The only similar light I have to compare it to is my Quark AA2 Turbo. From my limited comparisons, my RRT-0 with OP reflector throws virtually equal to the Quark which has a smooth reflector. That's 240 emitter? lumens vs. 206 OTF lumens.
The Quark seems to have slightly more flood which I believe is because of the Quark's larger diameter head.
My comparisons were done using an AW RCR123 in the RRT and L91's in the Quark. I have only ran the RRT briefly with the extender and a AA just to verify it worked.
