*18650 /21700 Li-ion batteries are powerful cells designed for commercial applications and must be treated with caution and handled with care.

Usage and Maintenance of the TK22 Flashlight

  • Disassembling the sealed head can cause damage to the light and will void the warranty.
  • Fenix recommends using a high quality battery.
  • If the light will not be used for an extended period, remove the battery, or the light could be damaged by electrolyte leakage or battery explosion.
  • Unscrew the tail cap half a turn or take out the battery to prevent accidental activation during storage or transportation. Recharge a stored battery every four months to maintain optimal battery performance.
  • When the voltage level drops below the preset level, the flashlight is programmed to downshift to a lower brightness level until Low output is reached. 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 till the battery runs out completely.
  • Long-term use can result in O-ring wear. To maintain a proper water seal, replace the ring with an approved spare.
  • Periodic cleaning of the battery contacts improves the lamp's performance as dirty contacts may cause the lamp to flicker, shine intermittently, or even fail to illuminate for the following reasons: 
    A: The battery needs replacing. 
    Solution: Replace battery (ensure battery is inserted according to the manufacturer’s specifications). 
    B: The threads, PCB board contact or other contacts are dirty. 
    Solution: Clean the contact points with a cotton swab soaked in rubbing alcohol.

If the above methods don't work, please contact your authorized distributor.

Don’t buy this flashlight

I own three denim flashlights and they’re all great except for this one it is a totally unreliable piece of junk it never comes on and when it does it flickers and just goes out I’m very disappointed with this total overpriced piece of shit

Did you contact warranty so they can help you troubleshoot?

Great flashlight!

This is my second Fenix flashlight. Both are exceptional in brightness, reliability, even if not used for weeks at a time. I like that the TK22 UE offers several levels of brightness, with the click of a switch. I keep them in my vehicles for safety, and I use this one also for dog walking in the evening.

Alejandro Partida
Great buy for the price

This flashlight is powerful and small enough to keep in your pocket, will recommend this for its quality and value.

James Fitzgerald

I have 3 of these flashlights. Well actually 2 of the TK22's and 1 of the TK22UE's. These with out any doubt the best lights I have ever put my hands on !!! They are the 1600 lumens ones my bad I guess because I bought them just before the new one came out that's 3100 lumens wish I had been told about the new one that was coming out. But the ones I have do a really good job . Also they are well made because they have been dropped on the ground and on concrete several times and they did not break and still work perfectly.I highly recommend these lights if you are looking for a very bright light that will shine a long distance and is very roughed . The 4 different levels of brightness is a good venture too. One more thing the customer service is excellent !!

Robert Logan
Just no comparison

I recently bought the TK 22 UE and being the owner of several other top name brand flashlights, nothing compares to this one. When I received it the USB charging cord was not in the box and Jeremy from the customer service department had one to me in three days. Fenix may be imitated but they will never be duplicated. Definitely the best light for your hard earned money.
