB to Android type socket on the flashlight under the rubber flap - initially a bit of a thing to get it in & out but with use should ease up.

This is a quality product, very pleased with the Craftsmanship & functionality of this light. The features & extra spill are what sets this light apart from others. I had to play with it a little as the directions & actual functions didn't quite match up but not a big deal. It's a light, not rocket science :).

The brightness is great, this is my go to light of I want to light up EVERYTHING! the beam is certainly good but the 4000 lumens comes from a couple levels of "spill". You will certainly see everything in front of you, not just some small beam or "hotspot". This sucker is gonna light up everything far & wide, low & high. For that reason, this light is perfect for when you need to see more than just a small area. The beam is still good though & you get a good deal of throw considering the pattern is so wide. You'd almost think you were dealing with multiple LEDs the way the spill seems to be very bright while still staying focused for a considerable distance. 5/5 for brightness

The carrying case is very nice, & comes with a quality 21700 battery (not proprietary) & extra seal. Clip on side is also quality. So 5/5 for all that as well.

Functionality is great, you can turn it on/off, by both the tail switch, the tactical switch or the side switch, 3x options with different shortcuts. Plus your strobe & sos of course. Can be charged with battery inside the light, nice occasionally when your packing or etc & don't have a battery charger station. Has the button AND tail switch lock out, no worries accidently turning it on in your pack! As far as functionality goes, I can't think of anything else you could possibly want in a tactical light, it's a solid 5/5 on functionality.

Quality is great, seals are good, nice design, hard not to love this light!

The only thing I wish they had included is a 18650 cap for this, so I could run those batteries when needed without purchasing it separate but that's getting pretty picky, you can pick those up for a few bucks.
