Overview

Meanwhile a huge amount of different solar lamps is introduced to the market. Number of new models increases almost daily. Therefore, it is difficult to find an adequate solar lamp regarding type and quality.

Lamp Types

Today, there is no common typology of lamps yet, but few insititutions refer to the following definitions:

Mini Reading Lamps / Task Lamps

They exist in a variety of size and light output intensity. Mainly they are used for special tasks, such as reading or weaving. Solar Energy Foundation estimates, that most of these lamps available, are not able to replace kerosene lamps due to their minimal brighness.

Flashlights / Torches

Torches have directional, focused light. They are portable and often have an integrated solar module. Solar Energy Foundation deny a replacement of kerosene lamps for torches as well because of minimal brightness and construction: Furthermore, they do not recommend integrated solar modules, because the module is not large enough to gain enough capacity and the battery is likely to be damaged, when placed outside by the sun, dust or rain. Additionally theft may be encouraged.



Lanterns
