The flashlight is of an extremely easy design, it is a relatively new invention. It came into being after the incandescent light bulb and the dry cell was invented.

The name "flashlight" has a humorous background. In the early days of the dry cell, the power of a dry cell battery was really minimal. To conserve the dry cell from discharging quickly, the flashlight was run periodically and just 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, underwater type, rifle or weapon light etc

. The dry cell flashlight is the simplest design and utilized in a lot of households and consists of dry cells to power the electrical bulb.

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

Some utilize solar panels for charging throughout daytime. Electromagnet type uses a clockwork plan or a knob arrangement.

To conserve the dry cell from releasing quickly, the flashlight was run intermittently and simply long enough to inspect out the environments, for this reason 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 lamp type, undersea type, rifle or weapon light and so on

. The dry cell flashlight is the simplest design and used in most households and consists of dry cells to power the electric bulb. A headlamp type has a flashlight on a helmet so that the hands are totally free.
