Each time the light is turned on, the battery level indicator will automatically display the battery status for 3 seconds.

  • Green flashes: sufficient
  • Red constant on: poor
  • Red flashes: critical

Note: This only works on rechargeable LI-ion 18650 battery.


Intelligent Protection

The light will accumulate a lot of heat when it is working at Turbo mode. When the light is overheated up to 65 ℃ or above, the flashlight will automatically step down a few lumens to reduce the temperature; when the temperature is lower than 65 ℃, the output will gradually return to Turbo output level.


Low-voltage Warning

When the voltage level drops below the preset level with the light switched on, low voltage warning will be activated automatically, then the battery level indicator on the Functional switch will flash red to remind battery replacement or charging. The flashlight is programmed to step down automatically to a lower brightness level until Eco output is reached. To ensure normal use, the flashlight will not turn off until the battery level runs out or once the battery over-discharging protection activates. Note: This only works on 18650 Li-ion battery.



The battery holder features charging function with a standard Micro USB port.

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 flashlight will not be used for an extended period, remove the battery, or the flashlight could be damaged by electrolyte leakage or battery explosion. 


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 flashlight's performance as dirty contacts may cause the flashlight 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. 

C: The battery protection board is in a protective state and unable to free from it. 

Solution: Take out the battery holder and replace it, or replace the batteries. 


If the above methods don't work, please contact your authorized distributor.

Fenix lighting repair service was amazing! I have two of these TK35UE flashlights and just love them. I had dropped one of them and it stopped working. Contacted customer service and an RMA number for return.
Holy Crap this must be the fastest repair ever - Mailed it on the 12th and got my now working flashlight back today the 20th. From San Diego to Monticello, AR and back in 11 days. Thanks to everyone at Fenix lighting for providing excellent service - Jim

I have the earlier version of this light that is only slightly different. I have had it for at least 3 years and it has performed perfectly. I keep it on my nightstand with my handgun for anything I might need to light up without pointing a weapon at it. I take it hunting every time I go and it gets banged around pretty good. I even dropped it off of my ATV at about 15 MPH and other than a little road rash it was fine. It is extremely bright with a rather wide beam and has great battery life when using good batteries. I would not hesitate to buy another if something happened to this one. I have several of the high-quality and somewhat expensive brand name tactical style lights and Fenix definitely holds their own against any of them and usually for less money. Thought I would leave this somewhat long-term review while I was here registering my new Fenix light.

William Graves

Ur advertising isn't good at all. U can't read that it doesn't come with any batteries. Until it actually arrives. I haven't been able to use it.

Bill Bedini

These flashlights are the best hands down. This recent purchase was a gift for someone. If you buy one you will love it.

Dan Bott

This is a high quality, excellent semi-tactical flashlight with a lot of power behind it. Definitely worth the cost.
