That is an impressive light and some of the guys will prefer it, for one thing, 180 lumens on bright is very cool.
I prefer the key chain light and regular batteries instead of the more expensive type batteries, the one in post 5 is great for that.

That’s pretty much why I chose that one. It is not keychain tiny, but small enough to carry in a pocket. Working the tailcap on/off switch took me a while to master, but I figure this beast has already paid for itself.
Plus you could put somebody’s eye out with it, I guess, in a pinch. Easier to carry than a MiniMag, one-hand operation, bright enough to hurt your eyes, and it’s Streamlight. What’s not to like?
