Keychain Flashlight

Absolutely fantastic flashlight. I bought it thinking I would need to use 10440 batteries in it to have enough brightness for how tiny it is, but wow was I wrong! Even a AAA battery puts out a ridiculous amount of light for how tiny it is. I could work on a car with this thing if I had to, it is that bright. All I use this for is everyday carry light duty stuff looking for problems/leaks on analyzers in the lab I work in, and it is excellent. Battery life is also great, but I honestly have not used it enough to give an accurate idea of daily-use battery life because I do not actually use the light every day for a significant amount of time. Look at other reviews for battery life info. I do recommend storing the light in your pocket with the barrel slightly unscrewed because I have had the tail switch get turned on in my pocket once and it killed the battery. Not really a big deal to me though, I just test the light once a day to make sure the battery is still charged and see that it's at full brightness. The silicone glow in the dark diffuser they send with it is also fantastic. Just a second or two of the light being on and the diffuser gets charged enough to be surprisingly bright at night for minutes at a time. I can successfully navigate a pitch black area indoors from just the diffuser glowing. I also carry the light with the diffuser on 24/7 because the light is still bright enough it to use for general flashlight purposes. This gives me the option to have the diffuser on or off whenever I want/need it, and the silicone is high enough quality that it will last a long time if properly looked after. Overall, I love this flashlight and I will be buying a few of them this holiday season to give out as gifts!

Great little flashlight, nice and bright. I keep it on my keychain and always have a flashlight handy which is usually better than using my cell phone as it is more focused and compact. I accidently jumped in the pool with my keys in my pocket and the light still worked fine.

1. The color is a matte finished steel gray with a hint of purple. Unique enough to tell it apart from others, but keeps to the gray scale nicely. 2. The size is very comparable to the K18. I could even use the diffuser with this older model K18. This keeps some parts interchangeable between models of the same caliber. 3. The diffuser is very effective and glows in the dark without the need to be exposed to UV. The same goes for the green halo inside the lense. 4. This chain clip looks to be easily removeable from, but will be difficult to remove by accident and is made of some type of metal, most assumably steel. The only two things worthy of critique from my perspective are these: 1.The gap in the front between two pieces of the body does not match that of the lines in the back. However, considering the price of this light, that is such a small detail that it does not affect my overall view of the product and the subsequent rating. It's unnoticeable if you're not looking for it. 2. The brightest setting is bright, the lowest setting is dimmer, but looks very similar after your eyes have adjusted. The K18 has a third setting that goes low enough to read a book with in an unlit environment. Reading white pages in the same setting with the K1 will hurt your eyes eventually. If Ultratac needed to make an improvement on this light, having a much dimmer setting would be optimal. It’s a good every carry. The lack of dimness makes it less desirable by way of versatility, but I find the value to be in the brightness, durability, and size.

Perfect size for EDC, doesn’t take up much room in your pocket. Very bright for its size and well made. High recommend.

a good little flashlight takes a real AAA battery that you replace rechargeable ends up dying faster and faster I would definitely buy another one

This is as compact as you can get with a AAA flashlight. Very bright for a AAA. Nice tail cap switch.

So, I bought this a year ago and really loved it. The build quality is incredible. It seems well made and able to survive a nuclear explosion. The light is fantastic! Incredibly bright. On on little AAA battery, this thing will light up spaces to near daylight levels. The design is also excellent. The on and off button is at the bottom, covered in rubber, easy to use, and convenient. Then, it all went to hell. As expected, the light stopped coming on one day, and so I dutifully removed the cap to get the battery out to replace it. I use the flashlight so often that I couldn’t be without it. I had to change the battery immediately. Unfortunately, the battery couldn’t be removed. It appears that, long ago, the battery may have exploded in the case of the flashlight, and got stuck inside. So, despite being one of the best mini-flashlights I had ever used, it had quickly become useless to me. There’s not much point in buying a flashlight if it can’t be reused. From what I can tell, this may be a design flaw. Something about the way the case is designed, causes good battery to become engorged, and then stuck to the interior of the case. It’s too bad, but it means I can’t recommend this. Back to the drawing board for me.

This is a good mini flashlight that has surprising brightness for its size. The beam is well focused so it is almost a spot light compared to other AAA lights I have. This makes it very usable for seeing ahead where you may need to see terrain issues in a hazardous area and you don't have anything else available. It is not too focused either where you only see what is directly in front of you. Perfectly designed optics is what sets this apart and I like the push button on off.
