The name "flashlight" has a funny background. In the early days of the dry cell, the power of a dry cell battery was very restricted. To save the dry cell from releasing quickly, the flashlight was operated periodically and simply long enough to have a look at the environments, thus 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 gun light and so on

. The dry cell flashlight is the most basic design and used in many homes and consists of dry cells to power the electrical bulb.

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

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

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 gun light etc

. The dry cell flashlight is the simplest style and utilized in a lot of 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 totally free. Undersea type is a special flashlight, which is utilized for illuminating underwater things and is water resistant.
