I haven't seen mentioned a detail if the LR60R light, which differentiate it from all other flashlights in the LRxxR lineup. The four 21700 cells in the LR60R aren't connected in parallel, but in series. Therefore this flashlight, unlike its cousins, isn't powered with a 4.2 Volt power source, but with a 16.8 Volt battery. Normally, powering an LED from an higher voltage source require a buck converter which is much more efficient than a boost converter used when the power source is only 4.2 Volt. The buck converter, coupled with a synchronous rectifier, generated very little heat, and has much longer design lifetime, because the components are less stressed. The reason why a buck converter isn't used in all multi-cell flashlights, is because a battery where cells are connected in series require a balanced charger and a microcontroller to keep all cells at the same level and give an alarm when this is no longer possible. Moreover, the four cell in series must originally be selected to have the same capacity, the same self-discharge rate, and the same internal resistance. Using non-paired cells can cause an explosion, so that is a liability which is expensive to counterbalance. My opinion is, Fenix as used a series battery because of the floodlight LEDs which are placed on the outer ring. Each group is made of LEDs in series, and then the various groups are connected in parallel. In the end, the LR60R battery has five connections instead of the usual two, because of balancing and temperature sensing. The battery can't be replaced by single 21700, and is expensive beyond reason at $200 a pop. In the end, if money is no objection, the LR60R is the most efficient and better operated of the entire Fenix lineup, and therefore used mostly by professionals rather than flashlight enthusiasts. That why I chose it among all LRxxR lights. Hope this helps. Thank you for the great review, and Regards. Anthony
That is a nice Flashlight. I Got Flashlights That are bigger and much more brighter which are The Imalent Sr32 and it's has I20.000 Lumens and The Imalent Ms32 has 200.000 Lumens and one of my Flashlights has a beam that goes up to 2080 meters.
I bought it yesterday and I'm satisfied. I bought from Fenix many torches before - always as a gift and I always was jealous :-D This is the first time I bought Fenix torch for myself. Things that are shockingly good: OLED display and its contents, mode selector ring (I love this user interface: non-touch display and physical buttons. It is opposite to all smartphones and car UI, where there are only touch screens and no buttons, ugh), spot and flood modes, screw-threads, included charging cable, light intensity and beam shape. Things that I don't like: light colour (number of Kelvins could be lower), speed of overheating and battery discharging at the highest settings, it is brutal how fast it deteriorates. I didn't measure it, but I think from 100% to 90% it discharged in the span of 60 seconds on the highest output.
Really solid points here, I had a lot of the same thoughts, while it's by no means is a perfect light, it's definitely a powerhouse and solid lighting tool!
Agree. I got rid of my TK72 for the same reason: it's depressing watching the battery percentage go down so fast. But then, that's only to be expected of these super-high output jobs. In my opinion the battery technology isn't there yet. You can light up the sky if you want to, but not for any practical length of time (hear that, Immalent?)
It just seems like Fenix, although they make great lights and I have several, are several years behind. My Acebeam X75 Micro-arc puts out 65K lumens, in a small package. So far, been great.
They're not behind by any means. They make practical, useful, and "real world" flashlights. They don't have 50,000 or 65,000 lumen unrealistic products that are primarily "wow factors" or "hold my beer" campfire lights.
Those settings are mismatched. Should have more, lower settings on the "Flood" side, start "Search" at 1,000, and have at least one more step between 3k and 21k.
I'd be curious to see a comparison vs the Acebeam X75. Output is higher on the Acebeam but I really like the design of this one, and having an LCD battery readout is perfect for a light that acts as a battery pack.
I agree, the Fenix light has many more features that the Acebeam X75, but for just raw output, the X75 leave the Fenix light in the dust. And don't forget the Imalent lights.

Wow yeah, I haven't heard anything regarding that either, thanks for the insight!

Bruh my dude is holding a car headlight in his hand. That Fenix is so dame bright!
What's crazy though is most car headlights hover around only 3,000 lumens, this is like 7 headlights!🤯
yeah no this thing is absolutely wicked
Trying to resist buying this light is exhausting.
That's so real
Last week i bought Nitecore BR25 for my new bike and FenixHM65R-t Nebula, a beautiful headlamp with warm white light...

Really good looking design and powerful light
Proprietary power cell = hard pass.
Does this flashlight have protect mode from turning on accidentally? I saw when you turn 3 times rotation it'll turn off but didn't get it .

Good take on it. Something for me to consider..although I love my Acebeam X75 and Olight X9R.@@Stevens_EDC_Reviews
@@Stevens_EDC_Reviews solid point
what no way so cool
All videos talk about throw distance of say 500 meters ... and all only show examples on trees 20 meters away. How enlightening is that? 😆
This is totally awesome. Its a perfect SAR lgiht.

Good fishing light

@MrClearview1 just overall runtimes and build quality, almost no light on the market can compete with the x75
Im getting one
How long is Turbo sustained and it ramps down to what for how long after?
I need this please
Ask Santa maybe you will get one for Christmas.
@@TopDog8762 santa wants it for him self.
@@AnilSingh-rn3kx 🤣🤣🤣🤣🤣🤣
The spotlight is only 3000 lumen, the 21,000 lumen is the spotlight and the flood light.
“only”
