The higher efficiency of LED flashlight serves a very important purpose.

LED lighting has stepped well into our lives. People are already envisioning affordable as well as energy efficient LED lamps in all homes. There are various reasons why we need a flashlight. This is a highly portable and battery operated source of light that is made use of in order to illuminate a task. Different levels of light will be required by different tasks.

Some people require a LED flashlight in order to see the close by or immediate area. This is required in order to move around,The era of LED flashlight is here Articles especially at campsite, during night walks, or inside a dark home. The minimum requirement from a LED flashlight in this case would be enough light in order to recognize small objects. No kind of colour recognition will be required in this case.

In addition, light from a LED flashlight will be required for reading, colour recognition as well as for close-up tasks. Sometimes the LED flashlight is required for illuminating a much wider area for conducting searches, or in case of large groups. The LED flashlight is also required for spotlighting the distant objects in a way to recognize them. Each of these tasks will need a different type of LED flashlight.

Earlier the flashlights consisted of an incandescent bulb, besides a set of batteries, along with a switch. Next, there used to be a holder for all these components. Next came the practical white LED. This replaced the incandescent bulb and brought about a revolution in flashlights. This was because there was so much difference between the LED and the incandescent bulb. The bulbs depended on a filament that was heated to incandescence. These produce both light as well as heat. On the other hand, the LED produces light by changing the energy state. A lot of light is produced but very little of heat. This is why the LED flashlight is much cooler to handle as compared to any other type of flashlight.

The filament of a bulb is susceptible to breakage can be due to shock. This can happen due to dropping of the light or it getting knocked against an object. The LEDs in a LED flashlight have been encapsulated in clear epoxy. This is why they would be shockproof. Even if you drop it, there will be no damage.

An average bulb typically lasts for about 6 hours before it gets burned out. The LEDs typically last for about 100,000 hours. This is about 11 years of continuous lighting.
