It will light up for 3 seconds whenever you turn on the flashlight so you can gauge the status of the battery. 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. The light is powered by a Fenix branded button top, protected 21700 battery (ARB-L21-5000) with a capacity of 5000mAh. I tested the capacity with my Vapcell S4 Plus charger and came away with 4863mAh. I tried the light with an unprotected button top battery and had no issues.
If the lamp will not be used for an extended period, remove the battery, or the lamp could be damaged by electrolyte leakage. The normal charging time of the included FenixARB-L21-5000 V2.0is approximately 3.5 hours from depletion to full charging. We began working with Fenix in February 2007 by selling their very early products and are proud to have worked with them ever since, with our company ethos proudly putting premium product quality and outstanding service at the core of our identity.
CUSTOMER REVIEWS
The Fenix name means “a living bird, a perfect thing” and since producing their first product on 3rd of September 2001, Fenix have always strived to achieve perfection The recharging port cover is worth noting here, instead of using silicone rubber covers like many manufactures do to seal the USB-C ports, Fenix’s solution on the TK20R V2 is to have a retained aluminum cover that twists one full revolution to reveal the port. It has orings at the top and bottom and lots of anodized threads, so it’s silky smooth. Also under this port cover is the battery level indicator and recharging status LED. This just makes sense to me and has nothing to catch, or get in the way like the silicone covers sometimes do.
A:Fenix ARB-L21-5000 V2.0 is recommended. Other Li-ion batteries are not recommended. As an unmatched battery may cause the flashlight to fail to work normally. Despite their convenience, USB rechargeable flashlights are still the exception, not the norm. Thankfully, Fenix is leading the charge to bring rechargeable lights to the mainstream flashlight market. And I was thrilled to test their small-but-mighty flashlight model, the TK20R V2.0. Do NOT shine flammable objects at close range, to avoid burning objects or causing danger due to high temperature!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.
Additionally, many of these everyday carry flashlights have oversized clips that can become uncomfortable when you grip the flashlight. The TK20R V2.0 is perfect. It holds tight without extending too far off the body of the flashlight. And you can remove it if you need to. Strike Bezel Throw was measured using the Uni-T 383S luxmeter at 5 meters indoors. Readings taken at 30 seconds using the included Fenix ARB-L21-5000 V2 battery. Mode With the light switched on, tap the tactical switch to cycle through Turbo→High→Med→Low. The light memorizes the last selected output. The flashlight is a high-intensity lighting device capable of causing eye damage to the user or others. Avoid shining the light directly into anyone’s eyes.
Fenix tends to offer a lot of value with lights that perform on par with high-end manufacturers but cost significantly less. The TK20R offers more features and improved performance over a comparable Streamlight for about the same price. Surefire lights are the designer brand of the group, so expect to pay more for one of those. Q. Is the TK20R waterproof? Higher output: the APF system has made higher lumens from a forward switch possible, it breaks the limitation of current. Long-term use can result in O-ring wear. To maintain a proper water seal, replace the ring with an approved spare．
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. 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 toremind youto timely recharge or replace the battery. When the voltage level drops below the preset level, the flashlight is programmed to downshift to a lower brightness level until Low output is reached. With the light switched on, tap the tactical switch to cycle through Turbo→Strobe. The light memorizes the last selected output including Strobe.
FREQUENTLY Q&A
A lot of flashlights have a decent drop/impact rating, and this one is no exception. But when there’s a surface specifically for hitting things, I know the TK20R V2.0 will hold up to bumps and scrapes better than the average flashlight. I’ve never needed to use a flashlight’s strike bezel, but it is a good option for self-defense or if breaking a window is required in an emergency. Battery Level Indicator Trong các điều kiện môi trường đặc biệt, việc sử dụng đèn pin cần tuân theo các quy định cụ thể như sau: This new model upgrades the outgoing Fenix TK20R with an increase in output from 1,000 to 3000 lumens, an increase in beam range from 310 to an impressive 475 meters, tailcap dual switch system, 5000 mAh Fenix 21700 battery and Fenix advanced Digital Pulse Transmission signal system for a combination of ultimate power output and switch reliability.
