Features of a Flashlight

A flashlight or torch is a portable hand-held electric lamp. Formerly, the light source typically was a miniature incandescent light bulb, but these have been displaced by light-emitting diodes since the mid-2000s.

The three main features for a flashlight are Dimensions, Battery, and Light. Each of these characteristics are very important when it comes to selecting a flashlight.

Flashlights are used as a light source outdoors, in places without permanently installed lighting, during power outages, or when a portable light source is needed.
