Dual Switches

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


Tap the tactical switch to momentarily turn on the light; the light will activate last memorized output on White mode, or Red high on colored 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 mode, or to enter Red high on colored mode; release it and the light will go out.


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 colored mode – single click the functional switch to cycle through Red High→Red Low→Blue.

Mode Switching

Rotate the light head to switch between white and colored light.

Intelligent Memory Circuit

The light memorizes the last selected brightness level on White light mode. 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 and Red flashes on colored light.)

Intelligent 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 batteries need replacing.
    Solution: Replace batteries (Ensure batteries are 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.

    I’ve had this light for only less than a year, but allow me to qualify my review as I have gone through many flashlights before finding this one. I work in fire aviation for a federal land management agency. I use this light as a signal strobe for aircraft that I coordinate with from the ground. It’s been dropped in the dirt, hot ash, mud, rocks and more. I use the R&B functions for tracking at night and photography purposes on my personal time as well. It’s seen heavy use with me and still works like new. And the Fenix 18650 batteries are awesome as well. I have gone 2 weeks on assignment on a single battery and have just 2 that I rotate between. My only complaint is that I wish it had a lock. It turned on in my pack once and melted through the holster strap. But it’s incredible! Don’t think I will ever buy a light from another company again.

    Haven’t had this light long but so far it’s lived up to it’s Fenix pedigree. Holding on a 5 rating only for that reason, otherwise an excellent multi function light. The dial beam selector and push button switch combination is well thought out and works smoothly but solidly. Great light so far!

    seems to be a great flashlight. Bought it for tracking deer. No opportunities yet, but hopefully I’ll have a chance to see how it works before the end of the season!

    Excellent flashlight. Easier to use than the instructions were to read. Nice glass lens. Correct red + blue wavelengths. Rotating head great feature. Only white/red/blue flashlight I could find since Pelican quit making theirs. Very good customer service with nice help understanding features before buying. Fast shipping too. And cheaper than Amazon !!

Fenix TK25 R&B Flashlight Review from Hunting Ambassador

Mike K.
Mike K., Reviews the TK25 R&B Red/Blue light Flashlight I applied to test/review the TK25R&B for several reasons. Among them was a desire to review a flashlight from a layman's point of view. I find the technical reviews to be extremely informative, but sometimes a bit overwhelming for those who aren't necessarily addicted to flashlights…
