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.

This flashlight is a high-intensity lighting device capable of causing eye damage to the user or others. Avoid shining the flashlight directly into anyone’s eyes.

    So far so good. I inspect homes, and this flashlight is great at throwing light in a very tight beam for a long distance. I also have a TK47, which has an even more concentrated beam, but it is longer and not very convenient in a lot of spaces I find myself in. The TK22 is great for those enclosed spaces. Very satisfied so far and, frankly, don’t expect anything but that.

    I have 3 other Fenix flashlights which produce 1000 lumens. The new flashlight is even more incredible.

    Once again Fenix did not disappoint. In fact they over delivered as they always do. I have so many Fenix lights because they are so well made and their customer service is fantastic.

    Powerful light with a usb-c type charger built in to the battery and a glass breaker on the bezel. Typical great service from Fenix. I own several lights from Fenix and all are high quality and very dependable. I am extremely happy with my purchase.
