Fenix has a large line-up of tactical flashlights; each year, they add several new ones. Today, I am reviewing the TK22 Tac, which almost looks like an upgrade of the Fenix Tk22 v2.0 I reviewed back in 2019.

But if you know Fenix, they have several use cases in mind, even within a specific lineup. You can see that happening with the PD35, PD35 Tac, PD36R, and PD36 Tac. Now we have the TK22 and TK22 Tac. So, I don’t see this as a direct successor but as an additional light in the TK22 lineup. And truth needs to be said, this is considered a real tactical flashlight, unlike all the crappy flashlights found on eBay or Amazon that use the name Tactical to sound fancy.

Fenix is a pretty popular brand, even among non-flashoholics. They can be brought in many countries (if not all) around the world, so you should be able to get one at your local dealer.

Package quality.

The Tk22 Tac arrived in a pretty standard, retail-friendly package with an orange hangtag. And this is what you can expect to get:

• The flashlight: Fenix TK22 Tac
• Holster
• Pocket clip (pre-attached)
• 21700 battery with USB-C port
• USB-C charging cable
• O-ring
• Papers: warranty card, manual, flyer

Fenix isn’t some static company, adding an upgraded flashlight because of a new LED. No, they also try out new features, like the toggle/push switch used on the TK22 TAC. I first encountered this type on the TK11 TAC and quite liked the idea. You can single-handedly use the flashlight, so that’s a big pro. It’s relatively easy to toggle between Tactical mode and Duty mode with just a turn on the knob.

The main push-button switch isn’t your average clicky switch, but a 2-stage switch that doesn’t have a click sound. You can feel some resistance about halfway through the push, and if you press through that resistance, the light is turned on constantly.

Fenix calls it a military and duty flashlight, and the user interface fits that exactly.

The body has the typical Fenix reeding (and not the traditional knurling found with other brands), while the head has no texture/knurling except for some small flat parts. These flat parts help to keep the light from rolling off a table. And if these flat parts don’t help, the removable pocket clip will surely do. This makes the light relatively grippy without having any sharp edges or machining.

You can clip the TK22 TAC to your pockets with the attached clip, but you can also use the included holster if that’s more of your thing. Unfortunately, no lanyard is included, but the pocket clip has a small hole that you can use to attach a lanyard if you prefer that way of carrying it.

Fenix has been in business in business long enough to know that quality matters. And the TK22 TAC is built very well, just like all other tactical Fenix lights we reviewed.

Threads on the tail side came lightly lubricated and worked very smoothly. And that’s the only removable thing (besides the pocket clip) because everything is glued. That has its pros and cons, but from a large business’ perspective totally understandable. These are not built for flashlight nerds like us, flashoholics, to open up and play with, but rather for professionals who need to work with them daily and count on them.

I admit that I’m not a big fan of their anodization because although made of high quality, it doesn’t look as good as other brands (Jetbeam, for example).

If you’re on the lookout for a high-quality flashlight that you can count on, I would stop reading Amazon reviews and eBay listings. Unless you know the brands/flashlights for sale, most of them that are called tactical, aren’t really tactical. And although Fenix flashlights aren’t cheap, you can count on them.

And if they somehow break, you are probably covered by their Warranty policy.

Warranty? If you buy them from Fenix Lighting US:

All warranty repairs or replacements are at the sole discretion of the Fenix Lighting US Authorized Repair Center and we reserve the right to refuse a request.

While some bigger brands ignore sharing the name of type of LED, Fenix doesn’t. They openly admit the type of LED used in this model, namely the Luminus SFT70. This particular one is a cool white version.

The SFT70 is a 6V / 12V LED, so they need to boost the voltage in order to power it up.

The LED sits in a deep, smooth reflector, protected by a glass lens with AR coating. The bezel has some crenulation, but they aren’t sharp or anything.

I used the Opple Light Master III to measure the characteristics of the LED. I measured them in Low and in Turbo. Low mode was measured at a distance of about 70cm, and Turbo from about 2 meters. Remember that these are not exact numbers and should be taken as an ‘average’.

