RovyVonG4 Aurora A8 USB-C LED Keychain Flashlight, Momentary On, Lock Mode, Max 650 High Lumen Super Bright with EDC Mini Size, USB-C Rechargeable,8 Modes,Gift for Checking,Reading(365nm/White)

Awesome flashlight. I wish I had it in 2017 for HARVEY, and 2021 for THE BIG FREEZE here in Houston.It took a few minutes to figure out the single button for the four levels of light. Here is a small tutorial (all levels start from the flashlight OFF):1. First Level. (front light) Press and HOLD the button for a single," light up a dark room" light. I love that this is first if I need a light in an emergency. Press and Hold the button to turn off the light.Once you reach a level, a simple single press of the button changes the lights within the level.2. Second Level. (front light) Pressing the button twice (very quickly) brings you to the second level-- four different white light levels in the following order: A. Medium Bright. B. Bright. C. Extremely Bright D. Low Light. Press and hold the button to turn off the light.3. Third Level. (side lights--I turn the flashlight over so the button is on the bottom when using this level as the side red lights are VERY BRIGHT and I want them pointing toward the ground, not up in my eyes) Pressing the button three times (very quickly) brings you to the third level--one blue light and three red lights (see manufacturer's description for their uses). A Blue Light. B. Steady Red Light. C. Slow Flashing Red Light. D. Quick Flashing Red Light. Press and hold the button to turn off the light.4.Fourth Level. (side light) Pressing the button 4 times (very quickly) brings you to the fourth level--reading lights. A. softer light. B. brighter light.This is a very powerful light in a tiny, lightweight case. Easy to use, easy to charge, easy to carry. An engineering marvel. Highly recommend!

it is very small. Maybe just a bit large for a key chain, but still pretty small. VERY bright for its size. Would like to longer run time, but that of course means it would have to be larger. Since it is rechargeale via USB, i can easily connect it to my power pack and top it off. For me a great compromise. I especially like the built in UV light and the flasher. you can use it for conspicuity on the bicycle or walking down the street at night. Really, a wonderful feature set for the price. Special mention for the clip. It is easily changeable so you can clip it on your cap to watch what you are doing. Also, really good choice on brighness from very low (good for lighting the tent at night) to really hurt-your-eyes bright.I would like to see a removeable cover to keep on the lens so it does not get scratched. Also would like to see a replaceable battery (not sure if it has one or not!) I use it for EDC and have not seen anything better/more versatile.

I got this for work looking into machines with dead lights, and wanted a UV light option to test certain materials. I figured it would be worth it even if it wasn't great compared to what other brands charge. Turned out to be much nicer than I expected, quite bright and with good battery life given frequent intermittent use (though it lasted through some plumbing marathon sessions too). Not 100% on the UV frequency but will definitely get anything generally florescent or glow in the dark shining brightly. If I ever need to replace it I'll definitely buy one again, and I've recommended it to friends. If that doesn't sell you on it IDK what will.

This light meets most of my criteria that I was searching for in an EDC light. I work with cash a bit and the UV is plenty strong for verifying US bills. The red light is plenty bright and the flashers seem like they will be great for walking or biking at night. The lights out of the front are plenty bright and the 4 steps are fairly well spaced as far as brightness goes. Battery life has been good so far.If I had the chance to make any alterations to this light it would be to integrate a magnet into the tail, enlarge the on off button slightly for folks with larger hands, and make the clip a bit more stable. I do like the clip and the fact that it is reversible but it doesn't take much to pop it off. While that is great when you want to alter it's placement, it kind of sucks that you can't easily clip it into a pocket without the clip falling off.Other than those things though it's an excellent light for EDC when you want something powerful, lightweight, and rechargeable.
