ALONEFIRE S11F Fluorescent Small Powerful Mini LED Keychain Flashlight Tactical Portable Bright Pen Torch SST20 LED USB Rechargeable IP65 Waterproof for Emergency with Built-in 300mAh Battery (White)

This is such an amazing little flashlight that I've bought probably 25, or more. They make good gifts. It has a nice range of brightness from just bright enough to navigate in the dark, to blindingly bright. Among the impressive points are the flourescent case of the light which glows all night long making it easy to find in the dark. It also charges quickly. It's so small it can be placed in a watch pocket, or shirt pocket easily. It's just a really convenient flashlight to carry anywhere. The one thing that defies logic to me is that the different models of this flashlight were apparently manufactured in limited runs. I exhausted the stock of their blue flashlights, and have been buying the clear cased ones. If you read this before they're gone, grab one while you can. It won't bankrupt you, and most likely you'll love it.

The lights on this little gadget are VERY bright! I like that there are 4 brightness settings for the white light. There are also red and blue lights that you can choose. The number of times you click the switch determines which color lights up. I found the "police light" beacon really helpful for signaling to people where, on the curb, I am standing when getting picked up at the airport :-) I am small, so can be tough to find me in a crowd, but this light helped a lot. It is small enough to fit almost anywhere (pocket, small purse, I suspect you can even tuck it into the top of your sock if you really have nowhere else to put it!). The light would be powerful enough to illuminate your way in a dark parking lot. I don't know about the battery life, as I have not yet used it enough to exhaust it and at this point, can't speak to the durability either as I have only had it for a few weeks. Also haven't tested if it is waterproof, but that is not what I bought it for. One downside is that the key ring is super tough to slide onto the flashlight - you'll need a tool of some kind (or a long, tough fingernail, which I don't have!) to help pry it open. Other than that, I'm happy with this purchase.

[+] I have used it sporadically for an estimated 3-5 hrs continuous use on high power or strobe without any noticable dimming in brightest mode[+] The lumens listed in the product description are accurate based on what I can tell because it is surprising bright[+/-] The mode features are awesome and I used the siren mode to prank a friend and he believed it was really a police car. HOWEVER, The magnet on the backside works, but I definitely wouldn't recommend putting it on the outside of a moving car more than a like 10mph[est?].[+/-] The button combinations to press for various modes can be a big cantankerous and hard to remember (at least for me) but they all work as listed[-] No specific negative aspects come to mind thus far, but I will update my review if I do find any downsides.

GOOD-Rechargeable-Uses USB C for charging, the future seems to point to this type of connector-Small magnets that don't grab stuff, but are strong enough to hold it in place-Low power modes-Comes with keyring, which may work it for your use case-Charges fast-The location of the power button makes it less likely to turn on in your pocket/bag-It has a red flashing mode so you could use it for a back light on bike if you need to. It does not have a convenient way to attach, but it would not be rocket science to dangle it from a bag or bike seatBAD-Sort of complicated operation with 1 button, you can learn it, but...-The 'double click' to get it to stay on is a very fast double click.-Does not come with caribeaner, which is probably what you'll need-Magnets may cause problems in your bag. They are sort of a gimmick, may be useful but not necessaryMEH-Uses non replaceable battery, which means you can't carry a spare, but it does recharge fast-Blue/Red police mode may get you in trouble if you're goofing around with it in public-Expensive? Well, it's probably worth it but if you need a super basic light cheaper alternative exist-Glow in the dark feature, may be useful if you drop it in the grass or something, if you had a lanyard that would not ever happen

Almost a perfect pocket light. Light just needs to include a pocket/hat clip and fix the side beam mode to make it perfect.Pros:Pretty bright for a tiny flashlight.Main beam has memory (flashlight remembers the last beam brightness used)Decent battery life.Charges quickly.USB C to C charging supported.Flashlight can be used while charging.Fluorescent shell.Meh:No high CRI emitter option.Cons:UV light is dim. I have to stick the flashlight right against a bill to see the UV security features.The side beam has a white beam mode and a red beam mode. There's a blue LED, but it only come on in police flash mode. Why isn't there a blue beam mode like the other colors?Side beam should have memory like the main beam.The magnets are WEAK. Sticks OK on horizontal surfaces. Only sticks to vertical surfaces when the magnets are aligned vertically.No hat/pocket clip.

First off, the most important feature regarding charging does work properly. Many "USB type C charging" flashlights can only charge with type C to type A cables due to the lack of an internal resistor on the device.This flashlight does not have that problem.A single press and hold will activate turbo and turn off when you let go. Also, a quick double tap from off will turn on the light to its last remembered brightness state. (There are 4 levels of brightness)It also has a triple press flood light on the body to illuminate things close to you. It even has a red light in the body for preserving night vision if you do astronomy, etc.The color temp is about 6500k from the SST20 emitter. Hopefully there will be a 4000k version with the higher CRI for better color in the future but that comes at the cost of efficiency and brightness. All in all, it's a perfect EDC city flashlight and useful for healthcare workers.The glow in th dark body helps me not lose my keys in dark places.

This is a great little torch!Very compact, lightweight and very bright! USB-C charging port is easily accessible.All the extra LEDs along the body will be handy from time to time I guess.Magnets on base hold it on a vertical metal surface ok.
