Operating Instruction

Dual Switches
The round switch is the tactical switch and the oval switch the functional switch.

ON/OFF
Tap the tactical switch to momentarily turn on the light; the light will activate the last memorized output on White light mode, or last memorized output on Red light mode; release and the light will go out.

Fully press the tactical switch to constantly turn on the light. Press again to turn off the light.

With the light switched off, press the functional switch for instant strobe activation on White light mode, or to enter Red high on Red light mode, release it and the light will go out.

Strobe
With the light switched on on White mode – long press the functional switch to activate strobe. Click once again to return to previous output.

Output Selection
With the light on on White mode – single click the functional switch to cycle through Low→Med→High→Turbo.

With the light on on Red mode – single click the functional switch to cycle through Low→Med →High.

Mode Switching
Rotate the light head to switch between white and red light modes.

Intelligent Memory Circuit
The light memorizes the last selected brightness level on White and Red light modes. When turned on again the previously used brightness level will be recalled.

Low-voltage Warning
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. (White light flashes on White light mode and Red flashes on Red light mode.)

Overheat Protection
The light will accumulate a lot of heat when used on Turbo output level for extended periods. When the light reaches a temperature of 65°C or above, the light will automatically step down by a few lumens to reduce temperature. When the temperature is reduced, the output will gradually return to Turbo output level.

Battery Replacement
Unscrew the tail cap to insert the battery with the anode side (+) towards the light head, then 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 an excellent 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.
  • 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.

Warning
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.

    I used my TK25 Red for the first time the other night. I bought it to use while shooting photographs of the night sky. The red LEDs really help to maintain night vision.

    As expected, being a long-time user of Fenix flashlights, it performed flawlessly. The ability to switch from white light to red so easily really makes it a winner.

    Now if it had a special mode for seeing spider webs hanging right in front of my face, and the associated spiders, they would really have something! I think I ate a few while bushwhacking down to the water’s edge.

    Absolutely killer light (in a good way). Very bright clear light. The red LED is absolutely phenomenal. Being in the Navy on the high seas a red light flashlight is crucial and my shipmates are jealous of mine. This light is one of my favorites, however, all my favorites are Fenix. Fenix has NEVER let me down.

    Mounted to my AR. I like the multiple brightness settings which allow me to use up to max brightness outdoors and lower brightness indoors. The max setting on the red light is much brighter than expected. I’m ordering another.

    Great light for night use. Red light is blinding on high.

    I compared this model to the TK25 R and B light and the reason I chose this light was for preserving my night vision. I will use it for amateur astronomy and camping. Because there is a physical separation between white and red light this is the ideal tool for astronomers because there is no way that I could inadvertently activate anything but red light even by accident while I have this rotated to the R “red” position. This makes the light as far as I can tell unique. The wavelength if I were to guess is around 620nm. I looked at the spec sheets on CREE’s website and they only advertise lumen output @ 350mw and Fenix shows 5500mw’s on their diagram so I can’t figure out what the wavelength is but rest assured it is a nice deep red and suits my needs perfectly.

    I can’t tell you how hard it is to find a solid red light flashlight, but by God Fenix has done it. This isn’t some rinky dink red light. I use it for stargazing, it doesn’t wreck your night vision like a white light will, and this sucker is powerful. Highly recommend, and customer service was great as well.
