The ultra-powerful rechargeable flashlight Fenix LR50R V2.0 delivers an extreme luminous flux of up to 18000 lumens (ANSI) and an astonishing throw of 846 meters. It achieves its performance using six powerful Luminus SST70 LEDs with a lifespan of 50,000 hours. These are newly supplemented by a strong 10 W UV LED with a black filter for professional inspections and a red LED, whose light preserves night vision adaptation. The flashlight is powered by a massive Li-ion battery pack with a staggering capacity of 32000 mAh (115.2 Wh), which is integrated into the handle. The innovative user interface combines an electronic button and a rotary switch for stepless output regulation. In real time, the smart OLED display informs you about the flashlight's status.

The flashlight features two hidden USB-C charging ports. Through them, it can not only be charged at lightning speed (supports simultaneous fast charging via both ports), but it can also be used as a high-performance power bank to charge other devices (supporting output up to 45 W). Thanks to stepless output regulation, you can set the exact brightness you need. Despite its massive performance and huge battery capacity, the flashlight maintains reasonable dimensions – the length is 21.8 centimeters and the weight is 1150 grams including the battery. For comfortable carrying, it is equipped with an ergonomic non-slip shoulder strap with an emergency whistle. This uncompromising searchlight is perfectly suited for rescue and reconnaissance operations, guarding large facilities, professional inspection deployment (thanks to the UV light), or for the most demanding flashlight enthusiasts.

All parameters of the flashlight (luminous flux, battery runtime, waterproofing, throw, and impact resistance) are measured in accordance with the ANSI/NEMA FL 1-2009 standard.

Usage

On/Off: When the flashlight is locked, rotate the rotary switch clockwise to turn it on to white light. To turn it off and lock it, rotate the switch counterclockwise until it stops. When the flashlight is off or locked, double-click the electronic switch to turn on the colored light. When the flashlight is unlocked, press and hold the electronic switch for 0.5 s to turn it on/off.

Mode switching: With the flashlight turned on, single-click the button to cycle through Spotlight -> Floodlight -> Combined mode. To enter the Red and UV light modes, quick double-click the button (while turned off or locked). Subsequent clicks cycle through: Red light -> Red flashing -> UV light.

Stepless output regulation: In any of the white or red light modes, the brightness can be steplessly adjusted using the rotary switch.

Strobe and SOS: In the unlocked state, hold the button for 1.2 seconds to activate the Strobe. A short click then switches to SOS. Hold the button longer (1.2 s) to exit the flashing modes.

Locking the flashlight: By rotating the rotary switch fully to the left (counterclockwise), the flashlight turns off and is locked against accidental activation (e.g., in a backpack). To unlock it, simply turn it to the right.

Intelligent proximity sensor: If the flashlight reflector approaches an obstacle at a distance of approx. 6 cm for more than 1.5 seconds, the output will automatically decrease to 50 lumens. Once the obstacle is removed, the output gradually returns. The function can be deactivated: with the flashlight locked, hold the button for 6 seconds, and the flashlight will flash 8x (function disabled). To turn it back on, repeat the process (the flashlight will flash 2x).

Overheat protection: The flashlight generates heat during prolonged use at high outputs. Once the temperature exceeds 65 °C, the electronics smoothly reduce the output for safe cooling. After the temperature drops below 65 °C, the output gradually increases back to the original level.

Charging
