I was just thinking, it's really not that long ago when you'd have to fork over a pretty serious wad of cash to get an expensive Surefire brand flashlight that required expensive CR123 batteries which was marketed as "tactical" because anything over 30 lumens was considered "tactical" by them. And here we are talking about a $16 Thrunite keychain light that can do 60 lumens on a common 1xAAA battery. Pretty darn amazing how far we've come with flashlights.
