Streamlight MicroStream Ultra-compact Aluminum body with AAA alkaline battery, 3.5 Inch - 1.04 oz - 45 Lumens - 66318, Black

This little light exceeds expectations. I have never taken the time to write a review before, but am doing so now because the reviews that others have written helped me to find this excellent little piece of gear and I am grateful for that. There are many other small LED flashlights cheaper than this one but none that come close in performance. It produces a far brighter light than any other using the same battery power. It doesnt have a lot of fancy features that make it harder to use and that I dont want or need (or that break and render the light useless). It just switches on and off. Its so small you can tuck it into a shirt pocket and forget about it - until suddenly you need it unexpectedly and its there, bright and strong. It doesnt dim until you can no longer use it before the battery wears down completely. It does of course dim somewhat, but its still bright enough to use until the moment the battery goes dead. Its rugged too. I inadvertently ran it through the laundry last week. It soaked overnight with the load, then ran through the wash cycle in the morning. I discovered it only when I heard it clattering in the dryer after fifteen minutes. When I took it out, it still worked perfectly, and the case appears completely undamaged. When you figure in the cost savings in batteries and the extraordinary durability of this little rig, it is actually the most economical small light around by far. I have owned it for about a year. I also recently picked up the 66118 (2 x AAA) version of this light. It is marginally brighter and lasts about 2.5 longer before battery changes. I like that one too, but you cannot beat the little 66318 (single AAA) for sheer size and convenience. Im getting a second one now in case the manufacturer switches to a less good factory in the future. I have often seen a pattern in goods manufactured in China: that they are very good at the outset and then the quality declines later. While I have not seen this happen with any Streamlight product to date, Im not going to wait for it to happen.

Have used this light for years! Also, as an aircraft mechanic, sold many of these lights to felllow mechanics. Easy to keep in your pocket, you just have to keep up with it, its invaluable to a mechanic in his or hers line of work. So handy day to day, can;t imagine being without one. Very reliable!

I keep this light in my tech pouch with chargers, cables, and external hard drives. The light seems to be of good quality, no complaints so far.

Got this flashlight for my wife for her work vest and she loves it, says it helps at night when she doesn’t have a free hand but needs a night.

My daily carry. Had one for over 15 years but lost it and needed to replace it. Very brightfor single AAA battery and it lasts a long time. 8 know there are brighter rechargeable versions but I prefer this one because batteries are easily available and many times I dont have to plug it in to recharge. I can just replace the battery and have a working light again. Best bang for the buck.

Using it to replace a Monarch 400 with my Leatherman Wave. It is smaller, and the button is a little hard to push. But if fits in my Leatherman pouch very well, and I love Streamlight flashlights! I’ve used them in firefighting and I know they are great quality. I expect this to hold up well.

I have purchased over a dozen of these for myself and my friends. The perfect gift. My friend, who is a sound engineer for a large theater, recommend it to me a decade ago. As he told me, when you are a 100 feet up in the air trouble shooting lights and you only have two hands, you have to have this little flash light. It is extremely light and very powerful. You can put it in your mouth and you can get your job done safely and efficiently. I have found this to be very true. Ive never had one problem with it ever. It even comes with a triple A battery. It is also a military grade flashlight. There are cheaper flashlights but if you want quality and no headaches, you will never regret this little guy.

The Streamlight MicroStream is a great little flashlight for the price. I bought one to replace my old incandescent Maglite Solitaire keychain light. The MicroStream is miles beyond that thing. There are many things that I like about the MicroStream, and several that I dont like. First of all, while it is not as compact as a Solitaire, it fits easily in (mens) jeans pockets. According to Streamlight, it puts out about 28 lumens, which is plenty bright for use indoors, such as looking for things under or behind furniture, or navigating your house at night or when the power is out. Its usefulness outside is limited. The MicroStream does not have adjustable focus like Maglites do, so the spot of light it puts out dissipates with distance, especially outside at night. Update: Like other reviewers I have started to encounter the flickering problem. Sometimes when I turn on the light it doesnt even light up at all. Turning it off and then back on, or smacking it against my hand, usually causes it to light up, at which point it flickers until it finally reaches full brightness. There is also a small piece that is loose inside the head of the light; I can hear it rattling around when I shake the light. It sounds like it is a very small piece, so I have no idea what it is or how important it was. I still recommend this light despite these flaws. Update II: I bought a second MicroStream to replace my first one. I purchased this second light in October 2015, and it is still working fine in September 2017 (almost 2 years) with no flickering yet. I also stopped carrying it in the same pocket as my keys to protect the lens from getting scratched.
