Nitecore T4K Rechargeable Torch 4000 Lumen Turbo Super Bright Small Flashlight, Protective Case Included

Product Information

With the torch off pressing the mode button shows the battery level of the torch with a graphical icon and its voltage. It’s fully charged at 4.2V. It’s actually in Nitecore’s keychain torch lineup – I looked at the two smaller torches in this lineup in my last article– the Tiki and Tini 2. It’s a bit of a stretch calling this a keychain torch, but it does come with a keychain attachment, unlike any other torch I’m looking at today. Like the thought of many, mine too is that of an intermediate level between the 4000 lumens turbo and the high 200 lumens level. Despite everything with 200 lumens I can see well the walk up to about ten meters.

The first 3 ignitions were consecutive while, subsequently, the other 3 after about 10 seconds from each other. After these six close ignitions for the others, about 50 or 60 seconds were allowed to switch on. At the end of the test, the display of the TINI2 showed 3.90V.Nitecore T4K features the ATR (Advanced Temperature Regulation) module, which adjusts its output power by adapting to the surrounding environment, maintaining optimal performance.

Today I’m taking a look at the Nitecore T4K, the latest in the Nitecore keychain light series. This is the successor to the Nitecore TUP, which has always been a light of interest for me. A small light with an OLED screen? Ridiculous! The primary change is to increase the number of emitters from one to four, so this should be quite a hotrod. I measured an unbelievable 4855 lumens at turn on, 4659 lumens after 10 seconds – just, and then a dramatic drop off to 232 lumens for the remainder of my measurements.

In turbo I measured 1785 lumens at turn on, 1744 lumens after 10 seconds, 1673 lumens after 30 seconds and it dropped sharply to 520 lumens after 80 seconds. It held this constantly for the remainder of the test. The T1S uses a Luminus SST-40 LED behind a TIR lens and has pretty good throw for a tiny torch with a noticeable hotspot – around 184 metres or 8460 candela in turbo mode. Like the Fenix E18R V2.0 these modes are very well regulated and my measurements confirmed Olight’s specs with constant outputs up to the 300 lumen high mode. Turbo turned on at an impressive 1310 lumens, was still at 1299 lumens after 10 seconds, 1282 lumens at 30 seconds, and pretty much as spec’d dropped to 290 lumens after 90 seconds where it remained at 5 and 10 minutes and for as long as I measured its output. The Acebeam E70 Mini comes with a short USB-C to USB-A cable, a lanyard, spare o-rings and a user manual. The OLED display is a fantastic feature because you’ll never be left wondering how much time is left before the battery dies. For each brightness level, the display shows a real-time countdown of the minutes left on that level. Brightness modes and max runtimes

Final thoughts

It comes with everything to get you started, including a 21700 battery with 5,000mAh capacity. It also includes a USB-C cable, so you can charge the battery inside the flashlight. No need to get a separate battery charger. Nitecore T4K has 5 brightness levels available with direct access to TURBO and ULTRALOW, it also has 2 user modes, DEMO Mode and DAILY Mode. This is a very compact 18650 torch with up to 4000 lumens that runs Anduril 2 and also has multi-coloured auxiliary LEDs. Probably the most impressive feature of this torch for its size is its beam profile. It has 250 metres of throw or 15530 candela of intensity. But even with the tight hotspot from that deep smooth reflector, there’s still enough spill for it to be useful as an EDC torch.

For this light, the spill, corona and hotspot is somewhat predictable due to the TIR optics. Surprisingly, the LEDs are not covered under the TIR (Total Internal Reflection) optics. With the LEDs used, the beam is suited for recognizing items in the near to mid-range distance. As the light is IP54 rated only, the light was subjected to being left under room temperature running water whilst running on HIGH. The switch has a battery indicator light that comes on with a single press when the torch is off, or for a few seconds when you turn the torch on. Solid green and the torch has over 85% charge, flashing green 50-85%, red 25-50% and flashing red if it’s less than 25% charge remaining. This is handy but only works with the supplied Fenix battery – the ARB-L16-700P. And some longer batteries with protection circuits won’t fit, for example this Keeppower one. But I did find this Lumintop 14500 with built-in USB-C charging fits – I would have preferred Wurkkos included a battery like this with the torch – it would be far more convenient for newcomers to these higher performance torches. The torch weighs just 51.9g (1.83 oz).

Four thousand lumens in a flashlight this small is pretty insane. I already own several EDC flashlights, including Maratac AAs and AAAs, ReyLight Pineapples, an Olight i3T and Olight i5T, and even a 2800-lumen Anduril-powered Lumintop FW3T. The latter of which was my brightest EDC flashlight—until the T4K came along. The Nichia 519A LED sits inside a slightly mottled reflector and there is a noticeable hotspot, but with a fairly low output I still only measured 82 metres of throw with 1682 candela of intensity. While that may initially seem like a bad thing, trust me, it’s not. Without this feature, you could seriously burn yourself if this light was left on accidentally. DMM: UNI-T UT139C and UNI-T UT210E – 16AWG wire is used directly into the 139C via some banana plugs, and 8AWG wire in a loop for the UNI-T. The DMM I use depends on how high the expected current will be – I use the 139C for <10A, and the 210E for >10A.
