Its use is for security purposes.
Its features:
1) It withstands tough use.
2) With the right batteries, such as INR21700-50E, it has a full intensity autonomy of over an hour and a half (not referring to continuous use, as I haven't tested it continuously).
3) With its zoom, it reaches distances of over 500-600 meters, where you can distinguish its illumination. And about 100-200 meters where you can clearly see the object and the area it illuminates.
4) It can be easily repaired, as even its LED can be easily replaced, maybe even with a more powerful LED. Even if it falls, as it has happened to me several times so far, and the zoom starts to play up, it opens from the front and you can easily tighten it to eliminate any looseness.
5) It is advisable to use a magnetic cable for charging, especially when using it daily and charging it. Otherwise, be careful when inserting the cable and supporting the flashlight during charging to avoid damaging the plug. Also, its batteries can easily be inserted and removed for proper charging in an external charger (if you do this, you should get batteries with a protruding head, not like the ones I have used with a small modification).
6) With the zoom completely closed, it illuminates a huge radius/opening at a distance of 5-10 meters, leaving nothing hidden in the darkness in front of you.
7) It is very affordable in the market, so if you calculate the cost of the right batteries, with 30-35 euros you have a brightness similar to buying a flashlight of 80+ euros.
8) It is very durable and has the appropriate weight, even for a strong impact despite its relatively small length.
9) You will see in my own review a camera mount that I have attached to it, which records possible "thermal incidents" so that we don't have to prove that we are not elephants at some point. This mount is, of course, extra and is not included with this flashlight.
10) If someone looks directly at the LED depending on the exposure time and the distance from the flashlight, it will take a few seconds to 2-3 minutes for their vision to return to normal and see the environment again.
All the things I mentioned have been confirmed through professional use of this flashlight, but it certainly works perfectly for personal use as well!
