About the product
The Little Sun solar-powered lamp was developed by artist Olafur Eliasson and engineer Frederik Ottesen in early 2012 as a way to get clean, affordable light to the 1.6 billion people worldwide without access to electricity.
Little Sun is now being sold in seven African countries: Zimbabwe, Kenya, Ethiopia, Burundi, Senegal, Uganda, and South Africa, as well as in the EU, Canada, Australia, Japan, and the USA. It is a high quality, attractive LED powered lamp.
Cost- The cost in Europe is €22. In more developed nations its 25 Dollars or 20 euros
It is a global product connecting the world through sharing light.
I think this product is both effective because it does what is says and is good for the environment and it is also very attractive and makes a big impact on poverty stricken nations.
