  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.

The new Gold Standard

I am a retired engineer and a flashlight lover. I used flashights daily in my professional career and was continually seeking the all-around best light. This is it. The Fenix TK20R v2.0 checks all the boxes.

I basically ignore the advertised max lumens since that level of intensity can generally not be maintained for more than a couple minutes. But the first step down in intensity is usually more sustainable. When that second level is 800-1000 lumens and can be sustained for a useful period it is a good light. This meets that first box.

The light distribution is perfect. A tight hot spot and nice surrounding flood. By comparison, Fenix TK16 v2.0 is a nearly identical size, shape and output, but lacks the tightly focused hot spot and resulting throw.

The dual tail switches are a great concept. The TK20R v2.0 tail switches give me easy access to power and mode without error. Again, by comparison, the siimilar TK16 v2.0 looks to have the same tail switch features BUT a subtle refinement separates the two lights. The lower/smaller Functional Tail Switch on the TK20R.v2.0 sits slightly lower relative to the Tactical Tail Switch than is found on the TK16 v2.0. I get frequent unintentional mode changes when using the Tactical switch on the TK16. Those unintentional mode changes do not occur with the TK20R v2.0.

A subtle conflict exists in modern flashlight features and design where "charging" is concerned. Some, like myself, would prefer to not have a flimsy rubber plug to cover a critical hole in my flashlight preferring to carry a spare battery and charge my spares in a external charger rather than tie-up the light for 3-4 hours while the battery is being charged internally. Others must prefer the USB charging capability. The TK20R v2.0 solves this flawlessly. For those who prefer, a USB charging, a port is provided but it is nicely hidden and protected under a threaded collar that screws down to reveal the USB port. The best of both worlds!

Finally, a word about size. The very nature of the 21700 battery dictates that this light is large for an EDC light. But carry is not impossible. It is a very compact and comfortable size and can be carried in a pocket. I'll compare or contrast this to the Streamlight Stinger 2020. The light output, pattern and battery life is similar on the two lights, but the Stinger cannot be carried in a pocket.

If you can manage the relatively higher price of the TK20R v2.0, do it. You will not regret this purchase.

Brightest of the 2TK-20r Flashlights I own!

I have owned the tk-20r for 3 years previous but this model is the brightest , a bigger battery plus a rotating safety lock ring to cover the charging plug in. (TK-20R-V2.0)

Best light

This is the best flashlight I have ever owned. I like the controls on the bottom for ease of use and the size differences for distinction. I would suggest this light to anyone. I use it for work and for any daily task I have and need a flashlight
