Streamlight 66318 MicroStream 45-Lumen Everyday Carry Pocket Flashlight with AAA Alkaline Battery, Black

The Streamlight MicroStream is a fantastic EDC flashlight! At 45 lumens, it’s bright yet efficient, powered by a single AAA battery. The compact size fits perfectly in pockets, and the durable black finish holds up well. Reliable, lightweight, and easy to use—great for everyday tasks. Highly recommended for its quality and affordability!

I've used a lot of small flashlights over the years, but the Streamlight MicroStream really impressed me. Despite its compact size, it puts out a surprisingly bright 45 lumens, which is more than enough for most tasks. Whether I’m out on a night hike, working under the hood, or just looking for something in the garage, this little light does the trick.The clip is sturdy and versatile—I’ve attached it to my pocket, hat brim, and even my tool bag. The push-button tail switch is responsive, and I appreciate the momentary or constant-on feature. The aluminum housing makes it tough enough to handle drops and rough use without any issues.Battery life is decent for its size, and I like that it runs on a single AAA battery. Simple, effective, and rugged—exactly what I want in a pocket flashlight. Highly recommend it for anyone looking for a reliable everyday carry light.

This is the greatest pocket flashlight ever made. I have destroyed 3 of these lights over the past 5ish years of carrying them every day and am incredibly impressed by how robust they are. This is really a difficult thing to destroy, and every one has partially still worked despite my abuse.Reverse clip is perfect for use on a hat, which I always use in place of a headlamp which I find bulky and restrictive, there are no modes to deal with, just a pleasant, useful light level that isn't too bright for up close work in tight aircraft service compartments where I often find this level of light most useful.One AAA battery, easy to carry extras, and a good few hours of output per battery.I own a stinger 2020 and this light, and between work and home I never find myself asking for anything else. These lights really aren't that fancy or crazy like many of the Chinese brands with high output and hella modes, but damnit they just work

This is a truly outstanding light, and at $16.00, it competes with other lights in the $30 - 60 range in terms of build quality, form factor, and beam quality. I'm very impressed.First, this is the UPDATED version of the original MicroStream, so if you've read older, pre-2011 reviews (many are still circulating online), you may be surprised to learn that this version has resolved several known issues with the older model. The beam is brighter (28 lumens instead of 20), battery run time is longer (2.5 hours instead of 1.75 hours), the tail switch is much stiffer (nearly impossible to turn on by accident in your pocket), and, though I have no way to confirm it, the anodized coating seems to be more scratch resistant.Second, this light is very small. It is barely larger in diameter than an AAA battery, and the length is about the same as the width of my medium-sized hand (i.e., if you clutch it in your fist, you should be able to palm the entire light). The two-way pocket clip is reasonably stiff and very functional. It can be clipped onto your pocket for a more secure ride or onto the brim of a hat (or backpack strap, etc.) to hold the light for hands-free illumination. I've also clipped it onto the edge of a stroller as a very effective headlight to illuminate the pathway when pushing a stroller at night. The weight is so light you will absolutely forget that you're carrying it. It's only negligibly heavier than the weight of the AAA battery itself. Basically, if you have room for a tube of chapstick in your pocket, you have room for this light.Third, the beam is very clean. It creates a nice, round, evenly illuminated circle of light with no hot spots or shadows anywhere in the center of the beam. The beam has a very effective reach (throw range) of about 15 feet. When you shine it at your feet, it casts a brightly lit circle about 18" in diameter. There is some spill at the edges of the beam, but not enough to illuminate the surrounding area, so it's closer to a spotlight than a floodlight (as any light of this size should be). It's ideal for illuminating a pathway at night, reading in the dark (though perhaps too bright for extended reading), locating a keyhole in a door, or momentarily blinding a potential attacker to gain an edge in a self defense situation.Fourth, the light is certainly weatherproof and, theoretically, waterproof. I haven't tested the latter claim, but there is an O-ring seal on the barrel threads where the light screws together so I suspect it would certainly survive a drop into a puddle or other casual contact with water. I wouldn't deliberately take it diving, of course, but it's not a dive light so it hardly matters.In short, I'm very impressed with this excellent, lightweight, perfect-for-casual-lighting-needs light. I'll probably buy several more and stow them in various places (kitchen cupboard, boat hatch, glovebox, office drawer, etc.) because they're so affordable and useful, yet take up almost no room.

I love this Streamlight MicroStream flashlight! It's super bright for its size and perfect for carrying around every day. The AAA battery is convenient, and the compact design fits easily in my pocket. Highly recommend for anyone needing a reliable light source on the go.