Low mode:

• CCT: 5651K
• CRI Ra: 64.2

Turbo mode

CCT: 6324K
CRI Ra: 70.2

It’s a little strange to see a difference of the Ra measurement, because 64 and 70 is quite a difference, but it’s enough to tell these are not high CRI emitters.

The beam isn’t very pretty to look at, and that’s not the reason for buying this flashlight anyway. Because of the smooth reflector, and the type of LED, you can see some artifacts in the beam.

Group 3: Fenix TK22 v2 vs Fenix TK22 TAC

The light features a rotary switch and a traditional push button switch. The rotary switch has 3 positions: Tactical Mode, Lockout, and Duty Mode. Duty Mode has 4 modes (plus a hidden Strobe), and Tactical Mode has a single Turbo mode, with the hidden strobe activated by pressing and holding the button for more than 1 second. 

The middle setting on the rotary switch is the lockout. If you lightly tap the switch, it works in momentary mode, but a firmer press activates continuous mode.

Modes:

DUTY MODE:

• Eco, Low, Medium, High.

TACTICAL MODE:

• Turbo, Strobe.

From OFF (Duty Mode):

• Press half and hold (1st stage): Momentary On in whatever mode it is
• Half pressing: change modes
• Full press/click (2nd stage): activates Eco, Low, Medium, or High
• Double click: N/A

From OFF (Tactical Mode):

• Press half and hold (1st stage): Momentary on
• Full press/click (2nd stage) short: Turbo
• Full press (2nd stage) long: strobe

From ON (Duty Mode):

• Tapping: change modes: Eco, Low, Medium, and High
• Press and hold for 1 sec+: Activates strobe

From ON (Tactical Mode):

• Press half and hold (1st stage): Momentary Turbo.
• Single full click (short): Turbo
• Single full click (long): Strobe

Mode memory:

• Yes, it has mode memory

Low voltage warning:

• Yes. The output will drop to a preset level until it reaches Eco Mode where the light blinks 3 times every 5 minutes until the light turns off. Please note that this only works when using Fenix-branded batteries!

Strobe/blinkies

• Yes, both are accessible in the Tactical and Duty menu

Lock-out mode: 

• Turn the rotary selector to Lockout Mode or unscrew the tailcap ⅛ turn to lock out.

PWM

• Yes. But not really visible

Fenix included an ARB-L21-5000U battery. This is a 21700-type USB-C rechargeable battery. This means that it’s too long for 99% of the battery chargers on the market, but the good thing is that you don’t need one because you can use the built-in charger. Fenix added a USB-C charging cable in the package..

It also has protection to prevent short circuits or overcharging / over-discharging.

The nipple on the positive side of the battery has a little hole in the center. You can see a tiny red light inside the hole while charging, turning blue when fully charged.

The charge speed I measured increased to about 1.4A, but it starts and finishes at a lower charge current.

18650 batteries won’t fit without a proper adapter. They will rattle and not make contact, and unprotected, flat-top 21700 batteries do not fit!!!

Lumen measurements

How Lumens are Measured: Understanding ANSI FL1 Standards How Lumens are Measured: Understanding ANSI FL1 Standards: The ANSI FL1 standards specify that output in lumens should be measured 30 seconds after turning on, as this is the standardized time for measuring brightness according to the industry standard. This is why we focus on this part in our measurements. The ANSI FL1 standards require an ambient temperature of 22 ± 3°C. We record the ambient the ambient temperature to identify potential reasons for any observed discrepancies.

All output numbers are relative to my homemade Integrating Sphere. It is set up with an Extech SDL400 Lux Meter for measurements, including a Kenko PRO1D ND-16 filter. The base measurement is done with a Convoy S2+ that has been tested at 255 lumens.

