The strobe is more effective than the Klarus. USB charging is pretty fast so not sweating the dumb battery. Lot of these new lights lately are pushing too hard and get hot quick. P20i is my current favorite tac light. In my pocket right now is my trusty Fenix UC35 that's a few years old. Old Skool light you don't have to spray with liquid nitrogen after 1 min.

Muito bom o seu vídeo , me esclareceu várias dúvidas ...

Thanks for the video, nice review. I think Klarus really nailed it with the UI and their Outdoor mode.

Refer to the manual. You can actually reprogram the light from "tactical mode" into "daily mode". In the latter it will start on whatever setting last used. This makes a little more sense because its not a very good tactical light. I base that opinion around actually using it in a tactical application during the course of a year: I work in private security and law enforcement. Every time I've made a somewhat violent arrest the light would fall out of the flimsy plastic holster. The button would also often catch on my my vest and get turned on. Since I replaced the holster for a nitecore cordura one this almost started a fire in my car as the cordura melted. I dropped the light from a fairly low height onto concrete. It landed on its side but the lens still shattered. I doubt this would ever survive being used as glassbreaker or striking tool. This might have some tactical features but its not a tool a picky professional should concider using. I would recommend looking at the Olight Warrior 3s instead. Similiar price and features, slightly more compact, a little brighter and alot more durable. I did replace the lense because overall I like the light alot and I still get alot of use out of in in civilian life.

How does it compare to the new klarus e3? Would be great if u could review it too!

Great review. I got the newer P20i UV. Not because it has UV light, but because it has both daily mode and tactical mode.

Looking to pick up the P20i for edc. All of the potential issues, mostly seem like 'features' to me ; - ). I had the Klarus XT and lost it in the woods. 2300 Lumens is a lot of fun, but I'm now seeking a tighter beam and hoping that holster works as good as it looks. That said, I would definitely by the Klarus XT again, and would possibly be a better choice for normal people. Great review!

I got the 4K ...how do they compare ? The 4K is really floody but not much throw

Is what it is - Designed for tactical, as you say. I wouldn't want to be a LEO and have to turn on my light in a hurry, only to have it come on at 15 lumens, etc. Simple & effective use and design. Pretty much foolproof, which is what you want, under pressure. Topped mine off with the Nitecore TSL10i signal light tail cap, which is certainly worth a look. 👍

Sry for my bad English, how long it hold the 1800 lumen? After 2 min it step down? Greetings

can you activate 1800 power with "mode" button when mid light on? I know you can do this on P20ix model.

I just picked up the Klarus XT21C over this Nitecore P20i, I feel like I made the right choice. P20i will probably end up in my car's glove box.

Just snagged one with a discount! Can't wait

Thanks for this review, i wonder if this flashlight able to take olight battery 21700 and function with it

Hi, Is it possible to turn on the flashlight without making a clicking noise? Because in tactical training this noise can be fatal and deliver the operator's location.

Great review! Does this light have a tailcap that can be unscrewed slightly to lock out the light?

I like it but yes the main button design is questionable. Thanks for the review !

Excellent review, well done 👏

It can use CR123 at lower 1100 lumens, and vape batteries I think

How have klarus lights served you? I had a klarus a while back and it crapped out on me :(

Nice light. I not a fan of the protruding button. Otherwise I like it.

i had to remove my headphones a couple times as i thought it was my kids playing in the background. nice review! i added this to my amazon cart.

The p22r was so much better. Idk why they discontinued it. 😞

👍& SuBB!! Datz wat i did..😁😊😎!! Nice bro..

It’s perfect for law enforcement and tactical use. It’s a complete nuisance for the average user. Unless you’re always outdoors in a wide open area, you’re going to blind yourself whenever you turn the light on since it comes on at full turbo mode. I made the mistake of buying this light thinking it would be useful for my job as a repairman

Great video.

No pocket clip?!

I love the features of this flashlight (even without a really low lumens mode), but being forced to use a special Nitecore battery is probably a deal-breaker for me. If I'm out somewhere and the battery goes dead, I want the ability to pop in one of my other non-Nitecore 21700 batteries at least temporarily. I think this flashlight will work with CR-123's so I don't see why it won't work with other 21700 batteries as long as you don't try to charge them in the flashlight.

I just paid 70 bucks on eBay for this I am a current rent a cop 😂 this works awesome very powerful

the propretary batt. makes it a nono for me.

Not bad for 5 bucks.

Don’t forget …. Made in China
