Liter of Light is a global open source movement with the aim to provide an ecologically and economically sustainable source of light to underprivileged households that do not have access to electricity or are unable to afford it. The plastic bottles and the other materials used in the technology are easily available eliminating the need for energy-intensive processes involved in gathering, manufacturing and transporting new bottles. Coupled with the simple assembly, this means that even people in the most deprived neighborhoods can install and enjoy the benefits that are associated with access to better lighting. The affordability of the technology means that the majority of slum households can install it with the assistance of entrepreneurs in the informal settlements who stand to benefit from having a new source of income.
