LED flashlights can do more than just light your way, they can save your life.
Given the low power requirements and small physical size of LEDs, flashlight manufacturers have been able to abandon the bulk and fragility of traditional torch models, and are now freely exploring more lightweight, rugged and feature-rich designs. Especially appealing are the newer flashlights crafted from military-grade aircraft aluminum, with scalloped crowns that can be used to break glass or knock an assailant out cold.
As you'd imagine, police, military personnel, and outdoor enthusiasts are all crazy about these heavy-duty LED flashlights. And so are we -- I looked at a quartet of diverse flashlight models, each weighing a pound or less, but each equally capable of delivering a brilliant beam or a deadly blow.
