Yes They Finally Did It... 4000 lumens In A Thumb Sized Light! - T4K First Look 

I have no idea how I got to this video, but I'm I did. I feel like I just went through a masterclass of flashlights and flashlight operation. This video quality is amazing, clear to understand, and very informative. I didn't need or want a flashlight, but damn, now it looks like I'm buying myself a T4k. Take my money, my subscribe, and my notification bell. WELL DONE!

I dont know exactly what you do for Nitecore but you do an excellent job explaining and demonstrating their lights. Well done.

This was the cleanliest explanation of "why we design this flashlight, this way"

This channel is truly undefeated. Your explanations, your reasoning behind everything is almost flawless. You don't even have to be a Nitecore fan to appreciate this level of knowledge. Keep at it 💪🏼

This has to be one of the best videos I’ve seen explaining flashlights. Well done and thank you!

You really should get a bonus sir. You have excellent communication skills and a great teacher. You sold me on this company and their lights.

Bro I've learned so much about lights just by watching your video just know. you have earned a subscription and a bell icon my friend. thank you for the information

You’ve just convinced me.... best explanation video EVER... period... no BS... !!

Im am now a fan and customer of nitecore Just from watching this channel

Dude, keep doing video. Love how you explain things. Subbed.

Well done sir, and most educational! Long time Nitecore user since E41/4AA (2015)😃

I wish you could review every single item I have questions about. Good job sir, you are winning.

Im a flashaholic. Lol. I think nitecore and imalent are the best in the biz for pushing the limits. I hv both brands. I dont hv the t4k but i hv imalent ld70. It has 4000 lumens aswell, it is slightly smaller than the t4k. And is traditional flashlight shape. It has 20 lumen, 200,900 and 2000, aswell as the turbo 4000. I would like to get the t4k to compare. If you take photos a lot nitecore has an awesome camera light called scl10 with variable light temperature. My wife does cakes and she loves the scl10 for taking photos. Both companies have great customer service aswell.

Wow, seriously best product description/info presentation ever; followed by an unapologetic but hype free sales ending. A whole lot more companies of all products could learn from this approach.

Excellent, very detailed review. I just found my next flashlight.

That is the right way to really use this flashlight. actually you really don't need to go up to 200lm. Mine i use 20lm most of the time and use 200lm rarely and 4000lm for fast signal. btw i use IMALENT LD70. for comparison, the body is all aluminum and the button is at the bottom part which is the best position imo. its all rounded too so you hold it like any small flashlight out there. this one is a little awkward button position imo. its like you have to hold the flashlight with peace sign finger to properly use it. even if you wear it in your collar, you will still find yourself looking for the button unlike any traditional flashlight where they put it on the bottom.

Such a good detailed review. Many thanks. Going to get one after watching.

Awesome light, but I still wish there was a level in between 200 and 4000 just so there's longer runtime. I think if it was 2500 instead of 4000 it would be much more usable. Still, it didn't stop me from picking one up hahaha!

Well, you talked me into it. I was looking for another light and have a few Nitecore lights, so after watching your video, I ordered the T4K. I just received it a couple of days ago, and - no regrets, I love it!

I own 3 of the tup lights and have been using them for going on 4 years now. I work in a rail yard and use them on a hat bill. It literally is the most useful and best light I have ever owned or used.

What a natural well explained delivery. First class. Deserves a like , sub , and purchase.

Wow I did not expect to learn so much! You have a talent for explaining this field. Thank you very much!

I have their little ti-ni and it's been fantastic. Crazy powerful light for a little keychain thing. I hit my coworker with it in a dark lanroom a few weeks ago and he was seeing spots for an hour. I had to apologize a dozen times on that project lol.

New to torches, but diggin' the heavy Malaysian accent being half Malaysian myself. Good to hear a recognisable voice, thanks for the information.

While I like Nitecore lights and have a good handful of them, I have shifted to Fenix, they just seem to have better throws and lumens packaged in a smaller form factor than Nitecore.

I’m still waiting for nitecore to come out with a LEP (laser excited phosphor) light. Combine a LEP center light with supporting LED lights around the outer edges of the light. You would have the longest throw light with great flood as well. LEP has a throw of around 2400 meters

I really like the tip2 cause it has a magnetic bottom. Maybe add the magnetic bottom to all the small lights?

EXCELLENT review channel. I really appreciate the way you deliver information. I've just found my favorite new flashlight review channel.

