I’m new to this forum and wish with this post to say hello to everyone and a few words about myself .
But first of all, congratulations on a great flashlight forum ! 
Is 52 years ,have bean sick a few years so I do not work and then have all the time in the world to try this as a hobby ….
It all started when I would buy a flashlight to my brother in December 2013 ,started then surfing the net and ended up with …. now comes the …. and…Yes, just this amazing forum !
