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! Review: Best pocket flashlight - 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.

The light pulses are very bright, and I'm sure blinding in the dark. The light itself is very convenient because of it's size and brightness. To get to the Strobe feature you have to cycle through the two flashlight modes. Not a problem because they are blinding, also. **Q: does it zoom in/out** A: No zoom , has hi, low and strobe...my favorite edc light!!! **Q: Where dies the o ring go?** A: The O ring is on the flashlight, and the spare O ring is in the package. **Q: Can you reverse the clip to fit on your cap?** A: Yes! The clip pops off and you can turn it around ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fantastic *by E***S on August 9, 2023* 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!

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. ### ⭐⭐⭐⭐ Durable, great for EDC, not dim enough on low setting. *by D***A on February 2, 2023* 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. ## Frequently Bought Together - UltraTac K1 180LM Ultra-Bright LED Keychain Flashlight - Waterproof AAA Mini Light with Push Button, Compact Pocket-Sized for EDC, Camping, Hiking, Emergencies & Outdoor Use (Black) - LUMINTOP EDC01 Keychain Flashlight 120 lumens Pocket EDC Flashlights 36 Hours IPX8 Waterproof - EverBrite Mini LED Flashlight High Lumen Keychain EDC Flashlight, Small Pocket Pen-Light for Hurricane Supplies, Camping, Hiking, Emergency, Hunting, 1 AAA Battery(Include), Black --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.de/products/369985392-keychain-flashlight](https://www.desertcart.de/products/369985392-keychain-flashlight) --- *Product available on Desertcart Germany* *Store origin: DE* *Last updated: 2026-08-11*
