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.

    Product is wonderful! Very satisfied with its performance. Very bright and well made. However dealing with Fenix customer service was horrible. After the item was ordered, it took more than 4 days just to get a tracking number as the item almost took a week to ship out. I will not be buying anything directly from Fenix’s website anytime soon!

      Glad you love the light, but sorry you had a long delay in receiving it. In reviewing our records, the date of your order happened to occur when a massive storm hit the town where our warehouse is located, resulting in several days of power outages. I know that the weather, combined with the power outages, delayed many of our shipments both in and out of the warehouse. Again, we apologize for the inconvenience.

    Nice power and longevity in a relatively compact package. Would be slightly better if the charging port cover would stay put.

    I think this flashlight with1000 lumens is perfect for what I needed to do at work. However I gave it a 4 rating because I would like to see this flashlight have a zoom in and zoom out on the stream of light itself. Other than that I work nights and it does everything I needed to do, it’s a solid flashlight. I love the fact that I could charge this flashlight via USB that is the best feature.

      Hi Denise – sounds like a bad battery – I’ll have warranty reach out to you.

    The UC35 is a great flashlight, just as bright as the UC30 I have used for some time. The addition of a tail switch adds functionality. The brightness level button is a bit more difficult to find in the dark than the one on the UC30. I am trying aligning the pocket clip with the button to give a reference point. The rubber USB port cover is more difficult to close and seal properly. The cover on the UC30 is better, in my opinion. Aside from these issues, I am pleased with the light.

    Well built light and no problems so far. Super bright. The belt pouch could be a little better though. It’s already showing wear marks after a couple weeks. Also USB charger port cover is way to tight and nearly impossible to perfectly close.

  15. Joseph (verified owner)

    Good light. very light weight for pocket carry.

    CONS: the selector for the modes is a bit hard to find by feel alone. should be more of a stub sticking out. also near impossible to change modes with heavy gloves on. PLEASE FIX THIS IN NEXT EDITION.

    WANTS: Perhaps a sacrificial cover to place over the lens for those of us that use during maintenance etc. scratched lens is not possible to just change out. Also perhaps a version with adjustable spot to flood. This light is more beam centric/spot than most other lights in its class.

      Hi Joseph – one way to locate the switch is to turn the belt clip so that it lines up with the side button.

  16. Wendell (verified owner)

    Right pricy but really bright. The dark runs from it.

    Good service. Good product. But The full mode in light isn’t holding for as long as factory suggests. 1000 lumens are getting dimmed after 4-5 minutes of use even with fully recharged battery.

      Unfortunately the factory website has had problems with registration, however, when you buy through us you are pre-registered through your serial number.

    Unfortunately my flashlight was giving me trouble as it would show half charged after being taken off the charger and turned on. And the modes flickered ehen selected with the full battery. Even one of the replacement batteries did not fix the flickering. Finally got another light at REI and it was OK, so now I have a functioning light. Love the throw, but I would love a more floody small flashlight as well.

    This is a very nice light. Functions well and compact enough to carry daily. I gave a 4 as I do think it is a bit over priced but bought it anyway.

    I’ve had this light on my hip for about 2 weeks now using the included belt holster. Each level of brightness is useful, and has been used. The size is perfect.
    If I can’t see it is hard to index to the output selector button. I moved the clip to underneath to assist finding the output selector button. There are grooves on the body that can help index too.
    The tail button is longer than the guard so you cannot stand it up.
    An odd this is I charged for more than 4 hours and the led was still red. I tried the Samsung phone charger and an Anker intelligent iQ charger. So I don’t trust if I’m getting a full charge. I may get external charger.

      We will have someone from our warranty department contact you about the charging LED to see what’s going on.

  22. Josh (verified owner)

    Small and bright with a nice indicator light on the side that tells you the charge level. Great for recreational use. The little smooth side button is hard to find and is frustrating to adjust brightness in the dark. Not tactical.
    If it had a better design, to locate the side button by feel, it would be the perfect small light. Nice and durable and, other than the side button, I like the design. Recharging it is easy and convenient!

    Flashlight is a bit larger than I expected but is very well made. The dispersion of the beam and the color rendition are very good.

    The UI for the strobe is terrible. It requires you to turn on the light from the tail switch and then press and hold the SMALL switch on the side for a second or two to activate the strobe mode. Not very practical for a self-defense strobe feature. Too bad they couldn’t (or didn’t) enable the strobe to operate by pressing AND HOLDING the tail cap button in for, say, 2 seconds. This would keep the strobe mode active until the tail cap switch was depressed again.

    I am also a bit leery of the long-term life-span of the rubber seal around the charging port. Time will tell.

    The holster for this light is the cheapest and flimsiest of all of the flashlight holsters I have ever owned. Additionally, with a light this long, it’s a bit uncomfortable when sitting down. A horizontal carry option would be more comfortable. I have actually done this with a couple of strips of double-sided velcro.

    Quality construction with waterproof charge port! Comes with high capacity 18650. Two reasons why it didn’t get 5 stars; Can’t stand on its tail and it’s very difficult to feel the side switch. All in all this is a very solid light…

    light works great and i use it primarily on “high” mode to walk my dog every night. with the occasional switch up to turbo if i think i see some sort of critter. i use it 20-30 minutes per night and charge it when the light starts showing solid red. this takes about 8 or so days to get to. i really like the turbo light output but the unit heats up quite a bit in your hand in that mode. also i feel that 1k lumens is overkill for walking the dog in the suburbs. all in all it is a fantastic light!

    Great light except for the second button. When I pull it out of my pocket I can’t find the button. Their is no reference on the body as to where the button is. That being said the tail button is fantastic! It’s easy to operate as it sticks out enough for my thumb to push.

    60% reliable so far. It doesn’t always fire up when I press the on/off switch. I will rotate the crown and it lights up. Also, occasionally, the strobe works for only about 2 seconds then it shuts off until I once again rotate the crown. Not good.

    This is one of the best all around lights I’ve ever used to date – I work in LE and use it as my backup light – the 1,000 lumens is enough to use as a flood light & is excellent for building searches & room clearing. The mid-range lumens are excellent for vehicle/person searches. The 1 lumen is excellent for when I drop things in the car and have to find them on night-shift. In the off-time (I’m an avid outdoorsman) and this becomes a safety light on road trips and for anything outdoors related it can’t be beat. Again, the 1 lumen was a winning selling point for me because it is SOOO useful.

    Pros: Variable lumen outputs in well-thought-out increments.
    Pros: Durable & reasonably “waterproof” (so far I’ve never had issues with water failure)
    Pros: Huge fan of being able to use 123 batteries and the 18650s interchangeably

    Cons: For all the Fenix Lights that have the rubber tail-button, WHY can they not design it so the button does NOT extend beyond the guard so it can be stood on it’s tail.
    Con’s: Probably my biggest complaint, though I really like the side switch – it’s a bit small and when working in the dark (duh) it’s difficult to locate. I think an improvement would be either a larger, easier to find button, or a permanently illuminated side switch so changing the brightness would not be a challenge.

    All-around HIGHLY RECOMMEND.
