Sofirn SP36 - General Voltage Levels; Links

Lower for your preferred ramp the ceiling and with 3 clicks you can switch to the other ramp, where
you can have full power if you need it.
If you click zero times, the floor or ceiling value doesn’t change. This is great because you can change
just the floor or just the ceiling without reprogramming the other.
The SP36 has a nice candlelight mode, the effect is bigger if you use a diffuser.
Lightning storm is also more fun with a diffuser.

*on these two entries, please note smaller battery sizes (e.g. 16350, 18350) have a bit higher
voltages.
There are also some other interfaces available for this hardware, but it requires the user to flash
different firmware. You can make it work like other brands. However, these are not tested and not
officially supported.
