Introduction: A Long-Standing Affection for Fenix Flashlights
As a long-time fan of Fenix flashlights, I was excited to get my hands on the newest addition to their lineup, the Fenix TK20R UE Rechargeable Flashlight. Having been introduced to Fenix by my brother several years ago, I’ve come to appreciate the brand’s commitment to quality build and outstanding performance. Let’s dive into this review and explore the features and performance of this impressive flashlight.
Fenix TK20R UE Design and Build Quality: Solid and Versatile
The Fenix TK20R UE is a well-made flashlight that exudes durability and versatility. Constructed from durable A6061-T6 aluminum, this flashlight is both lightweight and robust, making it ideal for various applications. Weighing in at 7.2 ounces (204g) with the battery, it strikes a great balance between size and weight, fitting comfortably in my hand and pocket. The flashlight’s dimensions, 6.05” tall, with a head width of 1.34” and a body width of 1”, make it easy to carry and use.
The inclusion of a clip allows for secure pocket carry, adding to its convenience. The TK20R UE also boasts the new FlexiSensa tactical switch, offering three modes: Tactical mode for instant access to Turbo or Strobe, Duty mode for single-tap access to all brightness levels, and Lock Out to prevent accidental activation. The intelligent memory feature remembers the last selected mode, enhancing user convenience.
Fenix TK20R UE Impressive Performance: A Spotlight in Your Pocket
The TK20R UE Rechargeable Flashlight delivers an impressive maximum output of 2800 lumens, capable of illuminating objects up to 1526 feet (465 meters) away. A single Luminus SFT70 LED fuels this impressive performance, emitting a cool white light around 6500K, similar to carrying your own spotlight, capable of illuminating a distance of nearly 0.289 miles.
The flashlight offers six different modes, including Turbo (2800 lumens), High (1000 lumens), Medium (350 lumens), and Low (30 lumens) in Duty mode, and Turbo and Strobe in Tactical mode. The beam’s hotspot is crisp, complemented by a smooth corona and a wide spill area, ensuring a satisfying and practical illumination experience.
Fenix TK20R UE Rechargeable Power and Battery Life
The Fenix TK20R UE has been a game-changer for me, as it comes with a powerful 21700 rechargeable lithium-ion battery, which outperforms the more commonly used 18650 batteries in terms of capacity. With an impressive 1400 watts capacity, this flashlight delivers exceptional performance and extended runtime, making it a perfect companion for my outdoor adventures and professional needs.
On those long camping trips or during emergencies, the TK20R UE’s low mode can run for a remarkable 40 hours, providing me with a reliable light source that I can always count on. The extended battery life is great when I don’t have immediate access to charging facilities.
The convenience of the USB Type-C charging cable is a real game-changer, making recharging a breeze. I appreciate that the Type-C charging port is cleverly hidden beneath a collar, which I can easily unscrew to access the port. Plugging in the USB Type-C cable initiates the charging process, and thanks to the faster charging capability of the Type-C technology, the included Fenix ARB-L21-5000 V2.0 battery typically reaches a full charge from complete depletion in about 3.5 hours.
The flashlight keeps me informed throughout the charging process with its LED indicator. While charging, the indicator glows red, and once the battery is fully charged, it switches to green, signaling that the flashlight is ready for action. To maintain its dustproof and waterproof properties, I make sure to tighten the light head securely after charging.
Thoughts on USB Charging Port
One thing I noticed is that the USB charging cable might not seat all the way into the charging port. While this doesn’t impact the charging process itself, it did give me a moment of concern initially, making me wonder if the connection was secure. However, after a few uses, I got used to it, and the USB Type-C charging has remained reliable and efficient.
Overall, my experience with the Fenix TK20R UE Rechargeable Flashlight has been exceptional. Its rechargeable power and extended battery life make it a reliable companion for all my outdoor activities and professional needs. With the added convenience of USB Type-C charging, the flashlight is always ready to light up my path, ensuring a dependable and powerful light source whenever I need it. Whether I’m out camping, hiking, or facing an emergency, the Fenix TK20R UE is the trustworthy flashlight that I can rely on without hesitation.
Fenix TK20R UE Temperature Testing: A Word of Caution
As part of the testing process for the Fenix TK20R UE Rechargeable Flashlight, I conducted temperature testing to assess its performance under prolonged use, particularly in Turbo mode. While the flashlight is equipped with intelligent overheat protection to prevent excessive heat buildup, it’s essential to exercise caution when using Turbo mode for extended periods.
Temperature Testing Results:
Turbo Mode Heat Output:
During extensive testing of the Fenix TK20R UE flashlight, I observed that the head temperature increased rapidly when operated in Turbo mode. Starting at an initial temperature of 80.7 degrees Fahrenheit (27 degrees Celsius), the head temperature surged to 104 degrees Fahrenheit (40 degrees Celsius) within just 6 minutes of continuous use.
While aiming the flashlight at distant objects, I observed that the intense beam’s heat could affect nearby surfaces. When directed at a deck board, its temperature increased from 86.1°F (30°C) to 102.2°F (39°C) within 30 seconds. This highlights the importance of caution when using Turbo mode near heat-sensitive objects.
Considering these test results, it is evident that the Turbo mode is designed for brief bursts of maximum output rather than continuous operation. For longer periods of use, the High mode, with its ample brightness and less heat generation, proves to be more suitable.
The Fenix TK20R UE is equipped with intelligent overheat protection, which automatically reduces the output to prevent the flashlight from reaching unsafe temperatures. As a result of the overheat protection, the brightness gradually decreased as the head temperature increased. This feature ensures that the flashlight remains safe to use even during extended operation.
Direct Skin Contact:
After operating the flashlight in Turbo mode for a few minutes, I attempted to touch the head of the flashlight directly with my skin. Due to the significant heat generated, I immediately pulled my hand away, as the head was too hot for direct contact. This demonstrates the importance of avoiding skin contact with the flashlight’s head, especially when operating in Turbo mode.
Given the temperature testing results, it’s important to use the Turbo mode sparingly and with caution. The Turbo mode is designed for brief bursts of maximum output when an intense beam is required. For general illumination and extended use, the High mode provides ample brightness without generating excessive heat.
