pealamp

A pealamp is a type of portable electric light, commonly known as a flashlight or torch in other parts of the world. The term "pealamp" is a regional variation, primarily used in certain areas of South Asia, particularly in Bangladesh and parts of India. Its etymology is likely derived from "peal," an archaic English word for a bell, and "lamp," meaning a light source. The association with a bell might stem from the early designs or the sound produced by some older models when operated.

These devices typically consist of a reflective casing, a light bulb (historically incandescent, now often LED), and a power source, usually batteries. They are designed to provide illumination in dark environments and are widely used for personal safety, utility, and recreational purposes. The construction of a pealamp is generally straightforward, allowing for ease of use and portability. They come in various sizes, from small keychains to larger, more powerful units. The widespread availability and affordability of pealamps have made them an essential item for many households, particularly in areas where reliable electricity is not always available. The technology has evolved significantly over the years, with LED pealamps offering greater brightness, energy efficiency, and longer lifespan compared to their incandescent predecessors.
