Flashlights
Generally, flashlights are small, portable devices that have a direct
beam of illumination and typically do not require a power source for
operation. They usually are excellent for emergency purposes such as
power outages due to extreme weather or for places that do not have
electrical power such as a campground.
Flashlights typically consist of a line of batteries inside a battery
compartment. Often the battery compartment becomes the handle of the
flashlight. The bottom of the battery compartment is often where the
batteries are inserted for operation. The other side of the battery
compartment usually contains the bulb, which is powered by the batteries
and controlled by a switch placed somewhere along the handle.
Since flashlights typically rely on limited battery power, they are
generally in use for shorter periods than electrically powered lights.
Some factors to consider when purchasing include the brightness of the
bulb, how direct the beam is, and how long the battery life lasts.