Tested with a Fenix 21700 ARB-L21-5000U

Mode	Specs	at turn on	30 sec	10min
Eco	30	32 lm	34 lm	–
Low	150	157 lm	156 lm	149 lm
Medium	350	365 lm	364 lm	360 lm
High	1000	995 lm	990 lm	954 lm
Turbo (Tactical)	2800	2742 lm	2234 lm	786 lm
Turbo at 3.8V	–	1936 lm	–	–

I also tested to see if the light would run in turbo mode when the battery was down to 3.8V, and it worked.

Battery Life: Runtime graphs

How Runtimes are Measured: Understanding ANSI FL1 Standards About ANSI FL1 runtime standards: The runtime is measured until the light drops to 10% of its initial output (30 seconds after turning on). This does not mean that the flashlight is not usable anymore. The last column shows how long the light actually works till it shuts off. If there is a + symbol, it means that the test was stopped at that particular point, but the light was actually still running. This happens on certain occasions, with certain drivers, firmware, or batteries.

The runtime test was done with the 50cm integrating sphere, including the Kenko Pro1D ND-16 filter and Extech SDL400 data logging Lux Meter.

Mode	Specified	Measured runtime (ANSI FL1)	Time till shut off
Eco	49h30min	not tested	not tested
Low	18h30min	29h56min	30h10min+
Med	8h10min	8h21min	11h21min
High	4h	3h00min	6h27min+
Turbo*	3h	2h42min	7h45min

*I let Turbo run till it turned off. After the ANSI FL1 runtime (at 2h42min, the light dropped to 135 lumens and stayed there for quite some time. At that point it’s wise to change batteries. BTW Turbo mode is only available in the Tactical mode group.

The runtimes don’t really match up with the specs. Turbo and High run shorter than the official ANSI FL1 runtime specs, while Medium and especially Low run much longer than specs. But they kept running for many more hours, as seen in the last column. Very good performance.

Peak beam intensity and beam distance measurements

About Peak beam intensity: Understanding ANSI FL1 Standards About peak beam intensity The calculated value of distance in meters at which the flashlight produces a light intensity of 0.25 lux. (0.25 lux is about the brightness of a full moon shining on an object). This means that the intensity has decreased so much, it becomes difficult to see darker objects, or objects that don’t reflect light. The columns ‘Meters’ and ‘Yards’ use rounded numbers.

Peak beam intensity and beam distance measurements

Measurements were taken indoors with a Hagner E4-X Lux Meter, at 5 meters, 30 seconds after turn on.

Mode	Specs	Candela measured	in meters	Distance in yards
Eco	760	1,025	64	70
Low	3,560	3,975	126	138
Med	8,850	11,425	214	234
High	24,800	31,000	352	385
Turbo	74,000 cd	72,250 cd	538 meters	588 yards
Turbo (at turn on)	74,000	89,250	597	653

My measurements were higher for all modes, except Turbo. Turbo (after 30 seconds) was just below spec.

If you use a mobile device, rotate your phone horizontally or open this link for a closer look.

The following graph focuses on the first 10 minutes after activation. If the details are unclear, access the interactive graph through this link for a closer look.

And the last comparison, we zoomed in to show the differences even better. For the first 60 minutes after activation. Not clear? Use this link for the interactive graph.

For the following beamshots, I used a Canon EOS 5D Mk2 and a 50mm lens. manual settings: ISO1600, 1/4sec , F4, 5000K. The shed is about 65 meters / 71 yards distant, and the reflective fence over 200 meters.

And the following comparisons you can make (these are right after turning on)

• Fenix TK22 TAC vs Olight Warrior 3
• Fenix TK22 TAC vs Olight Warrior X3
• Fenix TK22 TAC vs Nitecore MH25s

Please note that the following beamshots are mainly intended to showcase the beam pattern and beam quality, rather than overall performance. These images are typically taken directly after activation, and in different seasons or weather conditions, and therefore do not fully represent its overall performance. In few cases the camera settings are even different and therefore not meant for performance comparisons. For accurate performance metrics, such as output, beam distance, and runtimes, you need to look at the performance section of this review.
