The light will accumulate a lot of heat when used on Turbo output level for extended periods. After a 3-minute work on Turbo, it will automatically downshift to High output level to reduce temperature. Turbo can be reselected if needed, but service life could be shortened or the flashlight could be damaged permanently.

When the voltage level drops below than 3V, the flashlight is programmed to downshift 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.

Unlock: with the light locked, 2 continuous single clicking within 0.5 seconds on the side switch . The light will be unlocked and activated on last used brightness.

In locked status, clicking or pressing the side switch will activate 2 one-second blinks on Low to indicate locked status.

  • Green light constant-on: saturated, more than 85%
  • Green light flashes: sufficient, 85%-50%
  • Red light constant-on: poor, 50%-25%

  1. Plug the USB port of the charging cable into any USB power supply. Uncover the anti-dust cap and plug the Micro USB side of the charging cable into the charging port of the headlamp.
  2. If the battery level is fairly sufficient, the charging indicator displays green to indicate unnecessary charging. Or the charging indicator will display red while charging, and will turn to green when fully charged. The normal charging time of the built-in Fenix ARB-L18 2600 is approximately 3 hours from out of power to fully charged with the light off.
  3. Once charging is completed, be sure to remove the charging cable and replace the anti-dust cover.
  4. Recharge a stored light every four months to maintain optimum performance of the battery.
  5. The flashlight can only be used on Low output when charging, but the 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 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 batteries need 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.

    This model has the same impressive lighting capabilities as Fenix’s most popular tactical models, but without the tactical tail switch. Instead, one button on the side controls the On/Off as well as all of the brightness selections. I do not engage in any sort of tactical activities, nor do I have any reason or desire to hold a flashlight face-down in my fist, so I find the UC-30 to be the most capable and convenient model Fenix offers.

    I had this light until I lost it about a month ago. It was perfect for my work, so much so that I ordered another one after exhausting all possibility of finding it. This light was perfect for me to light up the inside of machines without having to go Turbo. Stood up where I needed it to and was small enough to not be in the way. I just need to take better care of it so that’s a user error! The ability to recharge it using a USB cord which I kept with me was an awesome capability for me since I travel to service equipment all over.

    Well one of them was hijacked by my wife as her purse EDC, the other is in it’s intended spot. These are great lights, they do get hot on full beam after a minute or so, but I’m thinking that’s normal for a 1k Lumen light. First high power professional lights for us since my duty 6P from 1993.

    I have gone thru many FLs. I called the company and a person in warranty answered. I asked him for guidance for a simple FL to use. Knowing it wasn’t a warranty issue he still helped by guiding me to this UC30. I really do like the simplicity of it. Wish it came with a clip is my only suggestion. Fenix hires good and helpful people that go beyond their normal job responsibilities and that is awesome …Thanks Fenix for producing a high powered, but simple to use product.

    I dont understand why people are complaining about this torch turning on whilst in their pocket/holster? That is what the lockout feature is for, you have to rapidly double click the button then the torch flashes twice to let you know its locked. Repeat the process to unlock, i can’t see how it would be possible to double click the small button so fast that it unlocks the flashlight when its on your belt/in your pocket. I love this torch, incredible brightness and throw for such a compact size, excellent Fenix build quality plus its rechargeable.. all my friends who have seen it are amazed at how bright it is.. bargain for the price! Highly recommend it.

    Brightly illuminates my backyard when I go out to check at night. Bright, portable and handy flashlight. Five levels of brightness plus strobe are good options for brightness or battery power for longer lighting depending on the requirement of job at hand.

    Fantastic! My second Fenix light and even better than my last one. I use this at home as an emergency light or when we walk the neighborhood at night. Easily lights ups houses six ahead of us and the road . I have had my mom buy one to keep in her kitchen as well. Highly recommended

    Fenix UC30 came in the mail today.
    Initial impressions: Very well made like all Fenix products. What I like and why I bought the Uc30 is that you can recharge it with a usb cable.
    In the box it brings a spare o-ring, a nice thick charging cable (which is great to keep in the car), carrying pouch, and two extra usb port covers. Easy to use and it turns from red to green when charged and includes an 18650 battery. Overall great value.

    As a Home Inspector, I use a Fenix TK35 Flashlight and Headlamp on a daily basis. I would use the TK35 for my night time dog walks. I live on the border of a County Park and we have a lot of wild life in the area including Coyotes, possums, armadillos, and the occasional lose dog. I would use the TK35 to make sure the walk went safe.

    I purchased the UC30 as smaller alternative and for the convenience of the USB charging feature. As well as allowing me to keep the TK35 in my inspection tool bag at all times. No need to remember to pack it in the morning.

    This is a great alternative. It is smaller and still gives me the lighting power to check out areas while walking the dog. I have not yet run the battery down, and charge in once a every week or two.

    Great Value and easy operation

    Bought the UC40 flashlight in January 2015 and it’s only just died now, so I’m deciding whether to get the lighter weight RC11 (as I put the torch in my mouth, being a mechanic needing both hands at times) or the similar UC30. Overall very happy with the UC40, only minor issues is the weight for when it’s in my mouth and the charging port began playing up a bit, probably because I didn’t faithfully fit the dust boot back after charging each time.

      Michael, thank you for the feedback. The RC11 would give you a magnet on the back so you could have it hang on the hood of a car or something similar. The RC05 or RC09 would also work great for you!

    Had it for a couple of months and it is the best flashlight I ever had. Would highly recommend it. Surprised with the brightness as well as battery life.

    I’ve had this light for at least a year and it’s one of the best rechargeable lights I’ve ever owned. It holds a charge for quite a long time. Mine was in my backpack for several months without being used or charged and when I got it out, it was still charged and super bright and ran for quite a while before needing to be charged. I own about 10-12 different Fenix handheld LED flashlights and they are all great quality and very dependable and ready when needed. I usually buy two or three new Fenix brand flashlights every year and have always been pleased with their products.

    This is a great light for my bike and all round use! The beam pattern is great for the bike and medium power is plenty. The bike mount fits lots of handlebar sizes and has a quick release but I wish the nuts were captured so as not to get lost.

    Last year I got the UC40UE for Christmas. This year I got the UC30. This one is basically the same flashlight as the 40. There are minor differences, including a shorter length, a very slightly shorter runtime, afferent charge point, and a glow in the dark switch. Its also a fantastic light, and maybe a better choice than the 40. Seeing as how the runtime is so slightly shorter, it doesn’t matter. I like the GITD switch, as the non GITD switch on the 40 is kind of hard to find in the dark.
    I do like the tail cap charge point on the 40 better, this one charges from the side.

    As with the 40, my only real gripe is the extremely low-profile switch. They should make it bigger, so it can easily be felt, even through gloves.

    Either way, I’d definitely recommend it!

    Although it’s approx. 5in the flashlight fits perfectly in any pocket and comes with a high quality holster for visible carry and convenience. The Fenix user interface for the light is the biggest thing that I personally like. Switching from a dim 10 lumens to 110 to 400 to 960 and 960 strobe is easily done. Charging the light with a micro usb instead of switching batteries is also a big plus. I use this for everyday carry and I couldn’t be happier. Oh and yes it will completely disorient someone (night or day) if not temporarily blind someone. In a city like NYC, where everything to defend yourself is illegal, this light helps to provide some protection while abiding by state/city laws.
