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

ON/OFF
Tap
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.

Strobe
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.

Charging

  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. 

Warning
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.

    This is our second order of the UC35’s. We have purchased several (10-12) in total, only reason I’m giving them a three (3 star) is two of the UC35’s of my original order have already failed. We are hard on these flash lights, used daily (commercial construction). Just would have expected a longer life for a high quality brand at this price point.

      Hi Paul – I have asked someone from warranty to reach out to you as that should not be happening.

  2. Ashley S. (verified owner)

    Bought less than a month ago and worked great up until yesterday. Now it is not turning on 99 percent of the time and I have to take the battery out and put it back in and sometimes it will turn back on with that. Loved it at first but disappointed now

    Great flashlight once troubleshooting and everything tightened up. For almost $100 I expect it to work out of the box. The first hour or so I was ready to return. Intermittent light. No light.
    Regardless of what charger says give it multiple hours. Tighten all pieces.

    First impression wasn’t very good – pushing the output selection switch would cause mad flickering and the light would stay at its lowest level. Later on, the switch somehow fixed itself and it now works, but I am concerned that this is going to be a repeat issue and is a symptom of cheap electronics (something I have seen before with a $3-LED flashlight from a local store).
    The output selection switch is hard to find in the dark, especially with gloves on, and is not practical at all.
    My other concern is with the rubber cover for the USB connector. I fear that it would deteriorate over time as it normally happens with rubber-made stuff.
    The Turbo mode doesn’t seem 3x brighter than the High mode so I wonder if the specs are accurate.

      Hopefully the flickering doesn’t occur again – typically that only happens initially before a full charge of the battery. So I would make sure the battery has a full charge, but if the issue seems occurs again with a full charge, please contact the warranty/repair department for help.

    I truly loved this flashlight! I carry it everyday I go to work and use it daily, that is for the first two months. All of a sudden yesterday it quit working. Won’t even charge. Very disappointed in the longevity of this expensive flashlight.

      Sorry to hear that happened Jonathan. I’ll have someone in warranty email you.

    High is 25% weaker than the PD35 UE from 2014 of 460lm!

    So less usable at high, and can claim 40 lm more for Turbo which is limited to a few minutes!

    High should be more like 600lm. So the upgrade here is more about marketing 1000 lm rather than an improved flashlight.

    Disappointing

    it’s a decent light, but not great to me. the two brightest setting (1000 and 350) still not last long enough for me, the next one around 100 lumen is not bright enough for running on moderate technical trails. I need a light 1) compact 2) bright enough like 350 lumen 3) last for a whole night.
