National Geographic's Steve Casimiro has a blog with some very neat advice on outdoor gear. The review of this compact spotlight reminded me of the definition of a flashlight: a device for holding dead batteries. An excerpt:
But then I discovered Surefire’s M3LT ($550) and whoa, nelly. This “combat light” pumps out a shockingly bright 400 lumens. On a trip last week through Utah’s canyon country, I used it repeatedly to suss out camp spots, search for the trail ahead, and illuminate the North Rim of the Grand Canyon way over in Arizona. Indeed, the M3LT is so bright, you could easily use it for self-defense—just point and click and that attacking grizzly would be blinded. I’m not kidding.
