This could go in general discussions, but I would never read it there. So I post the question to the Virginia Forum which I do look at most everyday: Do you carry a flashlight for any "tactical" use and what do you carry? I generally have a cheap but very bright Ultrafire XML-T6 on me for workday use. It has 3 levels of illumination plus SOS and strobe. In my work a flashlight is very handy but my choice gives me some "tactical" uses. For airline travel I always carry a different variety that is smaller but similar.
