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

Product Information

It runs on AA sized batteries and includes a 800mAh 14500 protected Skilhunt branded battery. This battery can be charged inside the torch using the supplied magnetic charging cable. Unlike Olight, this magnetic charger will work with any 14500 battery. Additionally slightly shorter non-protected batteries also fit and even better you can use Alkaline and NiMH batteries, albeit with much reduced outputs. And you have to be careful not to try and charge either of these batteries with the magnetic charging cable. A red charging LED underneath the lid comes on when you insert the torch and turns green when the torch is fully charged. As we can see from the graph below, I did some tests on and off with the T4K in Turbo mode for about 10 minutes with the T4K fully charged at 4.20V. 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. Switching ON and OFF is done by the electronic switches on the side of the flashlight. There is momentary activation (MOMENTARY TURBO) using the MODE switch. Normal Operation

This unit is ridiculously bright when in Turbo mode, and it’s not surprising that Nitecore included a warning in its documentation about shining this light into someone’s eyes.It’s a little less convenient removing the battery to charge it, but you don’t have to worry about making sure any external ports are sealed. The Fenix PD25R comes with a USB-C to USB-A charging cable, spare o-rings, a lanyard, a user manual, and rather surprisingly a little mini pouch for your belt. So while not quite hitting 4000 (on my sphere), it’s within the margin of error I expect with not having professional equipment, and realistically there’s almost no visible difference between 3736 and 4000.

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. When turned to its maximum settings, the flashlight’s beam throw is 209 meters and its luminosity is 4,000 lumens. Four powerful LEDs provide the light, each with its own smooth reflector to maximize beam throw and intensity. The Wurkkos TS10 comes in a plain box with a lanyard, spare o-rings and a user manual. This is an AA style torch but will only take 3.6V Li-ion 14500s – it needs at least 3V and won’t work with standard 1.5V AA Alkaline or NiMH batteries unfortunately. LED. Ті, хто знайомий з таким пристроєм, можуть дати про нього лише позитивні відгуки. Тому всілякі технології і сучасні матеріали, які втілені в ньому, це не просто маркетингові дослідження, а дійсно практичні іфункціональнірішення професійного виробника.

What’s in the box?

All of the beamshots taken below are done so with the following camera settings (ULTRA-LOW: 2.5 sec, F3.5, ISO100, 5000K WB, LOW: 1 sec, F3.5, ISO100, 5000K WB, MID: 0.5 sec, F3.5, ISO100, 5000K WB, HIGH: 1/5 sec, F3.5, ISO100, 5000K WB, and TURBO: 1/25 sec, F3.5, ISO100, 5000K WB). I measured the colour temperature as a cool 6507K but with a very neutral tint and a decent CRI of 70.

And an arguably more useful torch for day to day jobs around the house, working on the car and DIY tasks – especially in the winter months is a head torch. I also use one for running sometimes three times a week at the moment with these short days. I’ve already started collecting the best options I can find for another roundup – that video and article should be out soon! Nitecore T4K features the ATR (Advanced Temperature Regulation) module, which adjusts its output power by adapting to the surrounding environment, maintaining optimal performance. It’s a bit on the large side for EDC suitability, but it’s definitely one of the best-performing EDC lights on the market. I also tested the Thrunite T2 which runs off the larger 21700 battery but is still very compact. Thrunite quote a 3757 lumen output although I measured a fair bit lower at just under 3000 lumens, still very powerful for its size. Turbo output from Thrunite T2The 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 Olight Warrior Mini 3 (new model): UK: https://www.olightstore.uk/s/DS85DL US: https://www.olightstore.com/s/6QEQ5S 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. With the torch off, by pressing the “MODE” key, the display shows for a few seconds the level and user mode set and the current voltage with the drawing of the battery. My first article and video in this series covered even smaller keychain torches. And also introduced a few technical terms – so it’s worth a read / watch if anything I cover in this video needs further explanation.
