Although I don't have one, I'm sure the M1X will out-throw the DBS with the MC-E pill. The single R2 with the smooth reflector does out-throw the MC-E set-up, but it's a very tightly focused beam.
I have been VERY happy with my MC-E set-up in the DBS. I run it on 2xIMR123's 95% of the time, but do have the extender for if and when I need longer runtime. High doesn't run very long at all on the 2xIMR123's, but for longer use I can always drop it a level to medium which is still over 100 lumens.
And as far as the throw of the MC-E set-up in the DBS goes, it seems about equal to my TK11 R2. The DBS just has a much larger hotspot of course. In total darkness, I can see out past 100 yards with it no problem....and it lights up everything in it's path!
