From what I understand, Sofirn would like to use their own driver design and UI instead of a whole new driver to run NarsilM. (Not that they are ruling that out)
Using their own driver and UI helps keep costs down.
They would like to use their new v2.0 ramping mode (maybe even a more refined version), plus 1 or more regular mode groups. I’ll let you know if the give more details on the UI and it’s modes. More than likely it will be a mix of the UI on the SP32A v2.0 and the C8F. I listed both UI’s below.
Here is the ramping mode instructions from their SP32A v2.0. See what you think. Looks pretty good to me. Especially if they tweak it to make it smoother like Narsil.
Group 2: Ramping (takes about 4 seconds)
When the light is in Group 1 (distinct brightness levels), press&hold switch for 3 seconds, it switches to Ramping, the default brightness is xxx lumen (Medium Mode).
When the light is in Group 2 (ramping), Fast click to turn on or turn off (Nice!)
Press&hold the side switch to ramp up and down. It changes direction when ramping again within 1.5 sec; same direction when ramping again after 1.5 sec.
The light flashes two times when it reaches Eco or High.
Double clicks to activate Turbo, one click goes back to the last brightness.
Triple clicks to Strobe, one click goes back to the last brightness.
When the light is OFF, press&hold for 3 seconds, it flashes 2 times and then switches back to Group 1.
