subject: Led Flashlights Vs Ordinary Flashlights [print this page] Light emitting diodes, or commonly known as LEDs, have been around in all sorts of devices. You have seen them around in traffic lights, watches, remote controls, television sets, etc. Flashlights are a typical example of this - using new technology in old products. If they are becoming so popular what are the advantages of LEDs over traditional bulbs?
Unlike ordinary incandescent bulbs, LEDs are illuminated by the movement of electrons, and do not have a filament that will burn out. As a result, they do not heat up easily, but still last just as long, or even longer, than a standard bulb, making them safe for use in a tent or other enclosed space.
This difference contributes to the main advantage of LEDs: efficiency. The traditional process producing light of conventional incandescent bulbs involves heating up the filament until light is given out. This process is highly inefficient, as it generates a lot of unnecessary heat. This heat does not produce any light, and the energy needed to produce that heat also drains your batteries.
LEDs, on the other hand, generate relatively little heat. More of the power from your batteries goes to producing actual light, which means you get to use smaller batteries, or enjoy longer battery life.
The more compact LED is another advantage in that it allows for Led flashlights with smaller form factors. And unlike traditional flashlights, LED flashlights also do not force your eyes to re-adjust to the darkness every time you use them.
LED's also have much better resistance to shock and impact. I've heard several stories about LED flashlights being dropped from six feet or better on to concrete and the LED was unharmed, although some of the flashlight cases didn't survive the experience...
LED torches are simply are simply amazing. Small, lightweight, and powerful to the point of blinding, they are revolutionizing how we use flashlights. If you ever find yourself needing a flashlight that offers you bright light with dependable use, then led flashlight is the best one that you are looking for.
