The Little Sun solar powered lamp was designed by Icelandic artist Olafur Eliasson and solar engineer Frederik Ottesen and first launched in 2012. Made from yellow coloured acrylonitrile butadiene styrene (ABS), its design was inspired by the Ethiopian meskel flower (a national symbol of positivity and beauty) in consultation with users in Africa. Chargeable in any weather, 5 hours of bright sunshine can produce up to 50 hours of soft light and it is provided with a detachable lanyard to allow the user to wear the lamp around the neck. Originally intended for people who have limited access to a reliable source of energy, the lamps are now sold worldwide with profits used to subsidise their cost to poorer communities as well as support the company's health, education and livelihood initiatives. Little Sun also works with international organisations and the UN to deliver solar lights for disaster relief efforts.
