Fenix TK20R v2.0, 3000 Lumen, 21700 Powered, USB-C Rechargeable, APF Flashlight, Black

Product Information

Long-term use can result in O-ring wear. To maintain a proper water seal, replace the ring with an approved spare. 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.

Once again Fenix has proven two things: One, they know how to make a great flashlight, and two, they’re an innovative brand that endeavors to keep making great lights. The proof is in the pudding, because so far, this is the 5th Fenix light I’ve reviewed that’s a 2nd (or 3rd in the PD35 V3’s case)generation of an existing product, and they’ve all featured meaningful and effective upgrades. 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. I tested the runtimes in the 30 cm integrating sphere using the Digi-Sense 20250-00 datalogging luxmeter. I tested Medium, High, and Turbo modes utilizing the fully charged included battery. 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.

Tap the tactical switch to silently and momentarily turn on the light, releasing the light will go out. Do not shine an object at close range, to avoid burning the object or causing danger due to high temperature. Equipped with a powerful Luminus SFT70 LED and powered by one high capacity 21700 rechargeable lithium-ion battery, the Fenix TK20R V2.0 puts out a superb performance with a beam distance of 475 metres in turbo.

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. A. The TK20R carries a waterproof rating of two meters. Rain and snow won’t be a problem, and it can handle being temporarily submerged. It’s not a dive light though, so don’t plan on raiding Alcatraz with it. Q. Can the TK20R be used as a weapon light? Fenix doesn’t conceal the identity of the LEDs they use, which I think is a nice concesion for consumers who care about such things. Whereas the majority of Fenix’s higher output lights are fielding the Luminus SST70, for the TK20R V2 it’s been booted in favor of its domeless stablemate, the SFT70. This is an entirely new LED, and hasn’t had much exposure in the flashlight continuum. I can’t find a data sheet for this LED, and I haven’t seen it featured in any other mainstream lights besides the Olight Warrior 3 and 3S. I do know it’s a 5050 (5mm x 5mm) footprint, so it fits anywhere the SST70 fits, and it runs on 6 or 12 volts. Like the SST70, it retains the quad die arrangement on a single substrate. The dies are pretty close together, but not as close as something like an XHP35 HI, and the design is similar to the SFT-40-W in that the bond wires are embedded in the substrate. This helps current handling and heat dissipation at higher drive currents. 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? If the lamp will not be used for an extended period, remove the battery, or the lamp could be damaged by electrolyte leakage.
