Here's another oddity about the design/build of the Klarus XT20 in that Klarus seems to have made the decision to sell a mixed reflector version (smooth on one side and orange peel on the other). I think this possibly gives the light a slightly better mix of throw and spill...or at least makes the center spot more smooth and well blended.
Oddly, advertising images and descriptions from Klarus indicate two orange peel reflectors, initial reviewers seem to have received all smooth reflectors, and first batch shipments seem to have mixed reflectors like this one.
