Though the flashlight is of a very basic design, it is a relatively new invention. It came into being after the incandescent light bulb and the dry cell was created.

The name "flashlight" has an amusing background. In the early days of the dry cell, the power of a dry cell battery was extremely minimal. To save the dry cell from discharging quickly, the flashlight was operated intermittently and simply enough time to examine out the environments, for this reason the name "flashlight".

There are numerous flashlight designs available in the market today. Like dry cell flash lights, rechargeable acid type flashlights, rechargeable dry cell type, LED (Light Emitting Diode) type, solar charging type, electromagnet type, head light type, undersea type, rifle or weapon light and so on

. The dry cell flashlight is the easiest design and utilized in most families and consists of dry cells to power the electric bulb. As the batteries release the illumination dims in these flashlights.

Rather than purchasing a flashlight, which needs battery replacement frequently, a much better style is to utilize rechargeable batteries, which can be lead acid type or dry cell type.

Some use solar panels for charging during daytime. Electromagnet type utilizes a clockwork plan or a check here knob arrangement. In clockwork plan a spring mechanism is utilized to power the flashlight and has to be wound as needed. The knob type plan has a moving coil or magnet which moves when the knob is pressed and charges a capacitor, which supplies power to the bulb.

LED type flashlights are of a recent style. Though LED: s have been around for years, the LED flashlight was not offered till late 90s because the LED: s could not be run constantly and their luminosity was really poor.

LED flashlights consume hardly any power compared to the conventional electric bulb as LED: s do not produce as much heat as electrical bulb. LED flashlights usually have a metal body to dissipate heat by conduction given that LED: s do not dissipate heat through the light beam like electric bulbs do.

A headlamp type has a flashlight on a helmet so that the hands are complimentary. Underwater type is an unique flashlight, which is used for illuminating undersea objects and is waterproof. Rifle or weapon lights are unique flashlights utilized for illumination of target.

Flashlights are offered and relatively low-cost in attractive designs. The cost varieties from a few dollars to a couple of hundred dollars.


To save the dry cell from releasing rapidly, the flashlight was run periodically and simply long enough to check out the environments, hence the name "flashlight".

Like dry cell flash lights, rechargeable acid type flashlights, rechargeable dry cell type, LED (Light Emitting Diode) type, solar charging type, electromagnet type, head light type, undersea type, rifle or weapon light and so on

. The dry cell flashlight is the most basic style and utilized in most households and consists of dry cells to power the electrical bulb. A headlamp type has a flashlight on a helmet so that the hands are free. Undersea type is an unique flashlight, which is utilized for illuminating undersea objects and is water resistant.
