Operation Instruction

On/Off Operation
Press the tail switch gently for momentary lighting or until it clicks to activate and lock the UC35. Press again to turn the light off.

Mode Selecting
With the light on, press the side switch to cycle through five different brightness levels in the order of Turbo→ Eco →Low → Medium → High.

Strobe
Press and hold the side switch for 1 second to enter into Strobe mode. A single press on the side switch will return the flashlight to general lighting mode from Strobe.

Intelligent Memory Circuit
The Fenix UC35 memorizes the last brightness level used in the general mode, but it will not remember the Strobe modes. The next time you turn the flashlight on, it will activate the last brightness level you selected.

Turbo Output
In Turbo output, the LED runs at the highest brightness and discharge rate. Use of high quality batteries is recommended for peak performance. As a high-performance light, the UC35 accumulates significant heat while at Turbo output. To protect the light and user, the UC35 automatically drops down into the High brightness level after running at Turbo output for about five minutes. If further Turbo output is needed, reset the light with the side switch. Be advised that prolonged Turbo output may reduce the UC35’s life span or cause permanent damage to the light.

High Output
To protect the light and user, the UC35 automatically drops into the Mid brightness level after working in High output for about 30 minutes. If further High output is needed, reset the light with the side switch.

Low-voltage Warning Function
When the voltage level drops below the preset level, the UC35 is programmed to downshift to a lower brightness level. When this happens in Eco output mode, the flashlight blinks three times every five minutes to remind you to replace the battery.

Charging

  1. Press the tail switch to turn off the flashlight. Then connect the USB cable to a USB power adapter (sold separately), and remove the anti-dust plug in the front of the UC35 to reveal the charging port and plug the Micro-USB end of the USB cable into the light’s charging port.
  1. Press the tail switch to start the charging process. And the indicator light below the mode switch turns red to indicate the charging process has begun. The indicator turns solid green when the battery is fully charged. It takes about 5 hours to fully charge a 3400mAh Li-ion 18650 battery (lab-tested by Fenix using ARB-L2S rechargeable Li-ion battery)
  1. Once charging is completed, press the tail switch to stop the charging process and disconnect the USB cable from the light and be sure to secure the anti-dust plug cover.

Note: Please recharge a stored UC35 every four months to maintain optimum performance of the battery and maximize charging levels.

Warning:

  1. Please do not mix batteries of different brands, size, capacity or type. Doing so may cause damage to the flashlight or the batteries being used.
  2. Do not use the UC35 flashlight to charge the banned batteries, or it may cause explosion.

*18650 Li-ion batteries are powerful cells designed for commercial applications and must be treated with caution and handled with care. Quality batteries with circuit protection will reduce the potential risk for combustion or explosion but cell damage or short circuiting are potential risks the user assumes.

** The UC35 can be powered by using 18650/16340 LiFePO4 rechargeable battery, but using the flashlight to charge them may cause damage or even explosion to the battery. To avoid the potential danger, please do not charge these two kinds of batteries.

Battery Replacement
Unscrew the tail cap to insert the batteries with the anode side (+) toward the light’s head, then screw the tail cap back on.

Usage and Maintenance

  • Please don’t disassemble the sealed head, doing so can cause damage to the flashlight and will void the warranty.
  • We recommend the use of high quality battery. If the flashlight is not to be used for an extended period, remove the battery, or the flashlight could be damaged by electrolyte leakage or battery explosion.
  • Due to the momentary-on tactical switch, the flashlight may be accidentally activated when stored, transported or placed in a pocket. Unscrew the tail cap one-half turn or take out the battery to avoid unwanted operation.
  • The O-ring may be worn out after using for a long time. If this happens, please replace the O-ring with a new one to keep the flashlight properly sealed against water.

Please clean the contacts of your light from time to time, especially if the light flickers or doesn’t light up. There may be several reasons for a flickering or not working light:

Reason A: The battery needs replacing.
Solution: Replace the battery (Please confirm the correct orientation of positive and negative ends).

