A LED flashlight is able to produce light with the help of light emitting diodes, or the LEDs. There is no incandescent bulb being used here.

A LED flashlight is able to harness light that is created by a different process. There are two distinct types of semiconductor materials that are used in this LED flashlight. While one type will be having an abundance of free electrons,The functioning of the LED flashlight Articles the other one will be having a deficit of them. Once it gets enough energy in the form of electricity, it will reach a threshold. This will push a few of the free electrons present in the abundant material to jump into the side that has a deficit. When this electron has taken its place in the new material, there will be a photon or a particle of light that will be released.

This released light will be in a colour that will depend on the kind of material that is being used. The LED flashlight comes in many different sizes as well as candle powers. It is the number of LEDs present in a flashlight that will determine its brightness. The LEDs in a LED flashlight are coated with a clear resin that makes them virtually indestructible. This means that in case you drop a LED flashlight, chances are that no damage will take place. Many models of the LED flashlight are waterproof too.

In terms of power consumption, LED flashlight uses only 5-10% of the power that is used by an equivalent light bulb. This way it helps to conserve batteries and saves money. The LED flashlight has a long life and can stand up to 5 to 10 years of continual use. 

The light that you get from a LED flashlight will be pure and bright. In fact you would be able to see it for up to 1 mile. On the other hand, the incandescent bulbs produce rings of bright light which are within the scope of the beam. Also, the LED beams of light are evenly illuminated, just like the fluorescent light.

There are certain types of LED flashlight that do not even require batteries. In such models, a copper wire will be encased in a magnetic field that will be inside the flashlight. You only need to shake the LED flashlight vigorously for 15 to 30 seconds. This is enough to generate electricity that will produce light for about 5 minutes. In case you need light beyond this period, you only need to shake the LED flashlight again. This product contains no replaceable parts and is a great option as an emergency light.
