World's most affordable solar lamp
Some details of the lamp
The lamp, called the SM100 solar light is said to retail at $5 in Africa. It can run for 8 hours on full charge and can be used on a table, or as a head lamp or strapped to a bicycle.
The need for the lamp
Kerosene lamps are the primary source of lighting for over 600 million people in Africa.
These lamps are expensive to run and data suggests that families spend up to 25% of their income on fuel for these lights.
They also pose the added danger of fires and are polluting.
Inventid said the $5 could be a one-time only investment, helping such families.
