Brynnl S11 LED Keychain Flashlight, USB Rechargeable Portable Mini Flashlight Keychain, 400 Lumens Multi Function IP65 Waterproof Powerful Flashlight for Outdoor, Camping, Hiking and Emergencies

And my confidence paid off! I LOVE this light. The fact that it's usbc and I can just charge it anywhere and specifically before bed on a day I know I used it a lot to get it right back to 100% is awesome. The documentation is OVERKILL on detail, I mean, it has COLOR illustrations and is a double sided folded leaflet! Speaking of charge levels and getting them back up to 100%, it will glow red while charging, and will glow green when it is 100% full. That circuit and it's G+R Leds btw, is a separate bms ic, if you are a geek like me you'll love that it's designed this way, if not, then it still holds value with you because that is just more proof that this was designed with the intent of lasting a as long as possible. Only solid state batteries and a massive heatsink could make this last forever and currently, at this size, both technologies have not caught up yet. HOWEVER, to add to my description of it's high quality design and build, the PCB is THICK, the battery doesn't seem to have any swelling, it truly is AA battery sized but a touch smaller in fact as the sides are tapered to two flat and parallel sides which is great because that shape stops it from rolling off of smooth surfaces. Every triple press function IS super bright so no gentle amber reading light here, but I can't complain when I just use the lowest brightness double press setting for those situations. I would rather conserve illumination time that way. Speaking of which, I can confirm both with my eyes and a high speed camera test at 480 fps, this light does not use PWM to control it's brightness, and if it does, it's at a SUPER high frequency possibly into the 10s of KHZ or higher. The beam spread is super gentle but certainly has a cone shaped throw, this is the ULTIMATE beam shape I could ever ask for. I certain and confident center brightness but a complete gradient from there outward...I'm having trouble describing this...Oh! Imagine a black first layer in a painting program, now use the paintspray tool and give a quick tap of white onto the second layer. That gradient shape is how this light looks in action. The value on sale at sub 20$ is highly worth it, but spending more than 15$ does initially feel...meh...but after using it, and I'm sure it will last, I can see myself spending the 20$ if it never goes on sale again, and being absolutely confident that my hard earned money will go towards a well refined product. One more thing, this will alert you to a low battery level of 15% with an indicator light when you first turn it on. That way, you'll know when you'll need to hasten whatever work you need to use this in the dark, OR, buy two so that you can have one charging and one in use. OH ONE MORE THING! It has pass through charging so your battery life is unlimited if you have a usb power source, HOWEVER, remember I mentioned the use of a heatsink, I personally would recommend against using the highest brightness modes(the two upper ones) for too long as the body gets quite warm while the brightest lights(side lights) and brightest light modes(front light) are used. So, if you use the brightest modes with moderation, just to "WHAT WAS THAT?!", and the medium modes for longer durations to get a project done in dim/dark conditions, I can see this lasting 4-7 years(hopefully longer). ONE MORE THING, Mine said white but when I recieved it, it IS white, but glows green as there are glow in the dark pigment particles scattered throughout the plastic. Nice surprise for me as I like gitd stuff! Happy illuminations guys and gals!

This little thing will take care of most of your flashlight needs. Super bright-charges quick-lots of functions-magnetic and so much more. I just ordered another one to give as a gift.

Just received my Brynnl S11 keychain light and absolutely love it. It has an incredible driver and multiple light functions...more then I realized when I purchased it. I was so impressed I just ordered a second one and am considering buying one more. I have a much more expensive keychain light, but plan to replace with this or let the two of them rotate....equal time on my key ring.This is a quality build and super bright Samsung 6500K 400 lumen LED with 5 levels and great runtimes. In addition it has 4 side light LED's which can be changed from White, White Strobe, UV, Red, Red Strobe and Red & Blue. All this pack in a very small footprint perfect for your keychain. It charges quickly and comes with a short USB C cable.
