Runtimes
The body and the materials
The Fenix LR50R is defined as a "searchlight". Usually the so-called "searchlights" are large flashlights, particularly powerful and with beams capable of reaching long distances: the Fenix LR50R in fact has all these characteristics.
It weighs almost 1kg, but the feeling you get when holding it in your hands is that of handling a product of the highest quality and sturdiness. The dimensions are important but not excessive: the battery holder tube has a diameter of about 6cm, almost like that of a can of coke, while the head is a little wider and reaches almost 9cm.
Given the weight and size, Fenix has seen fit to provide a carrying strap with metal snap hooks bundled with the flashlight. Installation is simple thanks to the large holes on the tailcap and the ring that can be screwed sideways on the body of the flashlight.
The package also includes a wrist lanyard in my opinion not very useful and perhaps a little inconvenient to use on a flashlight of this size.
The LR50R comes together with a practical rigid Nylon holster where the torch is placed with the head facing upwards.
The light is blocked by means of a tear-off band that wraps around the head. On the back there is a large belt loop, a second loop with velcro closure and a large plastic D-ring.
The user interface is managed by the two electronic switches placed laterally near the head: the first, the one on the left, is defined as "auxiliary" and useful for managing the functional mode, while the one on the right is used to use the flashlight in general.
Just above the two switches we find 4 small blue status LEDs that provide information on the residual capacity of the batteries and on the charging progress.
The head is large and equipped with a series of deep and thick dissipation fins. The body has no knurling but horizontal and vertical millings which always guarantee excellent grip. Well done HA III type anodizing, slightly opaque and smooth to the touch.
The threads are anodized, smooth and arrive well lubricated. Physical lockout of the interface is allowed by slightly unscrewing the battery tube.
The head side contacts are composed of two concentric metal rings for power supply and a central contact that allows the LR50R to understand if the original battery pack is installed or if you are simply using 21700 cells. On the tail side instead (negative pole) there are 4 thick golden springs.
The optical part is made up of 4x 6000K SST70 LEDs well centered with white centers inside a smooth and mirror polished multiparabola. The lens is made of glass, thick and with anti-reflective treatment. The bezel is in brushed steel and is rather protruding. Fenix claims that the beam produced by the LR50R has a spot of only 8 degrees and a spill of 75.
On the dish it is possible to notice the presence of some sensors: these have the task of detecting the presence of obstacles in front of the lens up to a distance of 60mm. Once an obstacle is detected for more than 1.5 seconds in front of the lens, the LR50R will automatically switch the output to ECO level to avoid possible damage caused by high temperatures. By moving the flashlight away from the obstacle, the output will return to the previously selected level.
The power supply is guaranteed by a 16000mAh battery pack consisting of 4 21700 4000mAh batteries placed in parallel (4P), and equipped with a protection circuit. A small pin on the battery pack, as mentioned above, provides the flashlight with the information that the original battery pack has actually been installed.
The Fenix LR50R can also be powered with classic 21700 cells, but beware !!! Because in this case it will not be possible to use the Turbo level of 12000 and the maximum usable output will be the High II of 6000 lumens. In this way Fenix "forces" LR50R owners to use original battery packs if they want to have the maximum output of 12000 lumens. Otherwise, using the classic 21700 cells the maximum output available will be only 6000 lumens!
Obviously I find it useful that the LR50R can be used both with a proprietary battery pack and with the classic 21700 cells but the difference in maximum output between the two options leaves me a little perplexed. Why such a choice? Security Matters? Or is it a choice dictated only by commercial purposes? I asked Fenix for clarification directly and he replied telling me that the battery pack supplied with the LR50R is more efficient in terms of discharge current than the original Fenix 21700 batteries. Ok XD!
The parallel power supply system allows the torch to be powered with 4 but also with only 1, 2 or 3 cells. The flashlight will still work but the runtimes will decrease proportionally. The 6000 lumen "Turbo" (High II) can be recalled in any case.
