I received the X1R I ordered a few weeks ago. Nothing is mentioned about CR123 or low voltage cutoff in the pamphlet it came with.
I tried some single used CR123 with resting voltage of around 2.65V and no go. I discharged a 18650 using the low mode, and after the light shut off, the resting voltage was 2.75V. I imagine the cutoff voltage is 2.7V which kinda sucks, I was hoping to use this headlamp in winter with single CR123s.
Has anyone here tried to use the X1R with CR123?
