Terrific EDC light!
June 4, 2015
I have several MicroStreams! I think they're one of the best values out there in small EDC lights. They have a very good clean spot with an excellent balance between spot and spill. The color of them is overall very good (although my newest one is biased a bit more towards cool/blue than my other ones). The switch is excellent and very durable; my oldest one has been used hard for several years and still works fine. The finish is holding up very well, too. The two-say clip is excellent and versatile. For carry you would normally use it lens down but the S-shaped clip can be reversed to clip to the brim of a hat or ball cap. The size is perfect. It's one of the smaller AAA lights I've used. There are brighter lights out there but the MicroStream offers a good balance between output and battery life. I run lithiums in mine and usually get a year of EDC use between battery changes. I'd estimate a Lithium cell to provide about three hours of steady light, depending on temp, etc. Lastly I appreciate that Streamlight throws in a lanyard loop and a spare rubber boot for the clicky switch. That's a nice bonus that should keep the light going for several years. This is a great light and a great value. No point in carrying junk when you can have something like this for well under twenty bucks!
* Good output * Water proof * Excellent shock resistance * Superb reflector with very clean beam * Highly functional pocket clip * Very compact * Nice finish * Includes extra rubber boot for clicky
* Could be brighter I suppose * Clip isn't removable

Very durable and reliable flashlight. Bright, but not excessive. Battery life is good and one 1 AAA. Highly recommended!

Great Pocket Light
January 6, 2015
I've owned (and lost) a number of these over the years - good thing the price is so reasonable.. Nothing fancy, won't blind anyone, but plenty of light when you need it the most - and you'll have it because it is small enough to carry everywhere.

Very nice little light! Someone once said "the light that will do you the most good is the one you have with you." This light is very easy to have with you when you need it. I really like the two way clip. You can have it in your pocket or on the bill of your cap for hands free use. Good job Streamlight!
Small, easy to carry, light weight, two way clip.

Carry everywhere
October 17, 2014
I have this in my pocket every day for a couple of years. I have not had trouble with accidental activation carrying this way. Having RP low vision problems, I am always in need of a bright light source. I have used it for dropped items to working on machines to reading menus in dark restaurants. I use rechargeable batteries and they have good life for just one AAA..
Holds up over time and usage.

Did you ever own something that just 'worked'?
October 5, 2014
That's the Microstream. I have owned Microstreams since they first came out. Like all Streamlight lights, it is well built and well designed. It is amazing how much light it can put out for a single AAA flashlight. The relatively deep reflector plays a part there. The beam pattern is nice, with few to no artifacts.I have EDCed this light for almost ten years now (not the same one, they keep running away from home!), and have no plans to switch to a different one.
Well Built Inexpensive, especially for the quality Two-way pocket clip Bright Good run time, especially with lithium primaries
On/off switch is a little stiff. I liked the version 1 switch better, but I guess people had an issue with it being too easy to turn on inadvertently..

Amazing throw for such a tiny light
September 16, 2014
I've had one of these for some time. In terms of lumens, it's no brighter than one might expect, but the reflector design is exceptional, resulting in a nice concentrated beam that will reach out across a room in the dark to check window locks, ceilings, or whatever you need to see. The beam is cleanly transitioned to a bright center, with no dark shadows or irregularities. Like all small, low-powered lights, it excels in totally DARK areas, as any ambient light will compete with it and cause your eyes to adjust, making the flashlight less effective. It will make it seem dimmer to your eyes. A battery lasts a fairly long time considering how much you get in terms of throw distance. It's also a well-built, tough little light. The rubber switch cover is still intact on mine despite between 2 and 3 years of use. It is very small, so it can be carried in a pocket with no hassle at all. The pocket clip works well and mine has held up just fine. Highly recommended. The best AAA light I've used.
Small size Excellent throw Clean beam transition to a bright spot - no shadows or irregularities Good pocket clip Gets a lot of time out of one AAA battery
Does not come with a sheath Brightness limitations inherent with size constraints

Streamlight Microstream LED 66318
September 12, 2014
I work graveyard shift at a hospital and need to check patient's ID bands. The Microstream is perfect. Small enough to carry in pocket and provides more than enough light. Very well made. Tailcap switch easy to push for momentary light, takes a bit more effort to click for constant light. Replaced my Streamlight Stylus Pro which I like very much but my sweetie said it was tearing my pocket. Win, Win: I get to buy another flashlight and it will hopefully keep her happy. Have not had it long enough to comment on battery life, switch longevity, etc. but its a Streamlight. Good enough for me.
Small Well made Streamlight
Switch needs firm push for constant on mode

An amazing little light
June 10, 2011
I have ordered several of these lights over the last month because anyone that sees it wants it and for the price on battery junction you just can\'t beat it. It\'s a perfect light for carry in your pant pocket or shirt pocket. My wife also wanted one for her purse. Overall i rate it a 5. I have not found a deficiency in it if keep in mind it\'s size.

No Brainer
March 1, 2011
This is a perfect every day carry - simple and tough, its rare to find a small light with a rear clicker switch....its only 20 lumens, but that is plenty for most uses....if you have only one light, you could do worse than this little light that fits in your pocket, very light....match it with some rechargable AAAs and you are in business, never ran mine with Lithiums, maybe even brighter?

Tiny, Tough, Bright!
February 11, 2010
Incredible light for its size and weight. The light runs on a single AAA battery but is brighter than my Maglite that uses two AA batteries! Just like the reviewer before me, I accidentally put the light through a wash and dryer cycle... and it still works! I love this light.
