No idea how it works..I still haven't received my order that I placed on 4-1-2021
Arrived in the meantime.
Because of the packaging, I had a real unboxing experience.
The lamp met all my expectations.
has not arrived yet
This is a superb flashlight with the best User Interface.
Output power is very good , nice beam, illuminates well. Construction is very good with nice details.
Well done Brinyte!
I am using it every day, it is awesome.
