Nitecore P20iX Review (4000 Lumens, 4 LED, 21700, USB-C)

Today I have a new Quad LED light from Nitecore with the P20iX that produces up to 4000 lumens on a 21700 battery and it features onboard USB-C charging with Tactical and Daily modes. Thanks to Nitecore Store for sending this to me to look at and review.

Packaging & Accessories

Packaging is a step up, with a nice high quality box full of information. Inside the light is packed in foam with all the accessories underneath. It reminds me a bit of how Olight does theirs. Accessories include a branded lanyard, Extra Oring, USB-A to C Charging cable, Pocket clip, CR123A battery adapter, hard plastic belt holster and a Nitecore specific 5000mAh 21700 battery.



Machining on the aluminum light is good here, and the anodizing is high quality. The tail cap has a large off center mechanical on/off button that’s covered with a textured silicone boot. It stands proud making the light unable to tail stand. Your mode switch is a flat, textured area. This is flush, but protected by the outer rim of the tail cap. For me this was harder to find in the dark and hard to actuate with gloves on. 

The body has some tame knurling on it, the pocket clip attaches near basically the middle of the light in either direction. The head does not separate from the body. On the head you have a large antiroll ring to keep the light in place on it’s side. You do have a blue LED that’s built into the side of the light that’s used as a charging indicator, similar to the MH11 I reviewed earlier this year.  The charging port has a large silicone cover and it fits tightly. 

At the front the light has a short bezel that doesn’t stand out from the lens very far, it has 3 protruding areas each with a small ceramic balls in them, I presume for striking glass that law enforcement may use. I believe the bezel is a little different material due to it’s slightly different finish. The lens is glass, and underneath there is a custom quad silver reflective optic for the 4 leds. 


Size & Weight

I measured the length of the light at 140mm. Minimum width on the body at 25.4mm, maximum diameter on the head at 32mm. Weight with the included battery in the light and no other accessories is 191.7g. The light is IPX68 water rated and drop rated to 2M. 



The P20iX has a couple of retention options that come in the package. First is the lanyard which is primarily slip fit over the light or attached to the clip. The clip which is a press fit is fit down pretty low, which leaves a lot of the tail or the head of the light sticking up out of the pocket. This is disappointing to me personally. That said the plastic belt holster that the light comes with does a pretty good job if you want to carry the light on your belt or on a mole vest. The light clips in with the front bezel facing down. 


LED & Beam

THe light has 4 Cree XP-L2 V6 Led’s in cool white with a maximum output of 4000 lumens. The tint here is cool white, likely around 6000k or a bit higher. The beam is somewhat compromised in this quad. The hot spot is pretty round but it’s not a smooth transition in the spill and you do get some Cree Rainbow. The very outer edges are a bit rough. That said it’s hard to nice in real world use at distance. 


Heat and Runtime

For my Heat and runtime I ran the light with the included 21700 battery. The light will run on 2x CR123 batteries in the included adapter if you wish but you generally get less output and for a shorter time. With the 21700 on turbo the light lasted only 30 second before step down. This was disappointing especially since the heat during this time at least measured externally didn’t amount to much. Step Down was pretty significant as you can see from the graph. As the light continued to run heat pretty quickly increased though up to about 55C, at about 21 minutes. Thermals eventually regulated at about 25C for the duration of the runtime. The light went into it’s lowest mode after about 3 hours of runtime where it continued for another 2hr and 20 minutes for a total runtime of 5:20:00.

I did another runtime graph with comparing runtimes of the 4 highest output modes, Turbo, Highest, High and Medium. The 3 highest don’t have a ton of overall impact on output. Medium ran for considerably longer, a solid 8 hours without stepdown. 



The P20iX has 2 modes, a Daily mode which it ships in with 5 individual modes, and then a Tactical mode with 4 individual modes. To switch between them, you turn the light on, press and hold the mode button on the tail and unscrew the light. It will flash Once for Daily, or twice for tactical and then you screw the light back together for it to be remembered.


Daily mode is where I am using the light most. In this mode the light starts in the lowest output and goes up with each press of the mode button. It has memory so you can shut the light off and when it comes back on it will be in the previously used mode. This mode has outputs of 2,50,300,850,1700 lumens, and then to get turbo (4000 lumens) you hold the mode button in and it works in a momentary manner. Double click this mode button to go to strobe in momentary. 


