The flashlight is very powerful, but the 9,500 lumens only last for 8 seconds. After that, the brightness decreases. I have had it for 4 months, and it has been used for a maximum of 10 shifts, and the first three brightness levels stopped working. I always kept it in a case, and the flashlight doesn't have a single scratch. For a flashlight that costs 179€, I would expect better build quality. It is unacceptable for it to stop functioning after only 4 months of use, especially when it has only been used for 10 shifts. Of course, I will contact the company regarding the warranty they provide for the product.
***1st Update: They replaced the flashlight with a new one at the authorized store where I purchased it, but after 5 months of minimal use, the last time I used it, it wouldn't turn off. It has been continuously on for the past 10 days. I will take it back to the store where I bought it. I do not recommend it to anyone. I had it as a second flashlight for complete darkness. It was used very little and it is malfunctioning for the second time. Choose a different model instead.
***2nd Update: I took it to the store where I bought it for the second time, as it hadn't even been a year since the first purchase, and Nitecore replaced it with a new one for the second time. This is the third flashlight I have received as a replacement, but the specific model they gave me has the upgraded lock function. The previous models I had did not have this feature.
I purchased the first flashlight in September 2020, and its manufacturing date was 2017 (according to the serial number).
The first replacement due to malfunction was done in May 2021 (I encountered a problem in January, but due to store closures for the pandemic, the replacement was done in May) with a new flashlight from the distributor. The new flashlight they gave me as a replacement in May 2021 had a manufacturing date of 2018.
The second replacement of the flashlight due to malfunction was done in November 2021, with the updated version of the new flashlight, and the manufacturing date of the flashlight they gave me was June 2021.
I hope this time it doesn't have any issues.
The service and the distributor worked perfectly.
The plus side is the 2-year warranty and 5 years for labor.
P.S.: I have worked with many tactical flashlights due to my job in the Special Forces, and for me, Nitecore is among the top companies along with Olight.
I will simply choose a flashlight with a detachable battery for my next one, not an integrated one like this, because I encountered a problem.

It is perfect for close range. Great range, covers a large area. Especially in turbo mode, it is incredible. Of course, it only lasts for 7 seconds, but what can we do. The battery life is very satisfactory. Quality-wise, NiteCore is a guarantee. However, you should know that the beam doesn't reach far. It is not adjustable. You need to know what purpose you will choose it for because it is not cheap! If you want something for long range (over 150m), get something else.

The lens is very powerful with amazing diffusion up to 100 meters maximum. Its negatives are that in its maximum operation, the button does not stay pressed and it requires gloves due to excessive overheating. Additionally, its battery is fixed like mobile phones, if it breaks, you have to send it to the company.
