The Advantages of LED Light
An LED is ideal for lights that are used often and over an extended period of time. You don't have to worry about breaking the light, since there is no glass or filament, and you rarely have to replace LEDs because they can last a lifetime. Save time and money on batteries as well--they will last much longer with an LED than with a regular light bulb.

Innovative Technology Provides Bright, Powerful Illumination
The Nano Light uses a five-millimeter, super-bright, white LED that is impervious to shock and lasts 100,000 hours, so you'll never need to replace a bulb again. A parabolic-shaped LED area optimizes the beam performance and gives increased light output.

Easy Operation and Handy Snap Hook
Simply rotate the head of the Nano Light approximately a quarter turn to switch on the light, and rotate it back to its home position to turn the light off. An easy-to-use, non-rotating snap hook attaches and detaches easily with single-handed operation, allowing you to store the Nano Light on key chains, coat zippers, D-rings, belt loops, and more.

This well-constructed little flashlight is much brighter than I expected. I bought for use inside a tent, for which it is really too bright, but it's perfect on a keychain for lighting a path or door locks. Unlike many other LED keychains, you don't have to continuously press anything to keep it on, just twist the handle 1/4 turn.
The flashlight is really solidly built and extremely lightweight. Whenever they finally give up, I'll be replacing the included LR41 batteries with SR41, which cost about the same and last longer. For what you get this flashlight is a great bargain!

I've needed a small flashlight for quite a while, as our backdoor is not well lit. I thought I would get a small single AAA flashlight, and found a very bright one for just under $50 (Fenix-made). However, after reading the reviews on this one, I decided I couldn't go wrong with trying the Nanolight.
This light may only be a 10+ lumen, single-LED light, but it is brighter than a 9 LED light we bought at a hardware store (for $2) that requires 3 AA batteries. Amazingly, this is so small that it is barely half the length of my thumb and more thin than any point on my pinky finger. It has a nice clip that fastens it to your keychain in a snap.
I bought one for myself and my wife, and we use it in place of any light in our car.
With new LED technologies just around the corner, why pay more for other, expensive LED lights when you can get this for so little and choose to upgrade later if needed?
We will be buying a lot of Nanolights for Christmas later this year. It is water-resistant, powerful, and always there when you need it without taking up room in your pocket.
There are two drawbacks. One is replacing the four tiny alkaline batteries (using the same size hearing aids use). Fortunately, the cells are pretty cheap and the light is supposed to last up to 8 hours on a set. The second drawback is that the light has a real tendency to fall apart the more it is used. However, there is a fix for this. Simply put Teflon tape on the threads.. This will keep it waterproof while assuring the bezel can't easily work itself loose.
Once you get it, you will wonder how you got along without it.
UPDATE: I've found out that the hearing aid batteries that work in this light are zinc-air batteries. They work, but they require access to air, which means when the batteries exhaust the air in the waterproof casing, they stop working. You need to unscrew the top and let it set for a minute or two to get the full charge back.
Please search Amazon for bulk LR41 batteries--you will find them so inexpensive that any concerns about availability or pricing for replacements will fade away. These are alkaline batteries, so you won't have the problem I mention above.

Super-tiny, excellent little flashlight. This makes a ton of light, given its size.
Pros
* Perfect keychain light
* Super-small... you have to see it in context to get how small this is. (Added a photo.)
* Great value (price-for-performance ratio)
* Excellent gift idea
* Durable finish
* O-ring sealed, nicely machined
Cons
* Very minor, but the ridges on the front that let you turn it on and off, aren't very deep and thus turning it isn't as easy as it could be if they had deeper ridges.
Other thoughts
I have used this in a pinch when my larger flashlight wasn't handy or was in use elsewhere. This easily lights up door locks, closets, pantries, a freezer at midnight (hmmm), and just about anything that one would have used a 2-AA penlight for in even the fairly recent past.

This is a very very bright keychain flashlight. I was shocked that is was smaller then I first expected. It is just a little bit bigger than a quarter. View my posted photo at the top. Before this key chain I got the Swiss+Tech bundle package from Costco and it comes with a solar rechargable battery keychain flashlight (K.F.). That keychain flashlight was only half it brightness compared to this Nano Light. Another issue was the battery gets drained really fast on the Swiss+Tech K.F. like within 30 minutes. It also must be always charged from bright indoor light or out in the sun light.

Just like everybody says it gives off a descent light, but remember that it is a key chain light only meant to help illuminate low lit areas like the keyhole of a door. To give you guys an idea it will illuminate a corner of an average sized bedroom. For its size this is as good as it's going to get. If you want something brighter you're going to have to settle for something a little bit bigger, with higher lumen output. The range is not great but sufficient for my purposes.
There isn't a button switch like most flashlights. Instead you have a twist switch, but you can turn it on momentarily. If you push the top of the light down, the light will turn on momentarily. If you twist the top, it will stay on constantly. I don't know if Streamlight designed it this way, but it works for me.
I have no issues operating this with one hand. Some people say it's difficult but I have no problem whatsoever. I have small hands.
It has a clip on the back that lets you easily attach and detach if need be. This is a plus for me.
I have nothing bad to say about this little light except that the batteries for this light is not as easily available as other batteries. Not a big problem for me because I just bought 50 spares online so I have them readily available.
Buy this now, you won't regret it.

Great first impression. It is machined very nicely. Looks really cool in bronze color anodized finish. Much much smaller than my maglite solitaire so I will actually put it on my keychain and it seems brighter too. Smaller in form factor than a chapstick as well. Has a few o rings. No lens over LED and that means you can't scratch the lens.

This is the best keychain flashlight I have ever seen. It is so small I can't even tell that it's on my keys. And it's brighter than my double a maglite! Highly recommended
By AVJGUY
I am guessing this little flashlight is a bright as my (very) old mini mag light ( 2AAA batteries ). I'll probably only use this about ten minutes per week, so if the batteries hold up for several months at a time, I will be very happy. Impressed! In the picture, the Streamlight is sitting six feet from the peg board on the hood of my truck. The shutter was open for 2 seconds, but the picture is fairly honest. No adjustments to brightness or contrast in any way!

Obviously, don't expect this to be a replacement for a much larger flashlight. That said, if you need a small flashlight that you literally will not notice on your key ring that provides a great deal of light for its size, look no further.
This light could easily replace many larger flashlights. The LED is very bright - bright enough to leave residual images in your eyes if you look into it for a second - and so tiny that you will barely notice it on your keys.
I am getting one as a gift for several family members for the holidays.

Received one for my birthday from my instructor, and I've gotta say--I wasn't expecting this tiny little thing to put out this much light. 10 lumens doesn't sound like much, but it appears brighter than my Fenix P1D on its "Low" setting (rated 12 lumens). Mine has a slight violet tinge to the beam, which I like given that I find that it helps me find small details easily missed by normal inspections.
Construction is like that of a MagLight, milled from a solid piece of aluminum. Operation is easy, even one-handed. Feels like it could take a beating without loss of performance.
I'd give it 4.5 out of 5 stars because of the (included) unusual batteries it uses (compared to 123 batteries), but LR41 batteries aren't uncommon. Not really a detractor, though; it most likely replace my P1D for everyday use.
Final word: Great deal. Highly recommend.
