I just read the OP again, and it says that the lantern is expected to use a Nanjg/Qlite driver. If so, it wouldn’t actually be compatible with Narsil. To make it so would add a bit of manufacturing cost. Whether that would translate to a higher price for us, I don’t know.
Sorry if I’ve added confusion to this project. :person_facepalming:
The prototype has a Qlite driver, the production model can very easily by built using the Narsil driver, (only with the maximum output amps reduced for longer run times, & probably would be more feasible if the lantern lower body is designed around the Q8 body, (and not the SRK body)
