SUREFIRE EDC FLASHLIGHTS BACK(UP) STORY
SureFire pioneered the compact high-output flashlight when it introduced the 6C back in 1988. It was a game-changing moment for the industry, and the 6C led the way toward multiple innovative flashlight models from SureFire, including E-Series everyday-carry flashlights which arrived at the turn of the millennium.
Since then, evolution took place in the light industry and a lot of things have changed. Enjoy a good read over at the SureFire news page if you want to learn more about it.
