2 adjustable levels of LED light, Sunpower solar cells, includes 3 AAA rechargeable batteries, ROHS and ISO certified; design: Olafur Eliasson and Frederik Ottesen
This “little sun”, which is powered by solar cells, was developed by the artist Olafur Eliasson and the engineer Frederik Ottesen. Their goal was, and is, to create a clean, affordable, reliable, and portable light source for the over one billion people in the world who do not have consistently available electricity. As a result, Little Sun is being sold in ever more African countries – and this at a lower price than in Central Europe. The higher margin in the latter makes possible the lower price in the former which then underpins the establishment of a business network that reaches into out-of-the-way places. In the meantime, Little Sun is also creating local jobs and allowing profits to be made.
On the one hand, Little Sun is a functioning LED light source that is powered by extremely efficient solar cells in conjunction with AAA rechargeable batteries; on the other hand it is a device whose every detail has been carefully designed and whose uses covers a broad spectrum. It is suitable for use both indoors and outdoors because it is weatherproof (although not waterproof – so don´t take in the bathtub with you!). The batteries will charge even when the sky is cloudy; it will of course just take a somewhat longer time. Five hours of charging time in the sun produces 10 hours of soft light (level 1) or 4 hours of bright light (level 2).
Also note: During charging, it is best to turn the light off if possible. More information about the project including a video about the lamp can be found at: http://www.littlesun.com.
