* It is prohibited to use 18650, 16340 or CR123A batteries. * 21700 Li-ion batteries are powerful cells designed for commercial applications and must be treated with caution and handled with care. Using only quality batteries with circuit protection will reduce the potential for combustion or explosion; but cell damage or short circuiting are potential risks the user assumes. 

 

Battery Replacement Unscrew the light tail and insert the battery with the anode side (+) towards the light head, then screw the light tail back on. 

 

Charging the TK20R V2.0 

  1. Loosen the light head counterclockwise to reveal the USB Type-C charging port and plug the USB A socket of the charging cable into an electrical outlet, then connect the USB Type-C socket of the charging cable to the light.
  2. The indicator will display red while charging and will turn green when fully charged.
  3. Once charging is completed, be sure to tighten the light head to maintain the dustproof and waterproof ability.

Note: 

  1. When charging fails or the battery is reversely connected, the battery indicator will flash red to remind the user to check the battery.
  2. The normal charging time of the included Fenix ARB-L21-5000 V2.0 is approximately 3.5 hours from depletion to full charging.
  3. Recharge a stored light every four months to maintain the optimum performance of the battery.
  4. The light is unavailable while charging.

Note: This only works with Fenix ARB-L21 series 21700 rechargeable Li-ion battery. 

 

Battery Level Indication Each time the light is turned on, the indicator (unscrew the light head to see) will indicate the battery level and will last for 3 seconds. 

  • Green light on: saturated 100% - 85%
  • Green light flashes: sufficient 85% - 50%
  • Red light on: poor 50% - 25%
  • Red light flashes: critical 25% - 1%

Note: This only works with Fenix ARB-L21 series 21700 rechargeable Li-ion battery. 

 

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. Note: This only works with Fenix ARB-L21 series 21700 rechargeable Li-ion battery.

Q10. What is the APF? 

A: The APF (Advanced Pulse-frequency Transmission System) was developed by Fenix Laboratory for producing better flashlights. It has abandoned the traditional development way, breaking through the technology bottleneck, allowing flashlight with a tail switch to achieve a higher level of performance: 

1. Higher output: the APF system has made higher lumens from a forward switch possible, it breaks the limitation of current.   

2. Simpler multi-functional tail switch: this APF technology can transmit various signal commands through a single layer within the light body. Traditional signal transmission requires a multi-layer system. Thanks to this new single-layer system, the light size can be greatly reduced and the structure will be more compact. 

3. Better anti-interference performance: the APF system combats signal interference, but it doesn't work if it is applied to a magnetic switch. Therefore, the TK20R V2.0 will be less prone to interference based on the use of a mechanical switch.  

 

Q11.  Is the TK20R V2.0 battery port waterproof?

A.  The light is waterproof so long as the battery port cover is completely tightened.

 

Q12. What should I do if the TK20R 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.

Tk 16 vs tk20r

I purchased both of these great lights. I thought they would be dramatically different, but they aren't has different as i thought. The tk16 is a scosh smaller than the tk20r. I live in the Sierra Nevada mountains in Northern California in a forested area and that is the main environment for these lights. Its hard tell the difference much beam pattern at close distances, although you can tell the TK20 is a tad smaller, but they are very similar. When shining the light over a 1/4 mile lake, both lights lit up the other side, and the tk20r had a bit more of a narrow beam. My son says the TK20 looks brighter, but they are so close it is hard to tell. I love both of these lights. You cant go wrong with either one.
