LED Flashlights employ a Light-Emitting Diode, which is a semiconductor chip that converts electrical energy into light. As there is no gas or liquid component in these lights, they're often referred to as solid state, which is part of why they're so unbelievably durable. Since electricity is converted directly to light, an LED Flashlight is also far more efficient, so you'll get a lot more battery life than from a traditional incandescent bulb. All this great performance means you'll have an incredibly tough flashlight that lasts a long time! LED Lights are good for a number of different activities, from military operations and hunting trips to general use around the house.
