 LED FlashlightsLED Flashlights - An LED (the acronym for Light-Emitting Diode) is a semiconductor “chip” that converts electrical energy directly into light. An LED is called a solid-state light source because it has no gas or liquid components, as do other flashlight sources. LED Flashlight possess some tremendous advantages over flashlights with incandescent lamps.
First, LED Flashlights can last thousands of hours versus less than fifty hours for high-output incandescent lamps. Second, because LED Flash lights are very robust in construction, and have no mechanically delicate parts such as glass bulbs, filaments, or filament supports, they are extremely resistant to vibration and shock, making them well-suited for the combat environment or for mounting on firearms. Third, LED flashlights produce virtually no invisible infrared radiation, as opposed to incandescent lamps, which emit over 85% of their output as infrared, and therefore LEDs are much more efficient in producing light than incandescent lamps — an important factor for battery-operated flashlights. And fourth, they will emit light over a wide range of power input making LEDs the natural choice for adjustable-output light sources.
