The P23i flashlight is an i-Generation Tactical Flashlight that uses a Luminous SFT,–70 LED. With a maximum output of 3,000 lumens, it’s perfect for every profession. It’s capable of a maximum throw of 470m, plus a high beam intensity of up to 55,300cd, features two switches on the tail intentionally to enable the user instant and easy access to the STROBE mode. The STROBE mode helps in causing more robust and more intense, dizzying effects. Here is the detail instruction
This flashlight is interesting, the SFT70 led is slightly larger than an xhp35hi, but ensures more lumens… 6500k and 70cri??
The technical sheet seems excellent for this type of product.
Please can Nitecore go back to constant frequency strobes. They have many flashlights that would be good for light painting photography if it wasn’t for alternating frequency strobe. The last useful light was the P10 V2.
This is interesting. First xxx70 emitter for them (I think). Since it’s high CD - a thrower more or less, I’m wondering about beam pattern / spill? Nobody I know of provides off-axis candela not to mention a polar graph… so you have to look at beamshots (which atm don’t exist). I may just order one to find out…
Fenix has fielded a few lights with this LED already. I tried the TK20R V2 and found it to be excellent. The sst70 version is also nice, but green at low output and about 100 m less throw.
Yes, I have newish Fenix E-35 3,000 lm, and it is greenish at lower powers. I understand it is the nature of the emitter. I’m actually thinking of getting a TK16… maybe a 20. The 16 is shorter and is on sale now. Not sure if I trust Nitecore on beam pattern. The lower power Nitecores I have are fine, but looking at YouTube beamshots of their later lights (MH12x) I would not be happy with them. The Nitecore headlamps I have are very good, IMO.
Everyone is going at each other with these tactical lights. Fenix, Olight, Jetbeam, now Nitecore and recently Acebeam with the new P17 and P18. I think Acebeam takes this one honestly. They are always using the best LED bins.
Can’t go wrong with Acebeam anything. I’m looking forward to the P17 with xhp70.3 HI. The P18 is a little weird for a tactical light.
I’ll have to check Acebeam. Funny on the “tactical” … “tactical” clothing, guns, knives, flashlights, and I think food 
I’m a bit of an outlier… and dating myself. I well remember back in the 90s when a long MagLight was THE tactical light to have. (I had several). I now jump back into the fray about every 5 years or so, find out what’s new, what’s “best,” buy some stuff, then disappear again. If I stayed more active & “in the know” I’d probably end up spending too much money!
That P-17 looks amazing. I’ll have to check see if there are any reviews / beamshots. And if they give a “newbie” discount… since I’ve never bought from them!
Checked out the P-17. Nice, but can’t understand the 3 modes / programming even though I have the instruction manual. I’m reluctant to pay money for something I’m not sure I can get to work.
The tail switch reminds me of my older Klarus XT11GT with the duel tail switch. One touch strobe one touch turbo. I purchased the crazy Strike bezel as well that sticks out just over 3/4 of an inch. Nice looking Nitecore.
Klarus was probably the first flashlight manufacturer to implement this kind of switch into a 18650 light.
Fenix had implemented it a few years earlier on the LD40 and then the newer LD41 but waited years to design a 18650 light with a dual tail switch.
I think the first Fenix light was TK32 followed by the TK16.
Nitecore released the first version of the P10 and P20 around the same time.
They released many other lights with this type of switch over the years (P10GT, P20 V2, P10 V2, P22R, i4000R, P10i, P20i P10iX, P20iX, as well as some TM lights).
The P22R and i4000R were pretty interesting, with true lows (1 and 2 lumen respectively) and a hidden USB port, but were short-lived.
Fenix has been releasing several lights with the dual tail switch over the last couple of years: TK20R, TK16 V2, PD36R PRO. They are also supposed to be releasing a PD35R in 2023.
I find the Fenix UIs pretty high and dry though: usually just the old cycle-through UI with memory mode, no programming and no shortcuts.
I find some the Nitecore P series lights usually have a much better UI with programmable modes - even if most of them lack a true low.
Personally, I find Klarus is currently the only manufacturer offering lights with a dual tail switch that have a really good UI: a tactical mode with direct access to turbo and strobe as well as an outdoor mode with direct access to low and turbo.
