It's been more than 100 years since the first handheld flashlight was first invented. In the development of incandescent bulbs developed the idea of creating an instrument that could provide portable light sources. There were numerous, obvious applications of such devices, if it could be created in a practical manner.

The issue was finding the right solution to provide power to such devices. There were batteries, however they were very heavy and their electrolytes in liquid form were susceptible to spills and leakage. The solution came in 1890's, when the first dry cells were invented. They used an electrolyte in a paste form that was strong, durable and didn't spill and could be used in any position.

A short time later the invention, an English inventor by the name of David Misell patented a device that contained two of these dry cell batteries together inside a thick tube of paper, which was capped at the other side with a small incandescent lamp that was positioned above an engraved metal reflector ring. It is the very first lightbulb. The term "flashlight" is derived due to the fact that these earlier devices to produce a constant illumination due to the nature of the zinc-carbon batteries, which required to rest between use periods which is why the word flashlight. Although they were useful, primitive flashlights were not sufficient for daily use. This changed in the 1920's thanks to advances in battery technology as well as the introduction in the more powerful tungsten. With improved effectiveness and battery technology that was able to supply constant illumination using a handheld flashlight increased significantly.

Despite constant improvement in performance and numerous modifications to the design of the Imalent flashlight remained unchanged during the following seventy years. It consisted of an assortment of battery packs, an electronic switch as well as an incandescent bulb. It wasn't until 1990 that flashlights would undergo an important change with it was the time to the LED which is also called Light Emitting Diode. Traditional flashlights use an incandescent lamp that warms up a suspended filament until it turns into a glowing. There is a lot energy generated when the filament glows and emits its yellow-colored light. This process requires a lot of battery usage and is not efficient particularly over the lifetime that batteries. The light that is produced will change dim and dim as batteries deplete.

It is the Light Emitting Diode (LED)utilizes a charged semi-conductor enclosed in a clear resin to create the light. The light is produced when an electrical charge alters the chemical state of the substance through the exchange of electrons.This extremely efficient process creates a brighter illumination than traditional flashlights. The solid resin cover of the LED helps to shield the LED from damage and improve its longevity.