This guy knows his stuff .. V precise explanation.....

By far my favorite pocket light. That Turbo is an awesome spread of light when you need to light up an area. Great job Nitecore

Give this man a raise 🙌

Firstly I would like to say that I am glad I found your channel. Secondly I just wanted to share my experience with this light. It's a great light, pure and simple; however, while I was trail riding, this light definitely burned a hole (4 little holes in the shape of the light arrangement) in my shirt. The light was on demo mode and 2nd lockout. Somehow it came on, and burned my shirt.

Small torches like this one are ideal for around camp / in the tool-box or glovebox or handbag or motorcycle jacket pocket - just fabulous.

I bought the T4K and I must say that it is fantastic (like all Nitecore products) I have almost all Nitecore models but I have not yet understood whether once the battery has finished charging cycles if it can be replaced or if you have to throw everything away and buy a new flashlight. I ask why I'm thinking of buying the 10000 Lumen model but since it costs a lot I wouldn't want to throw it away in a few years

Fantastic review. I have 2 older Nitecore flash lights and they still work great but I wanted just what you said ,a smaller and brighter Light .So I brought 2 new Olights .They seem ok no troubles .Now I would like the one you have just shown .It looks like the best light I have ever seen.

Putting this on my work cap at night. No hands

Such a great review! You sold me! Just ordered one. Thanks

Any updates for the new tiny monster series? like TM20K or TM30K. It has been 3 years since the release of the TM10K and we've been all waiting for the new king of turbo lumens from Nitecore.

Great video. Love the jazz background music as well.

Yeap ! Definitely what we need for our camping, hunting and fishing adventures,by Friday I should have at least 3 of those from the website.

Great video, I learned so much, thank you.

Excellent bit of learning for me many thanks

I've got a Volt 1600 Lumens, awesome light but half hour of use on full power and then it takes 5 hours to charge

Just got my t4k last night and im loving it!

Just got my light works great

Thank you for your clear explanation of the functions of a potentially perplexing flashlight.

Idk why this is recommended???? But i want this

Thanks Nitcore, you are best to review your lights! I Buy Nitcore EC4. Its a great one, but to hard for me to understand..

I owned the Nitecore T4K Flashlight while it worked it was a fantastic light. Some of the screws that held it together started to backing out of the housing. I had to purchase a really small torx driver in order to tighten the screws. The cover of the housing came off while I attempted to retighten. Once the light opened it was clear to me how cheaply these are made. There is circuit cable attaching the on/off button that came off from the main board that was nearly impossible for me to reattach. If you buy one of these, keep the screws tight and don't ever let it come apart. I could not fix the unit and it became useless. This is not up to par with the rest of the Nitecore product line. It's a cute (but bright) disposable keychain light, not worth the $80 they charge for it.

You did a fantastic job explaining! Ty!👏👏👏👏👏

Hey, I finally bought the Nitecore T4K and it was insanely bright and 10 seconds for me is just exceptional because I’m only living in town and unlike in forest areas that you will need a longer runtime for illumination. It is also brighter than my Nitecore TUP but the advantage of the TUP is that you can hold it for a long time until it’s too hot to handle and you can now step down to 200 lumens. Overall, these are nice products!

I want a light so bright it melts your eyes.

My man, you are excellent at these videos!

Your TIp2 is the most versatile light. I use it several times every day!

Wish they integrate a way to act as a flash camera smartphone combo as well. Bluetooth flash maybe?

Nice light but a little big for a keychain However great pocket light I have the lumintop edc 18 just bought the short body so it’ll be even smaller 2800 lumens and had 30 different settings , plus it’s programmable

Hi! Good video... but pocket light??? Idea is good, I’ll think TIP2 body, display, T4K power... HomeRun!!!

Just ordered one, Nitecore lights are second to none in quality.

It might be putting out 4000 lm but only for a few seconds before it steps down. Really it's a 200lm torch overclocked to get a very short burst of power. Personally I think it's misleading to call it a 4000lm when you can't even cycle to that setting and it can't run for any length of time at it.

Such a cool brand and tops all flash lights by a mile specially other tech, feels like a light saber to have

TAKE MY MONEY! Imma buy it someday!

I love you awesome mixed accent. Great Job Bro..

