Just watched the movie and found a surefire in action, used by the lead actor.
Going through hell and saving lives with the SF M3 T and Z45.
I want one now!
A search for "poseidon" shows that there are already a few threads about the flashlights in this movie. On top of that, none of them should have been started, as there's already a thread about flashlights in TV shows and movies in the "Threads of Interest" sticky in the General Flashlight Discussion forum.
