What is LED Flashlight ?

A LED flashlight produces light through light emitting diodes (LEDs) rather than an incandescent bulb, making them cooler, more energy efficient and tougher.

The light from a LED flashlight is pure, bright and true and can be seen for up to 1 mile (1.6 kilometers). Unlike incandescent bulbs that produced rings of brighter light within the scope of the beam, LED beams are evenly illuminated, like fluorescent light.

Incandescent light used in traditional flashlights utilizes a filament wire encased in a glass vacuum tube or bulb. When electricity is supplied to the wire from the batteries, the wire glows with heat that produces light. The heat, however, is not only lost energy but it eventually burns out the wire and the bulb must be replaced.

A LED flashlight harnesses light created by an entirely different process. Two types of semiconductor materials are used in a LED: one type that has an abundance of free electrons and the other that has a deficit. When enough energy is supplied in the form of electricity, a threshold is reached that pushes some of the free electrons in the abundant material to jump to the attracting material. When that electron takes its place in the new material a photon or particle of light is released.

The color of the released light is dependent on what kinds of materials are used and how much energy is required for the electrons to make the jump. If a low amount of energy is required the light emitted will be in the infrared or red wavelength. If a comparatively high threshold much be reached, the light emitted will be up in the blue/white wavelength.
