I've always wanted a flashlight that performs the way Hollywood's flashlights work. They go investigate a dark basement and whip out a tiny key-chain light that has a beam as strong as the Bat-Signal. Obviously, this is in part due to movie-magic but as flashlight tech improves these High-output small profile lights are beginning to match Hollywood.
There have been several shows/films that have used lights in them that intrigued me. I'll just list a few here and let others comment on ones that they remember. It would also be nice if some more senior flashaholics could throw in on what they think the modern day equivalent to that light would be. (Also, this thread is not about if the movie/show itself is any good. :P)
Tron Legacy: Sam investigates the old arcade with a smaller-than-palm sized flashlight. When he sets it down on the computer at the end of the scene it is all black and about 1 in diameter and 2 in length. (The simplicity of the design makes me thing of some of the HDS pictures Ive seen on here.)
X-Files: Their flashlights were decades ahead of their time. I remember scenes where their handhelds rivaled helicopter searchlights.
Pandorum: Sci-Fi film wherein main character has an extremely small handheld light capable of a strong beam. When he holds the light it is so small that it is encapsulated by his hand as if the beam were merely coming out of his fist.
