flashlight

rechargeable via mini usb

Oh god no

Noctigon KR4.

Tail switch ✓ 800+ lumens ✓ USB rechargeable X

~~However you can get 18650s with USB-C ports for charging~~. Or just grab a couple of decent Molicel batteries and an Eastshine 2 bay charger and just swap batteries.

Worried about forgetting to swap batteries? The aux lights can function as a battery indicator. You can also click the button 3 times and it'll blink the battery voltage. So you should always know when to swap batteries.

There is a ton of led choices. You can also get 2 of one and 2 of another if that tickles your fancy. High cri or raw output. Warm or cool color temperature.

It's worth a look in my opinion.

Another recommendation is the Sofirn SC31 pro

I bought a couple of Aplos T02 as an experiment because they were so cheap and id seen them recommended here. I had low expectations based on the price but I have been really impressed with them, they are 1800 lumens and rechargeable with USB C.

I've tried a lot of EDC flashlights, and my daily carry is one of the least expensive. It's a RovyVon Aurora. Doesn't meet your 800+ lumen requirement (only rated for 650), but that's coming out of a light that's 2.3 inches long and weighs 0.8 oz (about the size of a ChapStick lip balm). I've found it to be more than bright enough to clearly see things at 200 feet on a moonless night. It fits perfectly in my Leatherman Wave holster. The A3 version has a magnetic tail, USB-C charging, keyring, IPX6 environmental rating, and a lockout feature to prevent accidental activation. Unless your daily routine involves a lot of flashlight use, this is a light I can recommend that is unobtrusive and won't dent your wallet at $22 on Amazon.

I really like my sofirn sc31t. Got it for $17 on AliExpress. 2000 peak lumens but it has several settings if you want it dimmer. usbc rechargeable with an 18650 battery. Has a tailcap switch. Might be slightly larger than you are wanting.

sofirn sc18 I have is also good at 1800 peak lumens for about $10, with several brightness settings, but it's more likely to turn itself on in drawers if you don't use the lock feature (quadruple click the button). Also usbc rechargeable with an 18650 battery. No tailcap switch. Pretty small, might be what you're wanting.

Looking at their website, the sc32 looks like it might be what you want.

What kind of beam pattern are you looking for? To take this to the extremes, a 10 watt laser that would be good for a lower tier laser cutters is roughly 1,000 lumens. The same is true for 75 watt incandescent lightbulb. In the flashlight world, the cutting laser would be a thrower and an incandescent bulb is a flooder. The two have very different uses.

I live in suburbia and find flooders great for walking around. I also like flooders for wooded trails, as a light source for working on much of anything up close, and as a light for bouncing off something for ambient lighting.

Throwers are useful for highlighting things far away. If you're in an open space and want to see if there's something wandering around far away, a thrower is the way to go.

There are also things like color temperature and CRI to talk about, but most enthusiast lights offer multiple options these days.

Hey, bit late to the party but I got my other half a Wuben C3 flashlight just for around the house. It was really cheap on Amazon but it certainly gets the job done. I have my rovyvons and lumintops and acebeams and BLFs and Emisars - shout out of appreciation to Hank and Toykeeper and Parametrek for community service - but for an easy, reliable flashlight on a budget, IP68, decent emitter colour (at this price - it’s not blue), listed at 1200lm, Tail switch, 6 modes. USB charging (usb-c from memory) - I’d recommend this for anyone that’s not wanting to geek out hard as a purist.
