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

Tap the tactical switch to momentarily turn on the light; release it and the light will go out.

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

Output Selection
With the light switched on, single click the functional switch to cycle through Turbo→Moonlight →Eco→Low→Med→High.

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

Boot-up Battery Level Indication
Each time the light is turned on, the battery level indicator will automatically display the battery status for 3 seconds.

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

Note: There is no indication when CR123A battery is used.

Intelligent Memory Circuit
The light memorizes the last selected brightness level on General mode. When turned on again the previously used brightness level will be recalled.

Intelligent Protection
The light will accumulate a lot of heat when working at Turbo mode. When the light is overheated up to 60°C or above, the flashlight will automatically step down a few lumens to reduce the temperature; when the temperature is lower than 60°C the output will gradually return to Turbo output level.

Low-voltage Warning
When the voltage level drops below 3V, the flashlight is programmed to downshift to a lower brightness level until Moonlight output is reached. When this happens in Moonlight mode, the battery level indicator will flash red to remind you to replace the battery. To ensure normal use, the flashlight will work until the battery runs out or the battery over-discharging protection activates.

Note: The low-voltage warning only works with rechargeable Li-ion 18650 battery, not with disposable CR123A’s.


  1. Turn off the light. Plug the USB side of the charging cable into any USB power supply. Uncover the dust cover of the light, and plug the Micro USB side of the charging cable into the charging port of the light.
  2. The battery level indicator displays red while charging and turns to solid green when charging is complete. The normal charging time of the included Fenix ARB-L18-3500 is about 3.5 hours.
  3. Once charging is completed, be sure to remove the charging cable and replace the dust cover to protect against dust and foreign objects.
  4. Recharge a stored light every four months to maintain optimum performance of the battery.
  5. Only Low output can be used while the light is being charged, but charging time will be prolonged.

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 battery needs replacing.
Solution: Replace battery (Ensure battery is 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.

    Fenix has found their way for all my flashlights and head lamps. Stood up to a 8 story fall and multiple swimming events. A light that can take all abuse dishes it’s way even unreasonable. Bests lights I’ve owned.

    Great built flashlight with wonderful battery life, intense spot, great throw, and great size. My only complaint is the brightness adjustment button should be lit all the time as it can be quite difficult to find in the dark. Either have the battery indication light always on or texturize the button to better stand out. Other than that, great flashlight.

    Awesome light – I work in the automotive industry and this light is changing the game – its impact resistant and it already fell into a bucket of coolant and oil mixed together and still works great – the seal needed to be changed and the flashlight came with extras. This is by far the best flashlight on the market. This is my daily carry light and as far as I am concerned there is no better light on the market. 4 weeks of use with out recharging holly cow. I will be purchasing head lamps and more lighting from them – as an Alaskan resident central to northern region – arctic condition testing proved to be very successful – this lamp keeps your hand warm – its so bright and creates heat and may be a downer if you live in southern California and the summer and your trying to look into an engine compartment but would still be worth it., I highly recommend this light to anyone but specifically to those in military police / fire / automotive or anyone who needs to rely on their flashlight daily this is the one for you.

    An overdue replacement needed for my profession. Ordered this with 2 extra 3500U batteries and the green and red filters. I just wish this came with the USB rechargeable battery. Well worth the price!

    As always the product quality and performance is top notch as with all Fenix Products. I have been purchasing for Years and now as a Fenix ambassador am able to be even more impressed. These lights were needed for a US NAVY function and the turnaround and shipping was the same day highly recommended.

    Wonderful lights! I have several PD35 models used for work and EDC… I like the 4 mode selection on the Fenix lights as well as the streamline body so it doesn’t interfere with movement and working in tight spots, having it clipped to a pant pocket. The new UC35 rechargable light is a great improvement and still maintains the high lumen output… Great company and great products! Thank you FENIX!

    This was a great addition to A Special military event and as a Fenix Ambassador I greatly appreciate the one day turn around and fast shipping that fenix provides. Will order again for next event. All attendees Loved the Fenix quality.

    So far so good, only had my light for few weeks. I like the size which easily fits in pocket but has the brightness of something 10 times the size. I would recommend this brand to anyone so far. If problems arise I am confident that fenix will handle them professionally and quickly.

    Great light! As a home inspector I rely heavily on my flashlights and this one delivers. Use mostly on high but Turbo really lights things up when necessary. My next Fenix will have a flood/spot option and I’ll be good to go.
