After been immensely impressed and blown away with the Nitecore TM28, it got me looking for a what I call "fit in a trouser pocket torch" and I started looking at what Nitecore had to offer. I narrowed it down to two models. The P20iX and the P23i. After looking at the specs for them both and also watching many videos online showing them both, I decided that the P23i would be the better option for my usage (which is night time nature spotting down my local river and fields). The P20iX is more of a wider flood light, whereas the P23i has a more focused and further reaching beam and that is despite the P23i having 1000 lumens less than the P20iX, but the P23i has nearly five times more candela and 250 metres more beam distance than the P20iX. I find that for me personally, I find the P23i has the perfect amount of width to its flood to more than adequately light the full width of my path and then some, but gives me an amazing amount of reach with the beam (which is exactly what my usage prefers). This amazing little torch lights up the opposite riverbank (some 100 feet away) like daylight, and the field and edge of the wood (around 150 feet away) very clearly and I can see the animals in that area very clearly. The UI is very easy on the P23i, with daily mode and tactical mode which can be switched by holding the mode button down, loosing the tail cap slightly and the main white LED will flash to indicate the mode has been switched. Personally I run mostly in tactical mode as I like access to 3000 lumens/turbo without needing to hold the mode switch in with my thumb (which I find can be a little awkward with thick gloves on). The only criticism I have is that in tactical mode you loose the 1500 lumens option, which can be a good middle ground between the 800 lumens and the 3000 lumens option, but saying that, I mostly find that when I need anything brighter than the 800 lumens (which is the level I leave the torch on when I am just lighting the area I am walking along) it is to light something up that is further away, and I then just jump right on to 3000 lumens/turbo. But the switching of the modes is very quick and easy, and I find that sometimes I will switch between the two at different points when I'm out and about. It really is a good inclusion by Nitecore to have these two modes and will no doubt make tactical users happy as they can set the mode on tactical when they first receive the P23i and then just leave it on this. The light outputs I find are well spaced out and on daily mode there are 50, 250, 800, 1500 lumens and turbo/3000 lumens is accessed by holding in the mode button, releasing it will put you back on the brightness level you had it set on before pressing the mode button. You also have a memory option on daily mode, for example setting the P23i on 800 lumens, and if you then switch the torch off, the next time you switch it on, the torch will remember and come on, on 800 lumens. On tactical mode there is no memory mode, and when switched on, the torch will always turn on, on 3000 lumen, but a quick press of the mode button will put you down on to 800 lumens (which I find way more than adequate for lighting your way along a pitch black river or woodland footpath). Either way, it is very quick and easy to switch back and forth between the daily mode and the tactical modes depending on what your usage dictates on that given day. The battery life is very impressive from the i Series 21700 battery and I am usually nearly finishing my walk when the P23i blue power LED starts to flash rapidly (indicative of less than 10 percent remaining). I did purchase an extra battery at the time I purchased this for the times when I need it for that extra bit of time I am out, but please be aware that the P23i (and some of their other models) do not work with standard 21700 batteries, they take a proprietary Nitecore battery, so please bear this in mind if you want to purchase additional batteries. I did read t


The Nitecore P23i flashlight has a maximum output of 3000 lumens from the Luminus SFT-70 LED and is powered by an included NL2150HPi iSeries 21700 battery. The light is rechargeable via a USB-C port at the head of the light and comes with a USB charging cable.

The torch has Nitecore's 2nd generation Strobe Ready technology with instant access to strobe mode with an inset mode switch to avoid accidental activation. The output has a randomly changing frequency between 16Hz and 20Hz, for emergency use. The tactical U-shaped tail cap also offers tail stand capability and can be used with a wrist lanyard (included).

The P23i has a range of tactical features including a strike bezel for emergency use, impact resistance up to 2 meters, a dedicated tactical mode and one-hand operation. The flashlight is compatible with a variety of accessories including the Nitecore RSW2i remote switch, TSL10i signal light, gun mounts and 32mm filters, diffusers and traffic wands (all sold separately).

In addition to the tactical mode which offers four brightness levels and strobe mode, daily mode can be used which provides the full five brightness levels ranging from 50 to 3000 lumens, plus strobe.