Reason B: The threads, PCB board contact or other contacts are dirty.
Solution: Clean the contact points with an alcohol soaked cotton swab.

If the above methods don’t work, please refer to the warranty policy.

Product Warranty
We will replace products with manufacturing defects within 15 days of purchase and repair a light free of charge within 24 months of purchase if problems develop with normal use; if repair is required after 24 months from the date of purchase, we will charge for parts. The total repair fee is dictated by the cost of the replaced materials.

Product Registration
We kindly suggest that you register your product on the official website of Fenixlight Limited (www.fenixlight.com). You’ll receive an extra six months of warranty coverage once you have successfully registered. By participating in an optional customer survey, you are entered in a drawing for free Fenix products.

Warning
UC35 is a high intensity lighting device capable of causing eye damage. Avoid shining the light directly into anyone’s eyes.

    I’ve had this light for about 6 months now & I can attest to that fact that it is durable. I’ve accidentally dropped it down a flight of concrete stairs and was gold to see that nothing was broken. I like the Eco Mode for use in the middle of the night and the turbo mode when I’m out in an open area like a field in the early morning or late hours of the day. It has great throw distance. More than most urban situations require but also great if you live on a ranch. Plenty of those here in Texas.

    I have a UC35 that I have carried for 4 years. It has taken a drop of 85 feet onto a steel floor and never even bilked. It has been drop so many times that I lost count. It has been in oil based drilling mud and in water and has not failed. I droped it about a 2 months ago and the light went out. It will still charge the battery so I put in a POD35 and it also performs as well as the UC35. I have 2 PD 35s and will get another UC35. This is the toughest flash lite that I have ever had. I carry a flash light in my pocket 24/7. absolutely never with out it.!!!

    Curious why my Fenix UC35 flashlight in which I’ve been using another brand’s 2600mAh Li-Ion 3.6v 9wh won’t even turn on with the GoalZero 18650? Packaging says they come precharged and the charger says they’re fully charged as well.

    Battery life doesn’t seem to last long, within the hour and a half the red light starts blinking and dims the light to eco which practically is as if no light was on. Purchased four months ago and flashlight doesn’t turn on anymore. Thought it was the battery, ordered a new battery and still doesn’t turn on. Tried charging it for an hour still nothing. I’m a day away from one of my biggest jobs and I feel like I’ve been let down. I’ve had another competitor’s brand 6 years strong never had any issues whatsoever. Sorry Fenix.

    I work ramp for a major airline and always have this flashlight in my pocket. Absolutely love it and the small size and how powerful and bright it is. So many pilots have seen me using it and asked where to get one. Highly recommend for every day carry.

    Absolutely LOVE this light. I volunteer as an EMT and this light stays in my back pocket all night long. Walking into a home with no lights? No problem. Bounce this light off the ceiling on Turbo mode and the entire room lights up as if I switched on a 60W bulb. Need to find that “one down” hiding in the bushes at 2:00 am? This will flush them out. Need some extra light while extricating someone from a vehicle? This will come in handy.

    I love the small form factor that allows it to fit in my back pocket without impeding my ability to sit down. I love the fact that it is rechargeable so I’m not worrying about finding batteries each shift. It’s a solid case that protects it when I drop it on the engine room floor. The clip is strong enough to prevent it from easily falling out of my pocket and won’t break off. All around, it is a fantastic light.

    I am a building inspector and I sometimes need to cut through shadows in the nooks of framing even when daylight is filling the room. The beam from the UC35 reaches far into the rafters that are sometimes 15-25 feet away. At night, this flashlight casts a stadium like beam, truly remarkable! Since I use it every day, I never worry about finding batteries, I love the USB recharging system. I’m really pleased with the build quality too! Nice job Felix.

