As a kid I always had a fascination with knives and flashlights. That rabbit hole is pretty deep as well and I've managed to stay out of it. I have a handful of cheap chinese knockoff flashlights from dealextreme.com (I do love this site a lot!) and I don't know how they compare with the real expensive stuff but they are far and away the best flashlights I've ever seen or used.
These are the two I have left:
One of them lights up the entire front lawn and the other throws a far and precise beam.
I don't know much about flashlights and I try to keep it that way otherwise its easy to get sucked into another expensive hobby, but at times I find myself browsing flashlights and watching youtube videos for hours.
