Fenix LR50R Rechargeable LED Searchlight

The Fenix LR50R is a high performance rechargeable searchlight that boasts a maximum output of 12000 lumens on turbo and a beam range of up to 950 metres, which is perfect for large scale searches and patrolling.

Four Luminus SST70 LEDs are mounted each in their own reflector to provide massive illumination and broad versatility, which teamed with a combination of a wide 75° flood angle and 8° hot spot they deliver the perfect balance to ensure the largest area up close and further away is covered.

Two modes of functional mode and general mode are available, with the right button operating general mode and the left button operating functional mode. Press and hold the required button for 0.5 seconds to turn the light on and single presses will then cycle through eco, low, mid, high I, high II and turbo with the right button or turbo, strobe and SOS with the left button. When in general mode single press the left button to switch to turbo in functional mode, or when in functional mode single press the right button to switch to the last used output in general mode.

To prevent accidental activation the LR50R has a lockout function. To access the lockout, with the light turned off, press and hold both buttons for 3 seconds and the eco will blink twice to show it is in lockout. Press both buttons simultaneously for 3 seconds to unlock the light.

The LR50R is powered by the included customised ARB-L52-16000 lithium-ion rechargeable battery pack or it can also use one to four 21700 rechargeable lithium-ion batteries in an emergency situation, however the less batteries used the lower the outputs available will be. The included battery pack is charged inside the torch via the USB Type-C charging port using the included cable, which both support PD3.0/PD2.0 and QC3.0 / QC2.0 fast charging protocol.

Lift the dust cover and plug in the USB-C cable into the torch and plug the either the standard USB-A or USB-C end of the dual connector into a USB power source, which if supports fast charging will be autodetected and the light will charge at 4 A. The four charging indicators that sit above the two buttons will gradually illuminate until all four are solid to show charging is complete, and the cable can then be removed and the dust cover replaced.

The USB-C port of the charger also has a power bank function to allow for charging of an external USB-C device using the torch battery. Simply plug the cable into the torch and then connect the other end to your USB-C device, then single press either button on the torch to begin the discharging process of the light, and the indicators will decrease to show that the battery is being discharged.

The four LED indicators also light up when either button is pressed when the light is off when using the included battery pack. Four LEDs is 80-100% power, three LEDs is 60-80% power, two LEDs is 40-60% power, one LED is 20-40% and one flashing LED is less than 20% power and the torch should be charged as soon as possible when at this stage.

Please note:
To avoid overheating the torch has two types of inbuilt protection. The temperature protection will lower the output of the torch if the temperature reaches 60°C or above when using turbo and high II, then once the torch has cooled these modes can be reselected. The timed downshift will reduce the output after 20 seconds constant use in the turbo, down to 8000 lumens within 60 seconds, and reduce the output after 60 seconds constant use in High II, down to 4000 lumens within 60 seconds.
