9x are NKON's from today's delivery, the other ones are ... others *g* (E10, ES12, A3T, LD01). the black E09 is a 2011 build and serves me great as baseball cap light with the LD01 pocket clip
i'll sample brightness and beam pattern later. am wondering if the OP reflector makes a difference.
Just to add more confusion, my rose E09 from Tank007 has serial 207 but the body is mismatched tonally. The head assembly and PCB are the same as my black E09 from Banggood (from DE warehouse), i.e. OP reflector, minimal epoxy glue used, no insulator between emitter and reflector, no R5 resistor.
The late 2013 OP reflector really does wonders to the original beam (2012 SMO reflector, artifacts in hotspot and corona, starry-ness), the beam pattern looks great now, about similar to Thrunite Ti XP-E. I am keeping my old E09's for the higher throw tho.
In general, SMO reflector outputs look slightly brighter to my eyes than OP reflector outputs.
