    A very well made flashlight. The highest of quality. I use it to walk my German Shepard by the river every night. Lots of critters to see. Levels 3 & 4 are perfect for this while 5 makes a statement. Buttons are very user friendly and functional. Easy access to strobe helps with the large cats. They hate it. Love this light.

    This is an amazing flashlight! If you want bright, this is the one. It is a little heavy, but the battery lasts over 7 hours on Level 3 (this is bright enough for just about any need). Level 4 is about the same as High on my UC35. And Level 5 turns night into day! I love it.

    So far really good. Dropped it in a creek while it was turned on and it came out fine. Battery seems to be good.

    Like this light a bunch; great for sweeping the yard before letting the dogs after dark but I wish it had a bit more of a focused beam. Can get a bit warm real quick on the higher settings.

    Light is just ok. I use the light for everyday carry and here are some of the issues I have ran into. The first problem is the power switches. I use the light in the provided holster and the switches protrude from the housing causing the buttons to get bumped and activate the light. There is a lockout feature on the light but that is such a pain to use and when I need light it is generally on emergency basis. Second problem, charging port cover. The charging port is located on the opposite side as the power switches and the cover gets caught on the side of the holster when inserting the light. I’m sure the charging port cover will get ripped off sooner than later with all of the times the light gets re-holstered. Third problem; standing upright. One of the best ways I have found to light up a room is by directing the beam of a flashlight at the ceiling of a room. This light has two notches on the back for a lanyard to attach to and they do not allow the light to stand upright very easily. The light needs to be on a very smooth and flat surface for it to stand upright. My suggestion to Fenix would be to recess the switches and the charging port cover and shave the tabs off the back.

    Other than the three problems noted above I love the light and will continue to use it for EDC. The screen for the battery readout, high lumen output, and size are great features and the main reasons for purchase.

    I received my torch today, and it is awesome – very bright. The 2nd light I’ve bought by Fenix. Very satisfied, and looking forward to years of reliable service from this light. Great size.

    Absolutely love this flashlight. Purchased it for my home inspections. I love that there’s 4 modes, highest being over 3000 lumens. I needed a rechargeable flashlight and this fits the bill. Wasn’t initially seeking out this feature, but love the LCD display that shows battery life. Highly recommend

    I purchased this flashlight for my home inspections. Needed a flashlight with high output (greater than 2000 lumens) but also be able to scale down to 1000 lumens when needed. And it had to be rechargeable. This flashlight fits the bill and then some. I love that fact that it’s small enough to fit in my pocket when not in use. Hopefully this light will last me a while. Absolutely love it so far.

    The two features that made me get this flashlight are the high lumen output and self contained rechargeable batteries. The adjustable brightness is great and I like that the beam is more a flood than spot as I plan on using it away from urban areas. Using a 5V/2A converter gets the battery fully charged in a reasonable amount of time.

    This light is amazing! No more not knowing when the light is about to die, this thing puts out a massive amount of light, and lets you know how much battery you have left the whole time. And that battery will run forever. I bought it as an EDC, but it was a bit bulkier than what I liked, so I ended up also getting a UC30. Couldn’t bring myself to get rid of this one though, I use it more than all my other lights. Great job Fenix!

    Over the years I have purchased nine (9) Fenix Lights. I got my first, an LD20, as a gift about ten years ago. From the AA battery operated LD20 to the 4000 Lumen TK75, and seven other various sizes. I collect them. This UC52 looks like a beauty. I like it’s simplicity in operation. One click, you’re on SOS Mode, one click to the Strobe Mode. A very helpful characteristic is the little LED that shows how much time one has left on each level of brightness. i.e. 80 hrs@Level 1; 27 hrs@Level 2 ; 8 hrs.@Level 3; 3:40 hrs@Level 4; and about 1 hr. @Level 5, Turbo. ( My readings at full charge )

    I discharged the UC52 fully and charged it through the USB connector. It took about 3 hrs. This light has to have a voltage step-up transformer for charging. It has a 7.2v built in battery, but the output voltage at your USB port is only 5.0v, and we know that any d.c. battery had to be charged above the potential of the battery.

    To conclude, I feel this will be one of my favorite Fenix Lights. It takes the guesswork out of knowing how much time I have left at each intensity level. Fenix does it again in their improvement and utilities of their products.

    I just received my UC52 yesterday and it is going to live in my car. The strobe will be a good first line of defense when I go somewhere that I cannot carry anything else. I am disappointed that a light in this price range does not have direct access to Eco and Turbo and there is no way to know what level it will start at when you press the power button. Since turbo is so bright it could be a bit of a problem in a dark room if you are not expecting it. I will have to try to remember to switch to Eco before turning it off which is a bit of a pain. Something like a longer press for direct access to Eco and maybe a double click for direct access to Turbo would make this a great light
