I'm personally loving X9R ownership. It's very akin to the feeling I had (& still have) with owning my Canon EOS 1Vs - owning the flagship product and pinnacle of engineering effort, on the part of a company I rate highly. Any LED light is an engineering marvel, because to my mind, LEDs are - even to the mind which can readily comprehend how a heated wire produces light - LEDs are pure witchcraft!!
So then take a company which in my opinion has prioritised quality over everything else - or sought to - and their effort at producing one thing which represents everything they stand for - I'm happy to buy into that (pardon the pun).
I see it as fantastic bang-for-buck - where specifically - I still want high quality of execution, not just an answer lumens-warring.
Actually - this is a case-in-point - where Acebeam need a 'fandle' to pull off their latest creation, this to me points to having gone beyond what is sensible, appropriate and practical, for the state of LED technology today.
Olight had to compromise too, of course - what with a 3-minute step-down - but without that, we're back to sub-8,000 Lumen lights (off the top of my head).
So - in summary - the X9R rocks!