Nitecore has great designs but your flashlights drain battery when not in use. If I leave it in my pack for a few weeks. They'll die. I make my own circuit for your lights and don't have that problem. I'm pretty sure you guys can fix it. I mostly buy your lights for the shell.

As far as I know, the waterproof and dustproof performance of the product is IP54, but the C-type charging part is not blocked, but it is pierced, so I am worried that water may enter it This article may be inaccurate because it is translated using a translator

Very nice review and product

This thing is like a super power!

very quality review. greetings from 🇵🇭

Nitecore is one of my favorite brand especially in tactical pens

That is one high tech light.

I was waiting for him to point and illuminate the Moon.

this guy know what he do

I keep buying nitecore torches because they amazing and because of you lol 😆

Super great informative video! Please make more just like it! 👍🏼👍🏼👍🏼

Hi MJ - In terms of self defense/disorienting an adversary, what brightness of light is required - 500 lumens, 1000 lumens, 4000 lumens? I realize that this is a case where more may be better, but what would be the minimum effective in your opinion? Do you sell a plug cover for the USB-C port on the T4K? Even something to keep out pocket lint would be useful. Realizing that it will vary depending on ambient temperature, what is the expected mean cycle time for turbo mode to recover completely on the T4K? Given that the battery is not replaceable, what is the predicted # of average recharge cycles per battery/light and expected lifespan? Does frequent use of turbo mode shorten battery lifespan versus the other modes? For U.S. customers is there a price savings buying from Nitecore USA vs. Singapore? What about service/warranty issues - any difference between the two sources? I expect to make a big enough purchase that shipping will be free either way. Thanks for your excellent presentations! I learn from each one. ATB! John

Does it come with a lanyard?

Hi, I've been watching your videos, and my *only* use case is this: I need something small enough to carry in my pocket all the time on travels, but bright enough to be effective in self-defense, to be able to blind the attacker and run. So my questions: 1- You say T4K's light is not a narrow beam but more spanned, would it still be good for defense? And generally is it a good option for self-defense? I don't need to hit the attacker with it, just blind him enough so that I can vanish. 2- Is the TUP1000 good for the same use-case? or is 1000 Lumens too low for outdoor self-defense.

Could you talk about use while charging? Does this employ battery passthrough such that the battery and the LED receive separate current? Or is the battery simultaneously charging and discharging to power the light? I've heard the latter can dramatically reduce long-term battery capacity compared to true passthrough. Do the TIKI, TIP SE, and TINI 2 employ the same method for use while charging?

Great review. Though I'll probably stick with my TUP for now.

If there is a bracket to mount onto a bicycle will be great

Your a natural salesman . Its a lost art and my comment is meant as a complement .

It’s like a Tesla. From 0-60 less than 4 seconds. Then if you drive longer distance, it’s no good. I’d like to see an updated Tup, maybe Tup 2? 2K for about 5 minutes run time? That will be more useful than just showing off 4K for 10 seconds. But that’s just me.

I would love to see a side by side comparison of this and the Imalent LD70

Nice explanation. My question is why do lights always advertise XXXX Lumens and other company advertises XX Lumens. Somehow a more expensive respected company with less lumens seems to shine 3x more than a company that advertises “more” lumens. Why is that? What are the true lumens and why some companies lie?

I think with more customization for lighting level would be great. Like a 140 lumen option and a 350 option. Sometimes 200 isn't enough but 1k 2k and 4k are too much.

Thank you 🙏🏼

I have this light and it's pretty amazing.

Such an informative channel, you got yourself a new subscriber.

Thank you great video

Thanks for information

dang just came across you - killer explanations! awesome videos!

Good job on the presentation. I have nitecore light and charger. Excellent products! Highly recommended

Fantastic channel. Subscribed.

What’s the flexible USB-C cable stand? Can’t find it on Amazon. Thanks!

Brilliant!

Hey thank you, this was actually informative 🤙

Cool video thank you.

Loved the light when it came. My friends couldn't believe their eyes when I hit that 4K! Unfortunately after less than 90 days I can only get it to work on 1, 15 and 4K. When put on 65 and 200 it blinks then doesn't want to light up. Still works on 4k so that's cool, but doesn't look like it was built to last. How unfortunate

Nice video -thank you -keep them coming

Very good explanation. The best!

Hey we work in the pest control industry and love the t4k!! However we cannot use it in most food plants due to it not being intrinsically safe! Can we make these things airtight and bomb-proof??
