Review on ThruNite TH20 520 Lumen CREE XP-L LED Headlamp Flashlight -Lightweight Waterproof IPX-8 EDC Headlamp For Indoor & Outdoor Hiking,Camping, Cycling - CW by Kendriece Figueroa

I say superior to the Fenix because while they're similar in price, function and their greatest asset: taking a single AA, the Thrunite TH20 has some niceties I would never want to give up:-Instead of three set levels, there's a varying light output to get exactly what you want.-A super low mode with a 14 day battery life, like 0.7 lumens. I was shocked that this was enough to actually walk around in the dark with it. Not ideal, but I could, and it's nice to know that super thrifty option is there.EDIT: How bright is this ultra low 0.7 lumen mode? If you have a smartphone, chances are you've used the lit screen as an impromptu flashlight to see your way in the dark for a moment. (the screen, not the camera's flash option light) Now open up a blank white bright screen in i.e. "notepad", to get its optimal brightness. See that? The Thrunite's 0.7 lumen mode is about 50% brighter than that, so like I said, very handy. You can definitely read/walk with it and still be very discrete.-Ability to go into flame thrower mode at 520 lumens with a double tap and a 14500 battery. I don't need to go that route, but even the high mode of 250 lumens on a regular AA trounces the Fenix.-The TH20 LED is more advanced, higher performing and more efficient.-There's a "neutral white" option that's tinted slightly yellow as opposed to the cool white option, giving the warmth of an old incandescent. Still very bright, and more like sunlight.-A rubber (non-brittle in the cold) mount. AND, they give you a second one. Fantastic.Watching or reading how the one button control goes through the various options may sound or look a little complex, but after a minute fooling around with the thing I was thinking, "man, this is actually simple!"So, if you're even a casual headlamp user and have one of those ten dollar 3xAAA things, dropping about thirty for this high quality keeper might even be justified. Feeding three oddball batteries into those things was a PITA and I got tired of robbing them from my remotes lol. One AA needed here and a world of options from the performance might have you using it a lot more often as well.In know it's thirty bucks, but "buy-once, cry-once" applies here. This is a great headlamp.