Tactical mode is similar but it goes from highest output including turbo down, and only has the 4 brightest modes.



The light features a USB-C port on the side covered by a tightly fitting silicone rubber cover. I used the included 5000mAh 21700 battery to run my charging tests and found total charge time took 3hr and 54 min. Max charge rate I saw was 2A. The light will charge via USB-C PD without issue. While charging the battery in the light, it’s not possible to use the light at the same time. The LED on the side will blink when charging and go solid when charged. When a battery is inserted it will also blink the voltage. 


The included battery looks to be custom with a negative terminal on the positive end. It’s a long protected battery with a shallow button top. It fits in my Vapcell S4 Plus charger and works just fine there. Due to that length I wasn’t able to find another battery I had that fit this light



This is a pretty nice high power flashlight from Nitecore. I like that it has a pretty practical daily mode, and that it’s not all tactical. It’s an interesting choice to have Turbo be only in momentary in daily too. I do wish Turbo had more runtime before step down though.


The clip on belt attachment here works well, and I suspect that or in a bag is how most would carry this light. For me the pocket clip is super impractical due to it being so far down the light, and that’s a disappointment. 


I wish the battery was more universal, but this semi proprietary format with the protected batteries and positive and negative terminals on on side of the light seems to be the way most manufactures are going with their 21700 light that have onboard charging. It’s a disappointing industry trend in many enthusiasts minds. To be clear this is an industry thing, not just Nitecore. 

Overall this is a solid light for general purpose and has some nice tactical features without being 100% tactical. I can see this being a good option for many if you don’t mind the cool white LED’s or short turbo runtime. 

Olight Odin Dedicated Weapon Light Review (2000 Lumen, 21700, XHP 35.2 LED)

The Olight Odin is Olights first purpose built long gun flashlight. It’s using a Scout mount, has a pressure pad and is capable of 2000 lumens. There have been a fair bit of sponsored Odin reviews, I strive to be different here and tell you how I see it. Thanks to Skyben for sending it to me let’s take a look and get to the review.

Packaging & Accessories

Olight once again does a very nice job here on packaging. It’s very appleske with a white magnetic fold out box and a full color photo on the front with specs on the back. On t he inside everything is packaged very nice inside little boxes, etc. Opening the front cover you have the quickstart guide along with the light and all the accessories. There are quite a few accessories with this light including the light itself and the 4 direction mount. You also get the 5000mAh 21700 proprietary battery, the MCC2A magnetic charger cable, and the new locking pressure switch. Lastly you get a few small zip ties to help mount the pressure switch, a small allan key, and a few extra screws and manual.



The Olight Odin is made from aluminium and hard anodized in a fairly glossy black. Starting at the tail cap, you have a very similar recharging point that was on the Olight Warrior X Pro, with the longer lugs to help you find the tail switch with gloves. It’s a two stage switch with a half press being momentary and full press locking on the light. Around the rear button is another ring and what looks like a space for an o’ring this is for the included pressure switch to lock on to the light which I will explain later. On the sides of the tail you have some tear drop areas milled in place for grip and style. Inside there is a large spring loaded brass contact. 

Threads are anodized, square cut and robust. It does take several turns to get them off. This is one of the few Olights where the positive terminal of the battery faces the head. The body tube is smooth except for the Scout mount. That’s fine, remember this isn’t an EDC light or designed to be handheld, it’s designed to be mounted primarily. 

The head you can tell was milled as one piece but it’s glued on to the tail and is non removable. It has a little larger ring which I assume is to help with thermal for the electronics. Styling wise you have two milled away tear drops, about the size of an endmill. At the front there is a black bezel with small almost saw tooth shaped crenulations. The edges are reasonably sharp. The lens is glass (Good for cleaning powder residue off) and underneath that is a TIR optic. 


This light uses the “Scout” mounting system that Surefire pioneered with the scout series of lights. It provides a 2 post mount thats about 7.75mm off the body of the light. It’s an extra piece that’s screwed to the light with 2 small hex head cap screws with locking compound on them. When I backed the screws out with a 1.5mm Hex key.

