Additional Features of the Fenix TK15UE – Gray

*Due to intelligent over-heat protection, the runtime of the Turbo brightness level is the accumulated time.

  • Uses Cree XP-L HI V3 LED with a life span of 50,000 hours
  • Compatible with AER-01/AER-02 remote pressure switch
  • Digitally regulated output maintains constant brightness
  • Reverse polarity protection, to protect from improper battery installation
  • Anti-roll and anti-slip body design
  • Tactical tail switch for momentary-on function
  • Functional side switch for output selection
  • Made of durable aircraft-grade aluminum
  • Premium type Ⅲ hard-anodized anti-abrasive finish
  • Toughened ultra-clear glass lens with anti-reflective coating

The tail switch is a tactical switch, the side switch is a functional switch.


Tap the tactical tail switch to momentarily turn on the light, release it the light will go out.

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

Output Selection

With the light on, single-click the functional switch to cycle through Turbo→Low→Mid→High.


With the light on, press and hold the functional switch for 0.5 seconds to enter into the Strobe mode, click once again to return back to General mode.

Intelligent Memory Circuit

The flashlight memorizes the last brightness used in the General mode, the next time it is turned on, it will recall that previously used brightness level.

Over-heat Protection

The flashlight will accumulate a lot of heat when it is working at Turbo. When the light is overheated up to 65℃ or above, the flashlight will automatically adjust the output in a stepped way to prevent the light from overheating.

Low-voltage Warning Function

If low voltage is detected, the flashlight is programmed to downshift to a lower brightness level until Low brightness level is reached. When this happens at 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 until the battery runs out completely.

Battery Replacement

Unscrew the tail cap to insert the battery with the anode side (+) towards the light head, and then screw the tail cap.

Usage and Maintenance

  • Disassembling the sealed head can cause damage to the light and will void the warranty.
  • Fenix recommends using 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 one-half 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:

Reason A: The batteries need replacing.
Solution: Replace batteries (Please confirm the correct installation of anode and cathode).

Reason 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 refer to the warranty policy before contacting your authorized distributor.

    I got this light a few years ago to be my go-to light for camping. My son needed it for his security job at night. So I let him use it. Today, 13 months after he passed away I found this light under the seat of his car. I could see that it was used and abused. Dropped,dragged or stepped on I do not know but I do know that it works just as good now as it did when I got it out of the box. This is a good light.

    The light is great. I took the hex ring off it was too bulky and the lights wrist strap gets caught on the velcro of the pouch causing it to fray. A better pouch/belt clip would be awesome or just do without the strap.

    BEST flashlight I have ever owned! LOVE the side-mounted mode button. Makes switching brightness levels during use very easy. Beam is very strong, and focused just right. Not to narrow, not too wide. I was amazed at how potent it can be at night at full power! Gray finish looks absolutely fantastic. Construction is solid, and feels like quality all the way around. VERY happy that I replaced my dead Nitecore with this one.

    These are my favorite light of the bunch. I like the on/off button separate from the light brightness, the size, the max lumens, the tactical-ness. I presently own three to four of this model and expect to get a few more. Fantastic light.

    This is my second Fenix light, and I’m very impressed. They gray finish just looks amazing. Understated, but really nice looking. Beam is tight and uniform, and very bright. White light, great distance. Built much better than the cheaper lights I own. Very happy with this one!

    This one is definitely not my first flashlight, I’m kinda a junky when it comes to quality lights and collections. The cadet grey is absolutely gorgeous, finish is top notch , the light performance itself is outstanding, plenty of punch when it comes to beam distance in a light of this size , nice hotspot with plenty of side spill , the cool white beam is very pleasant and not harsh at all as I am more of a neutral white preference but the cool white is very pleasant .
    The UI is very easy , a bit big if you EDC in your jeans pocket ,The PD35TAC or the new UC35 might make a better overall EDC , Overall the TK15UE is very much worth getting .. Huge props to FENIX ..

    This light is the best, hands down, I have ever owned. I work nights, I use it on all four settings. The low setting is great for reading gages and making inspections up close. When I’m on days, it comes in real handy getting a good look in a dark warehouse. When we go camping, I take it along with my E21 and LD22. I will never be without one of my Fenix flashlights!
