Battery Specifications 

TypeDimensionsNominal VoltageRecommended
Rechargeable Li-ion battery18650*3.6VFenix ARB-L18 Series

Warning: *18650 Li-ion batteries are powerful cells designed for commercial applications and must be treated with caution and handled with care. Only use quality batteries with circuit protection will reduce the potential for combustion or explosion; but cell damage or short circuiting are potential risks the user assumes. 


Battery Replacement 

Loosen the lock catch and open the tail cap to insert the battery with the anode side (+) towards the light head, then close the tail cap and fasten the lock catch. 


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 60°C or above, the light will automatically step down a few lumens to reduce the temperature. When the temperature drops below 60°C, it will then allow the user for the reselection of Turbo mode. 


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, one of the battery level indicators blinks to remind you to recharge or replace the battery. 


Usage and Maintenance of the Fenix WT25R Adjustable Head Flashlight 

  • 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.
  • Lock the light or remove 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.

    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.

Love this light

I’m a field engineer and use this often on the job. All around great product

All rounder practical flashlight

I recently felt the need to replace an old 8 year old RC series torch and was looking for the right replacement and stumbled upon this. Looking at the design and functionality, felt that it suited my needs and bought one today. Was not disappointed.
This is a well thought out and designed tool that fits exactly what a practical flashlight should be. The battery life is good. The swivel head is perfect for putting the illumination exactly where it works best and the square design together with the magnetic base keeps it there.
The charging mechanism is easy to start and stop and charging stops automatically once the capacity is full so it can be kept on the 'leash' at all times until needed.
The clip i think could be better. While it works perfectly when you need to use the light, the inability to reverse the clip for storage in a pocket makes it extrude out and is a bit top heavy. Because of this, I just put the whole thing into the pocket instead.
The device is light and the standard 18650 battery being easily replaceable is good. All-in-all, I am expecting this to serve its purpose for a good 6-8 yrs until newer technology surpasses its functionality.

good for mechanic work

Good flashlight overall. Strong and well built, standard for Fenix. I like the magnetic charging port and the flex head. Like others have stated, the press and hold nuances are slight and can be annoying. I'd rather have a simple on/off switch (momentary) and a separate switch for function switching or locking on/off.

You're up on a ladder in a precarious position, holding on with one hand, you reach for this flashlight.........and the "safety lock" is on. No matter what you do, you can't get the lock to release. So you have to climb down and get a different flashlight.

A poor, undependable dangerous tool.

The lock function prevents accidental activation in a pocket or a bag. A quick double click is all it needs to lock or unlock:


Lock: with the light unlocked and switched off, double click the switch to lock the light, the light will blink twice on Low to indicate locked status.

Unlock: with the light locked and switched off, double click the switch, the light will be unlocked and activated on Low.

In locked status, clicking or pressing the switch will activate 2 one-second blinks on Low to indicate locked status.

I have been using this daily for the last 10 months as an automotive technician. The magnetic base and flexible head are perfect for my line of work. If you don't have a metallic surface to stick it to, the square body and flexible head still allow you to lay it down and point it anywhere you want. I have dropped it more than once on concrete and in to engine bays, and it doesn't miss a beat. Battery life is decent, especially in the lowest lumen setting, and the light is still plenty bright. For being a work light, it throws farther than you would expect, but it does have a much larger hotspot and less throw than a Streamlight Stinger, for example. I would much rather use the WT25R for the closeup work I do. That being said, this light would be even better if it had a moonlight or low lumen mode. The other major thing I would change is to make the light turn on and off with a quick press of the single side switch, not the 0.5 second hold. When you want to turn it off, you have to hold it for 0.5 second again. If you don't hold the button long enough, it switches brightness modes. If you hold it too long, at 1.2 seconds it enters strobe mode. As a technician, I want a simple on and off click.

105 degree flexible head, magnetic tail cap, and square body allow you to point it almost anywhere
Very good throw for being a work light
Bright hotspot with a reasonable spill beam
Good all purpose light for outdoor use too
Battery level indicator

Light can be too bright at close range, especially pointed at metallic surfaces
Holding the switch for 0.5 second adds an inconvenience to quick use
Battery life is good, but for being 3400mAh, it seems like it should last longer (for comparison: LD30 on 150 lumens lasts 17.5 hrs, WT25R on 150 lumens lasts 11hrs)
No moonlight / ultra low lumen mode (1 lumen or less)
