The powerful Fenix TK25 IR tactical flashlight offers a peak luminous flux of up to 1000 ANSI lumens of white light and in addition two infrared LEDs with a 850 nm wavelength and a maximum power of 3000 mW. This wavelength is compatible with most night vision systems. The flashlight can be powered by two disposable CR123A batteries or one high-capacity Li-ion 18650 accumulator (not included in the package). A very solid and waterproof design and a two-layer construction of the body predestines this tactical flashlight for harsh outdoor conditions, for professionals, armed forces and hunting. The Fenix TK25 IR flashlight uses a dual tactical switch that enables faster and more reliable control in crisis situations. For example, it can be easily switched directly to stroboscopic mode. The flashlight is powered by a digitally controlled constant current to guarantee a constant light output even when the voltage in the batteries is reduced (while they are slowly discharging). 

Fenix TK25 IR has a total of five white light modes with a duration of up to 110 hours and two infrared light modes.

Switching between white and infrared light mode is very easy, just turn the head of the lamp by 90°. Due to the magnetic sensors in the head of the flashlight, however, it cannot be used with magnetic mounting on a weapon, which interferes with its proper function.

All parameters of the flashlight (luminous flux, battery life, waterproofing, afterglow and impact resistance) are measured in compliance with the ANSI/NEMA FL 1-2009 standard.

Fenix TK25 IR LED parameters:

Fenix TK25 IR flashlight operation

To turn it on, press the larger button located at the end of the flashlight, for immediate activation, press the button. By pressing the secondary switch button, you can switch between power modes at any time during operation. To switch to flash mode, hold down the switch button for about 1 second while the flashlight is on. Press and hold the toggle button to turn the flashlight directly into strobe mode. It switches between white and infrared light modes by turning the lamp head by 90°.

Removal of the clip - unscrew the tactical ring and pull the clip off the body of the flashlight, screw the tactical ring back.

Warning

• Use only high-quality 3V CR123A batteries and 18650 li-ion batteries to avoid damage to the flashlight, for example due to leakage of substances from the battery.
• Insert the batteries with the positive pole towards the head of the torch.
• If the protective rubber rings appear damaged after prolonged use, replace them. The rings must also be lubricated to prevent rubber erosion. By following these rules, the lamp will be properly protected against water.
• If the flashlight flickers, does not switch to higher power modes, or does not light up, it may be for one of the following reasons:
  • Batteries are almost dead – replace them.
  • The contacts inside the lamp are dirty – clean them with a cotton swab dipped in alcohol.
  • The head, body or back of the lamp is loose, tighten it.
