Tired of replacing the old batteries on your flashlight? Try one of the new LED Flashlights. They're small, bright and thrifty! Infinity makes an excellent (and almost indestructible) portable model that provides light from a single AA-cell for up to 40 hours! Or try the cool Photon Microlight keychains, for up to 12 hour of continuous usage on 2-Lithium type batteries. If you're into hiking, not having to carry extra batteries is certainly something you'll like.
