The new SF37 is a triple-emitter, 2s 18650 light with a tail switch.
The listing says:
It looks like they are 5050 emitters. If the reflector spacing is the same as the C8F, then selling the MCPCBs separately would make it a lot easier to have a 3x SST-40 C8F 
The leds are chinese would-be XM-L’s and the user interface is ancient. If it was not new I would have thought it was a very old model. It would be a lucky thing if the MCPCB was of the DTP-type, but who knows? 
It’s apparently their version of the 3800, made by a few brands. Nice light, aged UI, has a lot of potential.
Yeah, it struck me as rather odd and old.
Good point that the MCPCB unlikely to be DTP.
