I have these questions too, on some Singfire 18650 lamps.
Same chips
CX2829.
MEM2309 1247
The modes of my drivers are: 5, no memory: High 100%, Medium , Low , Fast strobe, SOS.
both boards have identical brightness output by eye driving XML T6 emitters
I too would like to get rid of Strobe and SOS, Ideally add last mode memory too. or a least have low com on first.
Probably just as easy to swap out the driver board, but would like to know if surgery on these is possible.
The thread with more info on these lights is here
16mm board
20mm board
