This is a re-post from the What did you mod today? thread, where I put some beamshots of a modded Convoy S2 with SMO reflector (vs the previous with OP).
I changed the reflector in my convoy S2 (with S2+ short tube, Led4Power 4-6A driver & spring) and Convoy forward clicky switch) with Osram White Flat 1mm2 ! I liked the beam with the OP reflector, but wanted to try it with SMO.
Here are some pictures, before and after, OP > SMO!
Not sure if this is the best way to show them in gif and side by side, but I hope it works!!
Overall, the beam looks tighter as it should. I need to test it outside yet and see how it performs. Still, this is my “pocket thrower” 
I have some doubts for those who installed this led under a small SMO. Is it normal to get some “rings” or at least a “larger corona” between the hotspot and the spill, or do I need to refine the placement of the gasket+reflector to reduce the artifacts?
Thanks in advance
