Sweden have problems with to many wild and shy pigs/boars and in 2009 goverment allowed hunting with lights and food so everybody started to make DIY setups with car batteries,day of switches and LEDs.
Not a hunter myself, and to save me trying to describe this in English,here is a
Google picture link. Useful ideas for spare light in power failures?Use something like this yourself?
I use one of my led lights during power failures, and only hunt pigs in the meat/deli section of supermarkets which are pretty well lit. Car batteries are too much of a pain in the azz to transport/maintain (except for in my car, where they work great)
I saw a German Youtube review of cell phones.Tester said he lived in a country with electricity so saw no use for the inbuilt led flashlight. Since I use my EDC more than ten times a day,I guess his everyday life is different to mine.
