Well, I usually would agree you, but in this case, at least with the torches that I have linked, not . I have one of that torches for about long 4 years and still working fine. I know it doesn't give 20.000 lumen, the color temperature it's not bad, but everytining always can improve, and the batteries are 4x18650, an standar nowadays.
I had torches that I paid more than 400 euros than lasted just two years. My dive buddy had two Sola, he paid 800 euros each some years ago. Those ones lasted 2 years, after that time they flooded and the factory simply said that were out of warranty.
