The Fenix LR35R PRO is an extremely powerful and versatile flashlight designed for exceptional performance in any situation. It delivers a dazzling output of up to 10,000 lumens and a maximum beam distance of 500 meters. For maximum versatility, it combines several specialized light sources: a 5,000-lumen spotlight, an 8,000-lumen floodlight, a red light (260 lm), and a powerful 3.7W UV light.

Operation is fast and intuitive thanks to the combination of a rotary switch for stepless brightness adjustment and an electronic switch for mode switching. It is powered by two high-capacity 6000mAh 21700 Li-ion batteries (included), providing a runtime of up to 135 hours. With its two-way USB-C port supporting 18W fast charging, the flashlight can not only be quickly recharged but can also be used as a power bank for your other devices, such as a smartphone.

Operational safety is ensured by an intelligent overheat protection system, which automatically reduces the output at high temperatures. The stainless steel strike bezel is embedded with tungsten steel breaking tips, allowing for instant window breaking in emergencies. A lockout function to prevent accidental activation is also included. The flashlight is built to withstand the toughest conditions—it is fully dustproof and waterproof to the IP68 standard and impact-resistant to drops from 1 meter. This makes it an ideal companion for search and rescue operations, outdoor adventures, and professional use.

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

How to Use the Fenix LR35R PRO Flashlight

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

Mode Switching - With the flashlight on, press the electronic switch to cycle through the white light modes: Spotlight → Floodlight → combination Spotlight + Floodlight. With the colored light on, press the switch to cycle through the modes: Red Light → Red Flash → UV Light. With the flashlight unlocked, press and hold the electronic switch for 1.2s to enter the flash modes. Single presses of the switch will then cycle between Strobe and SOS. Pressing and holding the electronic switch again will return to the last constant lighting mode.

Stepless Brightness Adjustment - In white, red, and UV light modes, the output can be steplessly adjusted with the rotary switch. Turning it clockwise increases the output, and turning it counter-clockwise decreases it.

Lock/Unlock - To lock the flashlight, turn the rotary switch counter-clockwise until it stops. To unlock and turn on the flashlight, turn the rotary switch clockwise.

Last Mode Memory - The flashlight automatically memorizes the last selected lighting mode. When turned on again by turning the rotary switch or holding the electronic switch, the previously used white light mode will be restored. When turned on again by double-pressing the electronic switch, the previously used colored light mode will be restored. The flashlight does not memorize the previously used output level.

Battery Replacement - Unscrew the flashlight body and insert both batteries with the positive pole towards the head. Then, fully tighten the body again. The flashlight can be used with only one battery inserted, but its output will be reduced.

Charging - Turn off the flashlight, open the dust cover, and plug the USB-C charging cable into the flashlight's charging port. After charging is complete, seal the dust cover again. During charging, five green indicator lights flash from left to right to indicate the charging status. The typical charging time for the included ARB-L21-6000 batteries is 4 hours using a 27W power source. It is forbidden to charge the flashlight without batteries inside.

Power Bank Function - Open the dust cover and plug the USB-C charging cable into the flashlight's charging port, and connect the other end of the cable to the device you want to charge. After discharging is complete, replace the dust cover. During discharging, five green indicator lights flash from right to left to indicate the discharging status.

Note: The flashlight can be used while charging or discharging, but the maximum available output is limited to 200 to 900 lumens, depending on the current charge level and the mode used.

Battery Level Indication - After turning the flashlight on, or after pressing the switch while the flashlight is off, the indicator lights above the electronic switch will light up for three seconds. If five lights are on, the batteries are more than 80% charged. Four lights indicate 60-80% capacity, three lights 40-60%, two lights 20-40%, and one light 1-20%.

Low-Battery Warning - If the battery voltage drops below the set level, the flashlight will downshift to a lower brightness level. After reaching the lowest output, the battery level indicator will start flashing to remind you to recharge or replace the batteries.

Intelligent Proximity Sensor - The flashlight has a built-in safety circuit. When the head is less than 6 cm away from an illuminated object for more than 1.5 seconds, it will automatically downshift the output to 50 lumens to prevent damage to the object from the intense light and to avoid glare from reflected light. When moved away, the output will automatically be restored.

• Disabling/Enabling the Proximity Sensor - To disable the function, lock the flashlight and hold the electronic switch for 6 seconds. The flashlight indicates that the function is disabled with six flashes at 50 lumens. The function is re-enabled by holding the switch for 6 seconds while the flashlight is locked. The flashlight indicates that the function is enabled with two flashes at 50 lumens.

Note:

• After changing the current mode, it takes about 1 second for the flashlight to recalculate the remaining runtime. During this time, 'CHECK' will be displayed on the OLED screen.
• If the battery level is 5% or lower, a blank battery icon will be displayed on the screen. In this state, only the low mode of the floodlight can be used.
• After replacing the batteries, it takes 5 to 8 seconds to reload the remaining runtime, 'LOADING' will be displayed on the screen, and the flashlight cannot be used during this time.

Intelligent Overheat Protection - When using the flashlight in high output modes for extended periods, it will accumulate a lot of heat. When the flashlight reaches a temperature of 55°C or higher, it will automatically step down the output by a few lumens to reduce the temperature. When the temperature drops below 55°C, the output will gradually increase again.

Warning

• Keep this flashlight out of the reach of children!
  
• Do not shine the flashlight directly into anyone's eyes!
• Do not shine on flammable objects at close range to avoid damaging them or causing a fire hazard due to high temperature!
• DO NOT USE the flashlight in an inappropriate manner, e.g., by biting it in your mouth, to avoid personal injury or life-threatening situations in case of flashlight or battery failure!
• This flashlight accumulates a significant amount of heat during operation in high modes, resulting in a high surface temperature. Be mindful of safe use to avoid burns.
• Turn off and lock the flashlight to prevent accidental activation if it is placed in an enclosed and flammable environment, such as pockets and backpacks!
• Do not disassemble the sealed parts of the flashlight yourself, as this will void the warranty.
• Never use batteries with different charge levels or different capacities.
• Use only high-drain 21700 Li-ion batteries with a protection circuit; otherwise, the flashlight may not function correctly.
• If the protective rubber rings appear damaged after a long period of use, replace them. The rings also need to be lubricated to prevent rubber erosion. By following these rules, the flashlight will be properly protected against water.
• If the flashlight flickers, does not switch to higher output modes, or does not turn on, it may be due to one of the following reasons:
  • The batteries are nearly depleted – replace or recharge them.
  • The contacts inside the flashlight are dirty – clean them with a cotton swab soaked in alcohol.
  • The flashlight body is loose – add lubricant to the sealing rings and tighten it.
