Operation Instruction

The tail switch is tactical switch, the side switch is 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 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 to Low brightness level. 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.

    Been using this torch a little over a month now. I purchased a couple usb rechargeable batteries with the light. I have to say I love this flashlight. The various outputs make this an all around winner. It is very versatile. I can use it up close to read something and then go into turbo mode to see across the yard. I use it every night to check for skunks in the yard before I let the dogs out. Love the rechargeable batteries…beats using CR 123A’s. I recommend this light.

    I always searched of the highest output I could find. After experience with a few “high output” flashlights I realized that the function of the switches is much more important. For instance my last light had to cycle through several modes with a single switch before returning to the original setting. The Fenix TK15UE with the side switch for function modes and the tail switch with memory taught a great lesson. Use the memory to turn on to where you would most likely need it then go to the mode you perhaps need in a given situation: turbo, strobe or low light. This flashlight is intuitive and that makes a ton of difference for me. Brightness? It has all I could want. I can now distinctly see the difference between a hunting dog and a coyote at 75 yards.

    I originally bought this light via Amazon in 2010 when it was just the TK15 (no UE). I have used it in pretty terrible conditions over the last 6 years and didn’t have a problem. I noticed that when I used less than stellar rechargeable batteries the charge would only last about one 8 hour shift. I discovered only about six months ago that Fenix had their own rechargeables. I switched to their 3500mAh batteries and I go a week with the same battery and never worry about it dying. After all the abuse my light took, it finally died on me for good about two weeks ago. I contacted Fenix customer service and they asked me to send it in. Today I received a brand new light in the mail. I cannot say enough how much I think of this company to send me a new light after all the years and hours of run time on my old light. No questions asked. I sent it, they sent a new one. I legitimately like this light. I am currently in the market for an additional light and think I will try the TK16. I like the set up on my TK15. I pretty much keep it on the high setting. I have used strobe but rarely as the location of the mode switch on the TK15 makes it a little difficult to change modes while running or on the fly. That’s the main reason I leave it on the high output setting. On my original I didn’t have any issues with failure to turn on or anything until it finally took one too many blows. I cannot recommend not only this light but this company. I’ve seen some bad reviews on a couple different products from people that say they didn’t receive assistance but I find that hard to believe as I was emailed back by customer service immediately. Seriously love this light and this company.

    This light is so awesome, it crushes the others and I’m so glad I decided to buy it. I’m a truck driver and I use it everyday. I’m at work by 2 am and in the dark to hook up and inspect tractor and trailer every morning. The other guys are still using the cheap aa battery lights and are always talking about how bright mine is. It’s so fun to come over to them and shine my light to help them get ready. The price might seem high but don’t worry because this thing will last forever and it’s rechargeable batteries will pay for its self in no time. It’s also a blast while we were on vacation at the beach. We would take the grandkids out at night looking for crabs and this light blows everyones cheap led flashlights away. The kids even notice how much brighter this Fenix light is. I’ve had mine over a year and it’s still going strong on the first set of batteries. I usually charge each of the batteries once every other week. I have 2 so I always have a charged battery ready to go in case I need it. Bottom line: this light will possibly be the best light you ever own. You will not be disappointed, so tell the wife this is a safety investment and just get it.
