The maximum output has been upgraded all the way up to 3100 lumens! Not only that, but a larger head allows for a beam distance upgrade as well with a new beam throw of 1246 feet! Lastly, the larger battery also means a larger battery capacity, allowing for an increased maximum runtims, up to an amazing 43 hours.

Warning: Please do not mix batteries of different brands, sizes, capacities or types. Doing so can cause damage to the flashlight or the batteries being used.

*18650/16340 Li-ion batteries are powerful cells designed for commercial applications and must be treated with caution and handled with care.

Battery Replacement

Unscrew the tail cap to insert the batteries with the anode side (+) toward the light's head, screw the tail cap back on.

Usage and Maintenance

◎Disassembling the sealed head can cause damage to the light and will void the warranty.

◎Fenix recommends using excellent quality battery. If the flashlight will not be used for an extended period, remove the battery, or the flashlight could be damaged by electrolyte leakage or battery explosion.

◎Unscrew the tail cap one-half turn or take out the battery to prevent accidental activation during storage or transport.

◎Low-voltage Warning Function: When the voltage level drops below the preset level, the flashlight is programmed to downshift to a lower brightness level. When this happens in Low output mode, the flashlight blinks three times every five minutes to remind you to replace the battery. To ensure normal use, the flashlight will not turn off automatically and will work until the batteries run out completely.

◎Long-term use can result in O-ring wear. To maintain a proper water seal, replace the ring with an approved spare.

Reason A: The batteries need replacing.

Solution: Replace batteries (Please confirm the correct installation of anode and cathode).

Reason B: The threads, PCB board contact or other contacts are dirty.

Solution: Clean the contact points with a cotton swab soaked in rubbing alcohol.
