IMO a missed opportunity to propose something truly innovative, the launch performance of XHP50.3 is not so good, just look at the RS50 (to stay in the family), on average 30% worse than an SFT40 even if with a higher number of lumens, moreover it has performances too similar to the MR90 which costs much less and is much more versatile, I would have proposed instead of XHP50.3 an SFT70 that would have increased the launch without penalizing the lumens or at the limit I would have preferred XHP70.3 to be superior to Acebeam X75, so instead this lamp is neither meat nor fish ...