    I do not have enough good things to say about the UC35 flashlight. I have had my light for over a year. I carry it every day, I use it for work as a pressman, mechanic, and general handyman, it is bruised and battered the finish on the tail cap has worn off from sitting on it against cement, it has suffered drops on occasion, never failed to work the glass lens looks like it did when brand new (something i couldn’t say about the minimag pro plus after 3 weeks of use). The rubber boot on the tail cap is still intact even after a year and the switch it self works flawlessly. The original battery still provides plenty of life after 150 charge cycles. The brightness is still very competitive with other brand new lights on the market ( I would love if they did an update with a more powerful emitter like the xhp35 or xhp50) but this is plenty of light for now. A few things to keep in mind about this light is the beam distance isn’t that far at 200 meters compared to other lights. The hot spot is huge so it is awesome for up close work like working on a car. 9 of my friends all have one now. You wont regret this light.

    I needed a smaller light for work. Something I can keep on my belt that is rechargeable and bright. I found the UC35. I love the USB charger. Very bright light with several settings. Great light for work or camping. Each charge lasts for a long time. The light seems to cut out sometimes while I am using it, but not sure why. Overall a very good light and I would recommend.

    I have owned the UC35 for about three months now. I was primarily interested in the USB recharging port and the powerful 18650 cell that powers the unit. I don’t use the USB port all that often because it never seems to run out of juice. I seems to be quite rugged and weatherproof. The adjustable beam brightness is very handy. The beam throw on the highest setting is very impressive. I feel it is a bit long in my pocket for EDC, I use it for a bed stand light. I give it a thumbs up.

    I bought this light on a whim about 6 weeks ago. I have always used maglights and other larger flashlight but this is my first EDC light and I love it. I wish I could get a tactical bezel for this light but other than that I love it. I have too many different charging cables so, the fact that it is rechargeable with a micro USB was the main reason I bought this light instead of one of your competitors. Great job. I am now looking to get a light like this for my son.

    I love this light! I would like it better (almost impossible) if it started in strobe and then could be advanced to solid/intensities using only the tail switch. I have had it a year now and will be buying a couple more of them.

    My boss bought a bunch of these for us a year ago for Christmas. I love it! Unfortunately the one downside is the Velcro holster failed, and I lost my light in 3′ of snow while pulling a man out of a wrecked truck in the mountains. The night before I had said to my boss that I wanted to have a leather holster made for it.

    This is a fantastic light. I work night-shift law enforcement, and I use it constantly. The lumen power held in this lightweight body is perfect for my uses, and cuts ounces on my belt. I especially like the ability to blast full power during tactical operations, or button down for general use. My only negative is re-charging. The cable never seemed to fit quite right, and had difficulty staying in charge-mode. Eventually the cable charge port broke, and I’m now resorting to standard batteries. Other than that, I highly recommend!

    I have had this light for 2 years now. I really love this flashlight. The only problem I have is getting it into the charge mode. Most likely it is me. You must hold the switch to get to charge mode. I have used this light for SAR and CERT (Community Emergency Response Team) in both training and ops. It works great for these ops. I do carry backup 123a batteries but as of yet never had to use them. This flashlight is well worth the money.

      Thank you for the comment James. In order for the UC35 to start charging, you must 1. plug cable into port 2. switch tail light on begin charging. Once you switch the tail light, you should see the UC35 charging light turn on. You are correct that you need to turn the switch on to get to charging mode!
      We are so glad to hear that UC35 has been a great light for Emergency Responses!

    I would rate this 10 stars if I could. This is the best flashlight I have EVER owned. I have used and abused it for over two years and it’s completely solid. It has gone on multiple adventures to all parts of the world and it holds up beautifully. This is a work horse and I cannot imagine how I got along without it. My wife loves it too and I will be ordering one for her.

    I love this light. I would recommend to anyone and everyone who needs a rechargeable flashlight. Also I love the regular battery feature so I keep in my truck or backpack a couple of those batteries so when the charge goes out (which it rarely does) I can throw one of those bad boys in there and keep on working. If you are looking for a great flashlight but don’t want to pay hundreds of dollars for it this is the flashlight to get.

    Awesome light! Battery life has been great, haven’t run it completely out yet between charges. The USB port is a little snug, so be careful when plugging it in. I do like the fact that there isn’t a separate charger. I purchased mine about 3 months ago and I think I paid $80… not too excited about the $40 jump in price at $116.
