Motor51 turned me on to the macrostream last year. I love it. So small and 250 lumens. I'll probably buy a 500 just to feed the sickness.
I'll carry it next to my Olight 2000 lumen Baton Pro, which is bit fatter than the macrostream, but...2000...lumens....comfortably...in...my...pocket!!! No need to shoot you in a dark parking lot when I can just burn out your retinas with hellfire!