Olight included their locking mount that is designed to fit onto a standard picatinny rail. It can mount on the left or the right, and face forward or backward. It utilizes two hex head bolts and comes with the appropriately sized hex allan key. I would recommend once you get it to where you like it, to put some blue locktite on these screws, to make sure nothing backs off during use. This mount has 2 positions on where you can mount the light either on what I will call the bottom or the side. In addition to this light can mount either direction.This mount also locks once the light is in place to help secure it. Lastly the light does have threaded screw holes in it so you can use other 3rd party mounts like my favorite offset mount by Arisaka Defense. You may have to get a little creative with these in the order you mount them to tighten down all the screws depending on what your mounting it on. The big thing here is you have a lot of options.

The pressure switch is an evolution of what we saw on the M2R and Warrior series of lights. It’s designed to go on a picatinny rail as well and is rubber so it can slide on top and to secure you can use the included zip ties. The big difference here is that the end that attaches to the light has a locking mechanism. Simply push the ring forward to engage 4 small detent balls to grip onto the light, pull this ring back to unlock. It’s pretty secure for normal use and won’t break free under normal conditions. I did see a few posts in the Olight Facebook group where people had the lock come loose during extreme combat type situations so your luck might very. I would recommend disconnecting the pressure switch during transport in a bag to prevent the light from coming on accidentally. Cable length on the pressure switch is 165mm.

Size and Weight

I measured the overall length at 136.6mm, maximum diameter on the light (not including the mount) is 29mm, minimum diameter is 24.16mm. Weight with the battery was 174.1g, adding the pressure switch it’s 222.3g. 

LED & Beam

Olight has recently gotten into the nasty habit of not defining the LED they are using on some lights, and the Odin is one of them. With the TIR optic in place you can’t see the LED either. What I can tell you is it’s a fairly neutral white tint at the Turbo setting and in lower modes it’s a bit warm.. The beam is almost all throw with the focus in the center. There is just a very slight spill and there are a few artifacts here, which I think are the edges of the bezel showing. This is perfect for it’s intended use as a weapon mounted light where you want a tight focus. 

Heat & Runtime

The Odin produces upto 2000 lumens on turbo and this lasts 2 minutes before it steps down to 52% relative output. I saw maximum heat at 60C at 2:40 of runtime. Normally I would say this is too hot to hold but since this light is designed to be placed near the muzzle end of a hot firearm it’s not really an issue. We saw one more step down at the 12 minute markand the light ran at a fading 42% output for 2 hours. At the end it had one more step down before stopping right at 3 hours of runtime. I would have wished to see Turbo last longer here but suspect the time is thermally regulated as we can see the temps heat up some after cooling off initially. Overall runtime is the best out of a 1” weapon light that I have tested.


The UI here is pretty simple. On the light itself, the rear button has a half press which gives you the lower lumen mode, and a full press gives you the full 2000 lumens. If you press and hold in either mode the light is in momentary. If you do a quick press in either mode the light stays on. When the pressure switch is connected you only have the full 2000 lumens but the same press and hold gives you momentary and quick press gives you constant light. There is no strobe mode on this light. 


Recharging & Power

The Odin uses Olights Proprietary 21700 5000mAh battery which is required for this light. It’s one of the only recent Olights I can remember where the positive terminal goes in facing the head. Proprietary batteries are one of the things I dislike the most. This probably won’t be something you swap out a lot but if you want extra power be sure to buy one and keep properly stored in your kit. Olights MCC3 charging system here is a winner because it’s super easy to recharge and leave the light mounted on your weapon. It’s red when charging and green when charged, and this version charges up to 2A. Total charging time here was 2 hours and 7 minutes which seems pretty quick.


  • Use of the Scout mount meaning you have tons of mounting options to fit your application.
  • Complete Kit with a decent mount.
  • Good Beam for the purpose.


  • Only is compatible with 21700 batteries, CR123A’s are not an option if your out in the field and need more light after several hours. 
  • Some possible durability issues with the locking pressure mount system.
  • LED used is unspecified but is Neutral White.



For me this is going to be the light I plan on leaving on my 16” build. The way I have it configured now it’s easy enough to remove if I want to, but I feel pretty confident in it’s ability to perform to leave it. I may end up picking up an offset Arisaka mount to get it a little closer to the hand guard. 


Overall I think this is a good light for most citizens and hunters. Before I would trust my life to it in a police or military role I would want to do more durability testing. With the current pandemic and ammo shortage of 2020, I didn’t put that many rounds through my AR during range testing but what I did shoot the light held up without issues.
