I have quite a few Fenix lights from over the years. Every time I buy a different brand, I’m disappointed. Every time I buy a Fenix, my expectations are exceeded. I even purchased a Surefire a few years ago and wasn’t thrilled with its performance.Prior to this purchase, my favorite Fenix lights have been:PD25 – A very small and compact light. Much brighter than it seems possible. I think it’s 640 lumens? A great carry light. Only a few inches long.PD40R – This has been my long-time favorite. On max it’s 3000 lumens. SUPER bright! This was my first usb rechargeable Fenix.I received my LR35R 10,000 lumen light last week. The build quality is fantastic! It’s not much longer than my PD40R but it is heavier and thicker.The batteries fit inside the handle and the way they mold the handle makes it fit great in my hands.At first, I thought I might be bothered not to have the on/off switch on the back like other Fenix lights (my PD40R has a rotating bezel to turn on/off). But the button is conveniently located right at thumb level when holding it in my hand.A quick press of about ½ second turns it on and off and when turning it on, goes to the last used setting. If you hold it for more than ½ second when either on or off, it goes into blinding strobe mode.It comes with a great sheath that can be worn on a belt or attached to a mole panel. I put it on a mole panel in the back of my truck seat.When putting it in the sheath, I engage the lock function. If you QUICKLY double press the on/off button it locks the light so it can’t accidentally turn on. It has to be a quick double press though. Once locked if you try and turn the light on, it flashes twice in low (eco) mode to show it’s locked. A quick double press again unlocks it and puts it in eco mode.If you quick single press the button when the light is off, it shows you the battery level. I think solid green is full, blinking green is reduced, then maybe solid or blinking red? I haven’t got to that point yet.It also comes with a clip on the light. Great for clipping it in my pocket.There are 5 brightness settings.The lowest setting (Eco) is only I believe 50 lumens. At first I thought this was pointless. But then I used it to read some small text at night. It was perfect for that. At this low setting, there is no glare when reading text on white paper.The second setting (low) 450 lumens is perfect for outside dog duty at night without blinding lights on dogs or freaking out neighbors.The third setting (medium) at 1200 lumens is a normal powerful flashlight brightness. Pretty useful for most tasks.The forth setting (high) at 3000 lumens is freak’n bright. It is as bright at my PD40R (also at 3000 lumens) but the LR35R has a wider pattern. The PD40R bright pattern really has great distance. This LR35R has that great distance but at an even wider pattern.The turbo setting (high) at 10,000 lumens is un-believably bright. It is insane! And a very wide pattern. I have other flashlights that advertise 10,000 lumens. But so far, none of those come even close to 3000 lumens, much less 10,000. I would say, 10,000 lumens is pretty accurate for the LR35R on ‘turbo’. The only use I can think of for 10,000 lumens are, long distance search, or complete blindness for anyone looking at the light!Some complain the turbo setting produces a lot of heat. And I agree. However, I can’t imagine anyone would use Turbo mode for an extended period of time and touch the front of the light. For me, I will only use this mode sparingly. And use it, just because I can!So, based on build quality, comfort in my hand, and complete usefulness across all of the lumen ranges of this light, this is my new favorite go-to light.
