The Fenix LR50R 12000 lumen flashlight is the definition of a high-performance spotlight. Blasting a maximum 12000 lumens, this flashlight can throw that light an incredible 3117ft (950m)—that’s over half of a mile. The Fenix LR50R’s most unique feature is its intelligent downshifting sensor which recognizes when the flashlight’s head is too close to an object and will automatically downshift the brightness level to avoid accidents due to excessive heat. The included li-ion battery pack not only powers its eight lighting modes, but you can also use its discharge function to charge other devices. Perfect for situations where maximum brightness over long distances is a must, the Fenix LR50R Rechargeable Flashlight will light up the night.

Intelligent Brightness Downshifting Sensor
The flashlight has a built-in intelligent sensing circuit. When the light surface is close to the lighting object (about 60mm) for more than 1.5 seconds, the flashlight will automatically downshift the output level to Eco to avoid danger caused by high temperature. When the light surface is more than 0.8 seconds away from the lighting object, the flashlight automatically recalls the previously used output level.

*As objects of different materials and colors reflect differently to light, there will be slight deviations in the sensing distance.

Intelligent Protection
Time-limited downshift
With the light switched on, if Turbo is being selected for over 20 seconds, the light will downshift until to 8000 lumens within 60 seconds.

With the light switched on, if High II is being selected for over 60 seconds, the light will downshift until to 4000 lumens within 60 seconds.

Note: The abovementioned functions are specially designed for avoiding discomfort and danger caused by overheating.

Overheat Protection
The light will accumulate a lot of heat when used on High I, High II or Turbo output level 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 those modes.

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 battery level indicator blinks to remind you to timely recharge or replace the battery.

Note: This only works with the included Fenix ARB-L52-16000 battery pack.

    I’ve been collecting flashlights a long time and have many top brands. Of all those, Fenix is my favorite brand. Their reliability and their durability are the best of any flashlight I’ve ever used. And when I say used, I mean used in an industrial setting, day in and day out. These are very well engineered flashlights. The buttons are always intuitive and easy to learn. They don’t get too hot when you use them, even on higher settings.
    Specifically on the LR50R, I really like the size. It fits my hand perfectly. It’s not too heavy and even has a strap, if you need it. The brightness levels cycle from the humble 50 lumens all the way up to a retina scorching 12,000 lumens. I generally use it on the 350 lumen setting(low), which is great for most tasks. It will remember which setting you leave it on after you turn it off. Turning the Turbo off and on is a one click process and doesn’t affect your regular brightness setting. I like that feature. I have never had a flashlight with the auto dimming feature, but as flashlights get brighter and hotter, that seems like a smart thing to do.
    My only real complaint was that the instructions are written so tiny, that I could not even read them with a magnifying glass. I had to go online and find an instruction manual and make it big enough to read. Not a big deal, but everything should come with instructions that are in a normal, readable size. That little gripe aside, I am very pleased with this flashlight.
