Fenix TK22 1600 Lumen Tactical Flashlight & 21700 Battery


After the recent look at the Fenix LD30 Flashlight, Fenix contacted me and asked if I wanted to follow-up with their TK22 V2.0. This is also a 1600 lumen light, but it features a larger (21700 5000mAh) battery and a tighter beam that can reach out to an impressive 405 meters. It features a removable tail-cap that can work with remote pressure switches and it offers a bit better performance thanks to its increased size. Keep on reading and see how this compares to the LD30 we looked at previously.

First Look:

The Fenix TK22 is a 1600 lumen, 21700 flashlight that can also be powered from a 18650 battery using the included adapter. The TK22 has a IP68 waterproof rating, comes with two switches for power and mode functions. It is a fair bit larger than the LD30, as this unit comes in measuring 5.91 inches long and has a larger body diameter due to the larger 21700 battery. It has a much larger head as well. This houses the much larger parabolic reflector which gives it a tighter beam focus and consequently much greater range. It is rated at 405 meters with the LD30 rated at 205 meters. It is a bit larger but packs a lot more punch.



The TK22 comes with the main flashlight, ALF-18 Battery holder that allows you to use any 18650 battery, a holster, lanyard, spare clickly-switch cover, spare o-ring, user manual and warranty card. The review sample came with the very large 5000mAh ARB-L21-5000 battery from Fenix as well. This massive battery has no built-in charging port, but it makes up for that with as much capacity as many new laptops.

More Thoughts:

The TK22 doesn’t have a battery level indicator and only has four brightness settings in addition to the strobe/SOS modes. The controls are simple and work very well.


I never used a range finder to test the range of the TK22, but suffice to say, it’s a heck of a lot more focused and has longer range than the LD30.  It’s by far the brightest torch I’ve used and could probably cause vision damage if used inappropriately. 

The SST40 LED in this model is incredibly white as it has a clear glass lens that lets the LED blast unobstructed and unabated into the darkness. It’s impressive.




While the LD30 was a huge step up from other flashlights I’d previously used, the TK22 is equally more impressive than the LD30. It is priced about $20USD more than the LD30 and you must decide if you want to spend a bit more on a bulky, more powerful light, or prefer something that’s more pocketable and while impressive, is a bit dimmer. I’ve seen the TK22 here in Canada for $120 without a battery, and while that seems expensive, you won’t find a brighter, tougher, better light for that price here in the north.
It’s a little bulky for an EDC, but if you can manage it, you won’t be disappointed in the performance. My only caution is that it is a fair bit larger than the LD30 - which seems to be a pretty standard size. As it is larger, it may not work for everyone. If you do pick one up, you won’t be disappointed, however. It’s a beauty and a beast that is as bright as the sun.

Side by Side


The Fenix TK22 is even better than the LD30 in terms of brightness, but it is a bit bulkier as you can see. Either way, it's a solid performer and I'm happy to give it our Gold Award.
