It is a very good light. I am absolutely stunned by the brightness of this light judging by the size of this light. Do note that it can be hot after a while but u still have around 30secs to use before getting too hot . It is sad but understandable that it can only blast turbo for around 12 secs. It is perfect for edc but if anyone wanted it for law enforcement , i would not suggest this light.;

T4K - trickster!T4K is the first product I bought from Nitecore, I watched the video in regards to the mini Flashlight, and comparison when i recieved it , it’s very good. You recieved what you see in the product video. I recieved what I expected. Good job Nitecore Singapore.I dropped the mini flashlight 3 times in my job so far within the first two weeks after receiving it. The metal case came off a little bit but not really a significant damage, the mini flashlight is still intact.Looks like I’m gonna be a regular customer .I just want to say, if it’s possible make it more drop proof or impact resistant. Otherwise the overall rating for me is 5 out of 5.Thank you.

Good flashlight

I wanted this flashlight so bad and now it's here. Awesome quality and performance. I only have it for 1 week so no long run testing. But so far it is amazing.A little bit too expensive for what it offers though, probably wouldnt buy at regular price but its a very good edc flashlight.The specs are not mind blowing and could use an intermediate level between 200 and 4000 lm. I like the lockout mode as it prevents the flashlight from accidental activation.The shipping went back and forth between Texas and Illinois for 4 days which is very wastefull of time and resources.Thank you for the product Nitecore.

Good light. Fatal flaw.

I bought this about a month ago to have a good bright pocket flashlight. And it attaches well to the keychain. Probably a little bit chunkier than ideal. It is very bright which is good. Unfortunately, the buttons are such that putting it in your pocket means you will frequently sit on it and turn it on. It gets so hot literally to burn. It burned a hole through my pants. The only way to avoid this is to put this in lock mode, but then it takes a combination of button pushes to turn it on. So far it has burned me mildly many times, and burned a hole through my pants once. I would not buy it again. fatally flawed.

Great light and great customer support.

Is there a smaller light with this much power? As a personal security flashlight, having 4k lumens on tap is a winner. Practice with the unlock, and I advise unlocking before entering a situation requiring diligence. But do use the double-lock to prevent accidental burns. 4k is no joke!

Just like the name says

Very small (as the name implies). I don’t think I’ll use the 4000k often, if at all. That feature is simply for bragging rights. The OLED user interface is logical. The 1-lumen setting is nice to hang in a tent. It’s basically a small max 200-lumen light and, in that regard, it excels.

Meh..

This light is pointless and redundant as long as Nitecore is selling the TUP. The true standout is the 4000 lumen flash which you can only use for 10 seconds max and using it will rape your battery as this light really isn't built for that level of light output. It's also bulkier than the TUP which was already pushing the line for something that can actually fit in your pocket. The fact that it's USB-C is a nice touch but doesn't justify the extra money to get it over the TUP. The 4000 lumens is impractical which essentially makes this a 200 lumen EDC. If you're interested in a light like this, get the TUP instead.

Perfect Camping Light

1) Solid metal construction with a built in low profile metal clip. Fits perfectly on a ballcap brim to use as a headlamp. Securely fastens and doesn't slide around or come off.2) Brightness settings that are actually useful. Most of the time, I'm not looking for anything crazy - just some good ambient light around the campsite (1 lumen for the tent, 15 for sitting outside in the dark, 65 or 200 for a headlamp or handheld flashlight depending on how I'm trying to save battery. The 4000 lumens is great - see a pair of eyes staring back at you, Boom - completely illuminated and you can see what it is.3) There is a true locking ability to the light so that it doesn't turn on in luggage or your bag - there is nothing worse than getting to a location with a dead ... More1) Solid metal construction with a built in low profile metal clip.

Also the "DEMO" mode where it turns off after 30 seconds offers a couple levels of protection so you don't end up with a dead light at your campsite. Love this functionality.

Perfect EDC and Key FOB belt clip

I kinda hate Nitecore for making this, cause I've practically bought one each time there is a sale. This thing is a perfect companion for my vehicles key FOB's. I just basically use this as expensive belt clips... Although I must warn people who want to do this too. AVOID LEANING ON IT. The body construction is two metal halves that can misalign if you put too much pressure to the body sides, this can result in a cracked lens and button issues. I know this from experience...

Power in a small package

The light is not only bright but extremely powerful for such a small device. At full power (4K Lumen) the light can set thinner paper on fire. Even beaming the light on my skin is very hot. Overall I love the light construction quality and the fact that it is rechargeable. I do wish their was a flap on the USB-C port to keep water out but that is the only negative thing I can say. Pound for pound its one of the best lights out on the market at such a small form factor.
