Energizer is upping flashlight design. They’ve released the Hard Case LED Tactical 2AA 2nd generation handheld light that’s tough enough to work in just about any outdoor environment. It’s specifically built for rough use outdoors in fact.
Don’t worry about dropping it. It can handle 15-foot falls without a problem, and while they were at it they made it waterproof. It uses LEDs of course and can even be powered by a single AA battery. Included are blue, red and green LEDs so you can see various things in the dark.
