An LED lantern for battery operated lamps: A prototype

This article is a part of a series about the design of small, battery-operated lamps, and a project in India.

For more, see the “Artificial lighting for small devices” series. 

In India, many manufacturers are developing lanterns that use LEDs and other energy-saving technologies. 

The lamp is also known as a LED lamp, and the LED light source has been used to make lighting in the homes of some people. 

But LED lanterns are not necessarily battery operated. 

Here are the basics of LED lighting: The primary power source for the lamp is a battery that contains LEDs.

The lamp then turns on, and on, producing a light output of about 20 lumens per square meter. 

There are two types of lamps, both of which use a single light source to produce light. 

For the most part, this light source is a high-powered LED light bulb. 

A low-powered source (called a single-lamp source) produces light using the same electrical process. 

Lamps with a single source are called single-solar, and they typically use batteries with a capacity of less than 30 percent of the capacity of a single bulb.