A very useful function that the Fenix LR50R has is that of a powerbank. In fact, it is equipped with a bi-directional Type-C port that acts as a charging port for the internal batteries and a fast charge charger for any type of electronic device. To charge the flashlight and to use it as a powerbank, Fenix has included a USB - TypeC cable that turns into a Type-C - Type-C if necessary.
The status LEDs located above the switches light up in sequence during the charging phase, while during the use of the flashlight they indicate the amount of remaining charge as follows:
• 4 LEDs on: charged between 100% and 80%
• 3 LEDs on: charge between 80% and 60%
• 2 LEDs on: charge between 60% and 40%
• 1 LED on: charge between 40% and 20%
• 1 flashing LED: charge between 20% and 1%
On the side, the flashlight has a 3/8 screw connection for tripods. A metal adapter is supplied which also acts as a ring for connecting the carrying strap and which brings the connection from 3/8 to 1/4.
The tailcap is not flat but still allows tailstanding. There are also two large holes for inserting the laynard.
User interface

• Press and hold the right main switch for 0.5 sec to access the last used mode (general mode)
• Press and hold the left auxiliary switch for 0.5 sec to enter Turbo (functional mode)
• Press and hold either switch to turn off the flashlight
Output selection
• From the flashlight on, click on the main right switch to scroll through the levels: Eco -> Low -> Med -> High I -> High II -> Turbo
• From the flashlight on, click on the left auxiliary switch to access the Turbo and to scroll through the levels: Turbo -> Strobe -> SOS
Strobo
Press and hold the left auxiliary switch for 0.5 sec to enter Turbo (functional mode)
Turbo access
• Press and hold the left auxiliary switch for 0.5 sec to enter Turbo (functional mode)
• Scroll through the levels of the general mode using the main right button until you get to the Turbo
Memory Mode
• The LR50R memorizes the last level used by the user to propose it again at the next power on.
• Level storage mode is not active when using 21700 cells.
• The functional modes Turbo, Strobe, SOS are not memorized, so clicking on the left switch will always access the Turbo directly.
Avviso di bassa tensione
When the battery is about to run out, the flashlight will decrease the output to the ECO level and then turn off.
Lockout mode
• With the flashlight off, keep both buttons pressed to electronically lock the flashlight. Repeat the operation to unlock it.
• If you press the switches while the torch is locked, two flashes will be emitted to inform the user that you are in lockout mode.
Charge level indication
• With the flashlight off, click on one of the two switches to find out, via the status LEDs, the amount of residual charge in the cells.
Beam, Tint and Beamshots
The beam of the Fenix LR50R is purely for shooting with a narrow and very bright spot and a wide and very bright spill. The geometry of the beam due to the multiparabola is not linear, the shape almost resembles that of a four-leaf clover.
The color is cold, 6000K but uniform on the whole beam and without any strange toning.
Here are some shots in the dark
Conclusions
Pro:
• Excellent build quality, abundant thicknesses, perfect anodization, reactive switches, fluid and sliding threads
• Double switch and status LED
• Good Turbo power
• Excellent regulation
• Thermal protection always active
• Excellent heat dissipation
• Fast charging via Type-C
• Powerbank function with fast charging function
• Simple user interface
• Proximity sensors
• Packed full of accessories
• Possibility to use 21700 cells instead of the battery pack *
Cons:
• * When using non-proprietary cells the flashlight behaves differently: the 12000 lumen Turbo cannot be used and the Memory Mode does not work
• The user interface, albeit simple and complete, doesn't drive me crazy: I don't really like the long press to turn it on and off and I don't find it useful that the Turbo has been inserted into the cycle of levels of the general mode. For example, I would have preferred a hidden Turbo that can be recalled directly with a double click ... but these are just personal tastes
To conclude and as seen in this test, I can only say that the Fenix LR50R is an exceptional product and certainly to be recommended !!!
