Theres something wrong with the Led Lenser P14 in the video.. "can hardly see it" at distance of 15-20 meters, eh?
Maybe he's using it on low, or the LED has been damaged..
Oh, and LL P14 uses 4x AA batteries, not 4x AAA like the video says.
Led Lenser and Coast are not the same company.
Led Lenser is German company that makes the Led Lenser flashlights. It was bought by Leatherman some time ago, if I remember correctly.
Coast is american company, that used to import Led Lensers in to USA, and rebrand them there. Nowadays Coast is making their own lights that look like Led Lenser lights with some small differences.
