A flashlight, also called a torch is a portable device used for illumination and usually has battery cells for power. A flashlight usually consists of a small electric light bulb, a compartment for batteries which power the bulb, a switch for the bulb and a parabolic reflector for focusing the light. The name "flashlight" has a humorous background. There are many 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 lamp type, underwater type, rifle or gun light etc.
The flashlight is the simplest design and used in most households and consists of batteries to power the electric bulb. As the batteries discharge the illumination dims in these flashlights.
Rather than buying a flashlight, which needs battery replacement frequently, a better design is to use rechargeable batteries, which can be lead acid type or dry cell type.
Electromagnet type uses a clockwork arrangement or a knob arrangement. LED type flashlights are of a recent design. LED flashlights consume very little power compared to the conventional electric bulb as LED:s do not produce as much heat as electric bulb. Rifle or gun lights are special flashlights used for illumination of target.
