Switches of the Fenix TK16 V2.0 Tactical Flashlight 

The round tail switch is the tactical switch for instant activation. 


The oval tail switch is the functional switch for output selection and instant strobe. 



Tap the tactical switch to silently and momentarily turn on the light, release the light will go out. 


Fully press the tactical switch to constantly turn on the light, press again the light will go out. 


Output Selection 

With the light switched on, single click the functional switch to cycle through Eco→Low→Med→High→Turbo. 



With the light switched on, press and hold the functional switch for 0.5 seconds to enter strobe, click the functional switch once again to turn back to the general mode. 


With the light switched off, press the functional switch to enter strobe, release the light will go out. 


Intelligent Memory Circuit 

The light memorizes the last selected output excluding strobe. When turned on again the previously used output of general mode will be recalled. 


Intelligent Overheat Protection 

The light will accumulate a lot of heat when used on Turbo output levels for extended periods. When the light reaches a temperature of 60°C or above, the light will automatically step down a few lumens to reduce the temperature. When the temperature drops below 60°C, it will then allow the user for the reselection of Turbo mode. 


Low-voltage Warning 

When the voltage level drops below the preset level, the flashlight is programmed to downshift to a lower brightness level until Eco output is reached. When this happens in Eco output mode, the light blinks 3 times every 5 minutes to remind you to timely recharge or replace the battery. 



Remove the battery from the TK16 V2.0 and plug the included charging cord into the port on the battery, with the other end plugged into a USB wall brick. 


Usage and Maintenance of the Fenix TK16 V2.0 Tactical Flashlight 

  • Disassembling the sealed head can cause damage to the light and will void the warranty.
  • Fenix recommends using an excellent quality battery.
  • If the light will not be used for an extended period, remove the battery, or the light could be damaged by electrolyte leakage or battery explosion.
  • Unscrew the light tail or take out the battery to prevent accidental activation during storage or transportation.
  • Long-term use can result in O-ring wear. To maintain a proper water seal, replace the ring with an approved spare.
  • Periodic cleaning of the battery contacts improves the light's performance as dirty contacts may cause the light to flicker, shine intermittently or even fail to illuminate for the following reasons:
    A: The battery needs replacing. 
    Solution: Replace battery (Ensure battery is inserted according to the manufacturer’s specifications).
    B: The threads, PCB board contact or other contacts are dirty. 
    Solution: Clean the contact points with a cotton swab soaked in rubbing alcohol.
    C: Use incompatible 21700 battery or the first-generation Fenix ARB-L21-5000 battery. 
    Solution: Use the designated Fenix ARB-L21-5000U, or Fenix ARB-L21-4000P battery.

If the above methods don't work, please contact your authorized distributor. 



  • This flashlight is a high-intensity lighting device capable of causing eye damage to the user or others. Avoid shining the flashlight directly into anyone's eyes.
  • This flashlight will accumulate a lot of heat when used for extended periods, resulting in high temperature of the flashlight shell. Pay attention to safe use to avoid scalding.
  • All information provided in this manual is subject to change without prior notice.

Q1. What are the key features and benefits of TK16 V2.0?

A:  1. Advanced Pulse-Frequency Transmission System (APF)

2. Instant activation and strobe with the dual tactical tail switches.

3. Stainless steel strike bezel with inlaid tungsten steel breaking tips.

4. Toughened ultra-clear glass lens with an anti-reflective coating.


Q2. What kind of LED is used in TK16 V2.0? And what are the beam angles?

A: LED: Luminus SST70 LED

Beam angles: spot beam angle - 11°, spill beam angle - 65°.


Q3. Does TK16 V2.0 have overheated protection?

A: Yes. The light will accumulate a lot of heat when used on Turbo output level for extended periods. When the light reaches a temperature of 60°C or above, the light will automatically step down a few lumens to reduce the temperature. When the temperature drops below 60°C, it will then allow the user for the reselection of Turbo mode.


Q4. What battery does the TK16 V2.0 support?

