Although a flashlight is a relatively simple household device, its invention did not occur until the late 19^th century. Conrad Hubert was the first person to come up with such an idea and many other inventors later developed on the concept. A flashlight is basically a handheld portable device which enables one to overcome simple, mundane, daily chores with greater ease. A flashlight is made up of reflectors, electric batteries & is operated by a power switch. An LED (Light Emitting Diode) flashlight is a special form of flashlight that is more durable & powerful than an ordinary flashlight. In recent times, LED flashlights have found usage in various purposes. LED Flashlight are nowadays used in cameras, in miner’s caps etc. Even a few years back the concept of LED flashlights was not very popular. But gradually these LED flashlights have been proved to be even more efficient & power-saving than conventional incandescent lamps. The main reason behind this is that LED flashlights have a longer battery life & are also less fragile than a conventional incandescent lamp. It is mainly due to this specific reason that LED flashlights are nowadays being permanently installed in many places like stadium, railway stations etc. Moreover, the color spectrum of LED Flashlight is different from the conventional incandescent lamps. These LED flashlights cast a white beam of light which is not only stronger than the conventional incandescent lamps but also help in better viewing especially in the darkness. LED flashlights are becoming increasingly popular in vehicles as well as they help in better vision particularly in the highways in the darkness. Moreover, as LED flashlights are cheaper & hence easier to afford, they are used by night-watchmen & security guards alike. Technology has advanced to such a level that nowadays LED flashlights, powered by lithium coin batteries are being used to illuminate watches mainly those glow-in-the-dark types of watches. Apart from that, these LED flashlights are also used in diving headgears & miners caps because of their durability & water resistant capability. A very important characteristic of LED flashlights is that they are non inflammable. No wonder these LED flashlights are being increasingly used in inspection of areas full of flammable gaseous particles. The designs of the LED flashlights are sleek & compact. Hence they are easily portable, sufficiently powerful & durable. These LED flashlights are your best companion when you leave your house late at night. As these LED flashlights can be easily rechargeable, they are a popular pick for the adventure lovers, trekkers, etc. It is no wonder why LED flashlights have become this popular in so short a span of time. That these LED flashlights are indeed an outstanding invention of modern times cannot be doubted.
