Has anyone reprogrammed a Sofirn D25S headlamp?

I don’t even know if this is a thing, but I’m wondering if anyone has reflashed different firmware onto this headlamp, or something similar.

I love this headlamp. Super bright. Not too wide, not too tight. Nice big battery and longevity. But the lowest setting is like 2-4x brighter than I’d like from a headlamp. I need a moonlight setting to read a book by.

Any knowledge about this and whether it’s been addressed before? Either an updated product I’ve not heard about, or if someone has modded it to introduce a lower setting?

I don’t think it can be reprogrammed. Changing the range usually requires a different driver. So you would need a new driver anyway.

Before covid, war and semiconductor shortage I made many different drivers for this this kind of host. Here is a FET +1+3 with Anduril UI