A: It supports the designated Fenix ARB-L21-5000U, or Fenix ARB-L21-4000P battery.


Q5.  Can I bring the TK16 V2.0 on a plane?

A.  Apparently it seems to depend on the TSA Agent/Airport.  While our employees have not encountered an issue, we have received a report of TSA requiring the light be in checked bags due to the glass breaking tips.    As such, we highly recommend that you place the TK16 V2.0 into checked bags as a precaution in the event you encounter a TSA agent that will not allow it on the plane.   We would hate to have you lose the light to TSA. 


Q6.  What is the APF?

A:The APF (Advanced Pulse-Frequency Transmission System) was developed by the Fenix ​​laboratory, a major technology breakthrough in flashlight industry, allowing the tactical flashlight achieve a higher level of performance:

1. Takes light to the extreme. Traditional forward switches are limited by current, and it is difficult to achieve brightness above 2000 lumens. In the age of 21700 batteries gradually expanding, 3100 lumens tactical flashlights are almost impossible, whereas a flashlight using APF technology can reach these higher lumen levels.

2. Makes the functional tail cap simpler. Traditional multi-function tail caps need to achieve functionality through the double-layer body or additional channels. A flashlight using APF technology offers a strong reliable flashlight in a simple structure, specifically, a single layer body.


Q7. What should I do if the TK16 V2.0 needs repair?

A: 1. 15-day replacement: Fenix will replace identical or equal products with documented manufacturing defects within 15 days of purchase.

2. 2-year free repair: Fenix will repair a light free of charge within 2 years of purchase if problems develop with normal use.

3. Lifetime maintenance: If repair is required after 2 years from the date of purchase, Fenix will charge for parts. The total repair fee is dictated by the cost of the replaced materials.

Great flashlight!

Love it, great battery capacity, used it all day long in a dark basement on my project from 1pm to 12 midnight. Very reliable, I’m happy!

Fenix Flashlights

Have bought several fenix flash lights. Always recieve them fast and service has always been great about fixing any repairs needed and not costing me anything. The only issue i have is that the shipping cost to send back for repair should not be the responsibility of the buyer.

Love this light

I was getting tired of buying cheap gas station LED small flashlights that would break or fail and finally decided to spend some money and get a GOOD small flashlight. I'm glad I did.. This little guy is a powerhouse and the battery last a very long time. I leave it on "turbo" just because it's so fun to see it at it's brightest although for close work it's just too bright and I have to turn it down.. Great build quality, the threads for the end cap and the front are super smooth it's just a very good flashlight that was surprisingly affordable and brighter than any thing I've ever owned

Great flashlight

The brightness is great. I like the tactical buttons. I definitely like the ability to break glass if need be. I'm in law enforcement and the flashlight is definitely what I needed.

V2.0 Review

LOVE this flashlight, as a home inspector, I use this light daily, and have NEVER had a problem. Liked it so much, I have purchased 4 of the same light.

Careful not to melt your face off!

The top power setting on this light throws a whopper of a beam down the far end of the field, that’s 10 acres away.
She’s a chubby girl. Good fit in the hand, just a bit more than I want in my pocket for something like an EDC.
Perfect for a small work light or duty light.
Big fan of the battery itself being the charger…though I have to admit it had me scratching my head for a few while searching unsuccessfully around the outside for a charging port.
Great backpack or emergency light.
Also a fan of the double switch end cap. Wasn’t sure if I would like it. It’s definitely an upgrade over the single switch in my eyes.
Overall spectacular light. I’m a fan for sure. Would definitely not hesitate to purchase.
This light has me looking at a bunch more now. You’ve been warned!
Used a Fenix light like a dozen years ago professionally. Made the switch from a die hard surefire man after seeing a guy use one. I had to know. Who makes a light that small, so bright!?!
Asked him, asked if it was tough, dude spiked it on a hangar floor. Never flickered. I was sold.
Good to see after an over a decade the quality and brightness have only improved.
