I have the XR-E (Q5) version of the C8 and I measured the centre beam distance at 183~ metres and that was in normal street lit conditions at night so in total darkness it will be even more. And that was with the stock reflector, add a bit more for the better quality aluminium reflecvtor I guess!
So that XM-L will be even further![]()
Hence the issue. The dynamics of beam geometry are a bit complex, but suffice to say, while there's four times as much light, it's coming from a source more than four times the size. because of this, the same reflector will create a beam with greater divergence which will result in less throw.
Remember that while a torch may be able to launch the same amount of light as far as a tighter-beamed light, if it has a much wider beam you wouldn't be able to see it because closer objects will drown out the furthest because they'll be lit more intensely.
