NEXTORCH K40 Keychain Flashlight, 700 Lumen Pocket EDC Rechargeable Flashlight with UV Black Light, Red/Blue Light, 3 Modes and Strobe for Everyday Use, Dog Walking, Emergency Defense, Beacon Location

Awesome little keychain light

This is an impressive little light for its size, and is relatively simple to use. I do have some notes on the controls, but there's nothing showstopping here. The three brightness levels of the main lamp are useful, starting at very intense and dimming to a level that won't ruin your night vision. There's no PWM flicker on the lower settings, either.First, I have to salute Nextorch for correctly implementing USB-C charging. It has the proper pulldown resistors to request power from a USB-C charger, even with an e-marked cable. I ran the light until the battery was empty, when the light shut itself off. It took an hour and fifteen minutes to filly recharge, and took in enough energy to be within the battery's 180mAh rating. That's pretty small, but it's also a tiny keychain flashlight.CRI is surprisingly high for the main lamp. It's still cold white, but color is noticeably better than other pocket flashlights I have. The UV LED is 365nm, further into the ultraviolet end of the spectrum than your traditional 395mm "blacklight."Pressing the forward button, which is labeled with a starburst and doesn't immediately look like a button, controls the main light in steady mode. It starts at high, medium, then low before shutting off. If you wait five seconds between presses, the next click immediately shuts it off. Long press does nothing. I'd like the first setting be low, but this is down to personal preference. It can only maintain the high setting for a minute, before dimming slightly. In this state, it's still brighter than the medium setting. It's disappointing this minute limitation isn't disclosed anywhere, but also expected as it's very common on these small flashlights.The more prominent of the two buttons, towards the rear, is the secondary. A short press instantly puts it into an annoying strobe mode. Long press is for UV, red, and blue LEDs. Personally, I'd like that reversed so seizure mode requires a long press to activate. A long press is also required to turn the UV/red/blue lights off, instead of short like the main beam. Annoyingly, you also can't use the blue LED on its own, instead only in the flashing 'police light' mode.A small LED sits between the buttons, and turns on momentarily when the flashlight is activated to display battery state of charge.Build quality is very high. While the body of the light is plastic, it seems to be very tough polycarbonate, the same thing safety glasses are made from. I do have some concern about the lanyard/keychain loop breaking off, but it's probably strong enough. I also imagine the shiny outside will get scratched up pretty quickly; a matte finish may have been a better choice.This flashlight overall meets its claims. While I do find some of the 'software' decisions with controls less than ideal, nothing is even remotely dealbreaking. The only real oddity is the blue LED only being useable as part of the 'police light' flashing mode. Otherwise, it's build well and the CRI is surprisingly good. I do think the twenty-five dollar price tag is a little high for what you're getting but I don't find it egregious. You can find small flashlights with larger batteries and similar light modes and brightness for a lot cheaper, but this one definitely has an edge in CR and build quality. Generally, I do recommend it. Some control tweaks would make it perfect!

This is a cool little light that has great output and is perfect for a keychain.

This is a great little gadget that is totally worth taking up a keychain space in my bag :) It has a lot to offer for it's compact size. Plus, the size itself makes it wasy to travel with and also to conceal if carrying as a self-defense strobe light.There are various lighting options, all outlined in the included instruction booklet. Comes with flashlight, charging cord, and clip (one to attach to back and a pen-type clip on the side of flashlight). The UV light is a neat feature yo don't see offered on many flashlights, as well as the emergency blue/red flash. The write strobe is also very effective. I feel like it would actually be able to to deter or ward off an attacker with the strength of the white light blinding them. You can't carry many self defence items when traveling due to safety/TSA restrictions, so this is a nice option for travel.Tested and verified waterproof function is legit (ran it under water and pushed the buttons to rotate through diff lighting functions). The body/case of the light is all clear. It's form and function -- because of the crystal clear body, you can see all the working parts inside (which looks cool lol) and also allows you to maximize the tiny real estate it has by utilizing the various sides and surfaces of the small flashlight to mount its lighting features.The buttons are a little hard to press, but I think it might be because they are on the smaller side (understandable as the overall unit itself is pretty tiny) and might also be due to the waterproofing aspect...so that you can press the buttons while wet without letting water into the unit. There are only 2 buttons to operate -- one for the refular light, and the other for all the fancy modes. There are some press and hold instructions, as well as toggle functions, but nothing more complicated than you'd find on other flashlights with multiple lighting options.The multi-clip function is nice. The keychain is straight forward, has a ring and caribiner. The ring on the butt end of the flashlight it made of the same thich plastic as the body, so it feels sturdy, but also concerned it might crack off is handled roughly. Will update if that becomes an issue, but seems sturdy enough to hold up with normal wear and tear.Mostly use the keychain style but the other side clip allows me to clip it to my shirt/pant pocket or to my hat/visor to use as a pseudo-headlamp. The clip is a little tight, but makes me feel like at least it won't pop off. It feels like it might break when you're stretching it, but it will be ok. Could see it possible putting a small indent on the bill of your hat if left for long period though. Will probably put it on a tether/retractable type of keychain so that I can hang it on my purse but be able to easily access it when needed.The flashlight utilizes a USB-C port to charge. I have a mixed feeling about rechargeable lights...alkaline batteries make me feel more comfortable for emergency type instruments so that you can use it on the spot and not need to worry about the elctricity or time you need to charge something. However, for this particular item, the rechargeable feature is nice because it's a quick charge and seems to last quite a while per charge (with occassional use...would vary with heavy use). For the price and quality, I would recommend to friends and family as this is something I will be adding to my everyday carry :)

This flashlight is about the size of a double A battery and yet it provides a wide beam of light that rivals some pretty big 700 lumen flashlights. The build quality is great, although it has quite a bit of plastic. It is small enough and light weight enough to go anywhere with you, and the fact that it is rechargeable means you won't need the additional burden of replacement batteries. 2 button functionality means this light is easy to use and figure out. This miniature flashlight comes with a pen clip in case you need to clip it on a shirt or pants pocket, and it also has a keyring hole for hanging it on your keys or carabiner belt clips. I am fully satisfied with this product and actually very amazed by the light output from such a small and efficient LED light.

I was hoping to get this for the UV/blacklight functionality, but unfortunately that part of the flashlight is a little disappointing. It’s just a tiny led on the top of the flashlight, not the main part. I wanted to use it to check for invisible mold in my cabinets. That said, despite this odd reason for ordering the flashlight, I can’t really dock any stars because the flashlight itself is great. It’s small, fits nicely on my keychain - and yet quite mighty. Good for night time walks or needing to see things in the dark. The battery life seems fantastic. My 5 year old daughter plays with it endlessly and it’s still going strong. Overall, good value for the price.
