Judging by those photos above, the throw to be somewhere in line with the X45 (maybe slightly less) so yh that 800m rating seems off. Even if it manages about 650m that’s still be good for such a powerful light of this size.
May be more in the range of 600 meters depending on the real lumens output if it is close to the advertised 40 000 lumens. I doubt the 800 meter range. Imalent DX80 measured just over 700 meter with a 92 mm head and around 29000 lumens. X50 has got a 75 mm head.
Both of them are official Acebeam retailers in Germany and if I am not totally mistaken they can ship flashlights to Italy, too. I am not sure if they can ship lights with replaceable batteries but as X50 comes with an integrated battery pack I would feel optimistic. ;)
Measured 958 lux at 10 meter distance which give an intensity of 95.8 Kcd. This is 619 meter throw and not the advertised 800 meter max. Ceiling bounce was 2414 lux compared to 1644 lux for my X80GT.
I will say yes. As I can remember the vn is 31000 lumens. My X80GT close to 28000 lumens has no modification but I must say the X50 is definitely much better with throw and as well much better with the lumens output.
