Fenix TK25R Tactical Flashlight

For those who crave more than a standard flashlight, the Fenix TK25R delivers an entire lighting arsenal in one rugged build. With 3600 lumens of max output and a beam that reaches 1148ft (350m), this flashlight is a mega-powerhouse designed for users who love advanced gear with insane beam throw.

The unique mode toggle switch on the tail of the TK25R allows you to quickly switch between three operating modes: Duty, Tactical Support, and Lockout. When Duty mode is selected, the flashlight operates with just the forward-facing white light. When in Tactical Support mode, you can access an array of lighting options built into the side of the flashlight’s head, including two levels of diffused white light, UV light, red light, red flash, and a red/blue flash for signaling. Lastly, select Lockout mode when the flashlight is not in use to avoid accidental activation.

Additional features include Instant Turbo, which lets you bypass all other brightness levels to reach Turbo instantly, 1.5-hour fast USB-C charging, and a durable build with IP68-rated waterproofing. The TK25R is bold, complex, and unapologetically overbuilt.

*21700 Li-ion batteries are powerful cells designed for commercial applications and must be treated with caution and handled with care. Using low-quality batteries or mishandling batteries (such as short-circuiting or overheating) could lead to combustion and jeopardize the safety of users and property.

Usage and Maintenance

• Disassembling the sealed head can cause damage to the flashlight and will void the warranty.
• Recharge the battery in time to ensure normal use for next time.
• Fenix recommends using an 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 explosion.
• Lock the flashlight or take out the battery to prevent accidental activation during storage or transportation.
• 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 flashlight and battery contacts improves the flashlight's performance as dirty contacts may cause the flashlight to flicker, shine intermittently or even fail to illuminate for the following reasons:

  A: Poor battery level.

  Solution: Recharge or replace the battery.

  B: The contact or contact point of the battery or flashlight is dirty.

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

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