Nitecore T4K Review - the World's smallest 4,000 lumens flashlight - but is it any good?

This is the Nitecore T4K flashlight. It is the world's smallest and lightest 4,000 lumens flashlight. In this review of the T4K I run through all the features of this blindingly bright (4,000 lumens is insane at this size!) flashlight so you can decide if it is worth all the hype. When it comes to everyday carry (or EDC) I carry a very small and lightweight flashlight because I don't expect to need it much during the day. But for Everynight Carry - this could be the one!

This channel is here to help you find great travel and carry gear on the back of solid and detailed reviews along with years of experience. I also hope to give you ideas and inspiration when it comes to everyday carry gear, travel gear and gadgets, which make life a little bit easier and perhaps more fun.

I welcome any feedback on my videos or the channel in general. Thank you for taking the time to read this.

Product Sourcing:

When it comes to sourcing a product for review, I will usually either purchase an item personally or reach out to a supplier requesting a sample for review. Most suppliers, after seeing the channel, are supportive if they are confident in their product, appreciating the value of greater exposure.

I am sometimes asked to review a product by a supplier which I will only agree to if the product fits the channel and I believe will be of interest to you, my audience. Also the product needs to be worthy of a review. It is not in my interest to review inferior or poor quality products and therefore as you might expect many requests are politely declined.

Any sponsored videos (paid for reviews) are clearly stated as such so there can be no misunderstanding. Even with sponsored reviews I will only agree to a sponsorship on products and services which I believe will be of genuine interest to viewers.

I will always make reference in the video to products which have been provided for review by a supplier and I always make it clear to the supplier that they cannot influence or be involved in the review in any way if they chose to supply a product.

Sometimes a supplier will provide a link to the product or the supplier which I am happy to include in the description. Sometimes I will be provided with an affiliate link so I can earn a commission on sales and this helps to support channel costs but never at the expense of an honest review.

If a product I have reviewed is available from Amazon I will often include an Amazon link in the description. As an Amazon Associate I earn from qualifying purchases. If you purchase a product or service with the links that I provide I may receive a small commission. There is no additional charge to you.

Thank you for supporting my channel so I can continue to provide you with regular reviews, thoughts and ideas and (hopefully) inspiration!

Great review! I had the Nitecore T4K for about 6 months now and its battery is still at full capacity. I had the Imalent LD70 way back in January but it failed and doesn't work anymore. So, I got the T4K last March and until now it still works perfectly fine. Worth the price :)

Thank you Jon for all the great videos. Keep up the fantastic work, you are super!😉👍

What a brilliant review....couldn't be any better !!...👏👏

Thank you Jon for all the great videos. Keep up the fantastic work, you are super! 🔥

I really like how your videos are produced (lights, camera angles, sound…) and the fact that you always have a clear and interesting talk. I’m sure you will get many more subscribers soon and I’m one of them. 😁 Greetings from France 🇫🇷

Good review Jon. I have a few Nitecore products and have always been impressed by their performance and quality. I really like the look of this one and the 10 second bursts in the highest mode seems a sound idea. I can see it residing in a jacket pocket during the darker months. The price you quoted does not seem excessive, I think Nitecore have a winner on their hands here.

[vidzilla]

Another fantastic review! I have owned the T4K for a year now. No problems and worth the money.

[dougbotimer]

Great review, I especially appreciate your analysis of what this product is and is not, and why it works for you I have the TUP 1000 lumen and think of it the same way. It is my EDC light. The functions and operation work very nicely. Another Nitecore 4K lumen light is on my radar for a field flashlight, the E4K. Also, the clip does work great on my cap bill, the main reason it is my EDC.

[Solaar_Punk]

Thanks for the video, a nice, detailed review. 👍

[RomboutVersluijs]

One thing i missed it s the lock mode 2, i believe this model has that.

Another which would be nice, is when a powerbank is attached, it would actually read that as well. So you get real good time measurement

[FelixCheam]

I bought my T4k before Isaw your review and I agree it's worth the money. Especially the screen.

[evoste]

Agree with you Jon regarding the reality of modern torches that sell on a high lumen count when in fact that is only for a few seconds upto a couple of minutes LED's and batteries have got better but you have to look at the mid modes and look at duration. I have an Olight pro seeker 2 that has 3200 lumen but I have it set on 200 as that is sufficient for most needs. The turbo is usefull in an emergency or self defence.

[MoorlanderEDC]

Hmmmm... I've been looking at this light for a while. I think displays on lights are the future. As function get more advances on lights, the small display makes more and more sence. Awesome content buddy 👍

[theworth]

Just found your channel, , , great stuff... Are you about to do a review on edc belt pouches of good quality leather would really be interested in that too. Keep up the good work Mate..

[stevenhodgson]

Nice piece of kit, very well designed.

[ronbokje]

Got the TUP the 1000 lumen. That’s also a brilliant light, a lot smaller and carry it every day.

[Stoater]

I have the Nitecore TUP and Nitecore Tini 2 which both have
almost the same UI as this TK4.
I bought the Tini 2 as it is a lot
lighter than the TUP.
I use both of these on a neck lanyard and even the Tini 2 puts out 500 lumens.
I've just bought the upgraded Olight
Warrior 3 (2300 lumens) in desert
cam and I've only had the M2R
Warrior in Ocean camouflage for about a month.
I blame Black Friday.
I really like your reviews,
you tell us all we need to know.
I hate it when some of these reviewers throw the lights around.
The manufacturer has already drop tested these lights so why is it necessary to repeat this abuse ?
I'm looking forward to your next review.

I have the 1000 lumen version of this light. I was surprised how much I like being able to see exactly how much runtime is left at each power level. While this wouldn’t replace my Fenix LD30 as an edc due to runtimes and the fact that I like to carry only 18650 lights, it looks pretty cool and I will no doubt add one to my (far too large) collection.

[twrcrew]

i've actually leaned against a stansion on my boat at work with this clipped to me belt and it DID burn the crap out of my shirt and forearm (in feeling. luckily no physical damage). gave me a good scare, and that was IN lockout mode 1. I've been more careful since, and still use lockout mode 1. But I can definitely see a need for lockout mode 2. 10 seconds is enough to start a fire against some paper or light material. as I've done deliberately with many fast food bags over the last few months i've owned this light as I showed others.

[Megamare]

Great review and agree it’s nicely designed . I have the 1000 version too.
But my only concern with this and other Proprietary battery types is what happens after it’s exceeded it’s charge /discharge cycle count.
Is the battery(s) replaceable ( it can be opened), sent to the manufacture (probably not) or meant to be disposed of & buy a new torch? 🧐
