Huynhie, I started a nice collection of Surefires and other torches before I got into photography. One day, I listed what I spent on illumination tools in a spreadsheet, the four figure sum made me not keep track of my spendings anymore.
I can tell you, NOTHING will prepare you for the brightness of these Surefires. Most of the lineup are smaller than the Mini-Mag; but have light outputs
EXCEEDING the 4 cell (4D/4C)
models.
I regularly carry the Surefire G2 nitrolon
model in my camera bag. I also have the 9P
model equipped with an Z32 shock isolated bezel. It places the lamps in rubber suspension that is designed to withstand the recoil from a 12 gauge blast (has anyone shot with a shotgun felt the recoil?) All the gun mounted lights on the M4 carbines and backup sidearms carried by the US and coalition troops currently in Iraq are Surefires, equiped with similar shock isolated systems.
For the most part, they are tactical illumination tools. Designed for serious urban warfare. They feature what's unofficially the "dead man's switch": when the person carrying the torch falls dead, the light switches off to prevent illuminating their peers in proximity to prevent compromising their lives. When the engineering criteria stretches as far as considering what happens when the operator falls dead - nobody's kidding around!
There's also Tigerlight (

model.
Mate, I could enlighten anyone for days about torches...
