Liter of Light


Liter of Light redesigns solar lighting for the developing world. Our simple, two-step technology creates local jobs, teaches green skills, and empowers energy-poor communities. Rather than depending on imported, patented, and expensive technologies, our grassroots green lighting movement embodies the principle that anyone can become a solar engineer. Through producing easily repairable solar lights with locally available parts, Liter of Light increases communities’ self-reliance by integrating a livelihood model with the capacity to quickly assemble lights rather than diverting almost 70 percent of production costs on logistics from overseas.

Activity Description

Liter of Light volunteers teach marginalized communities how to use recycled plastic bottles and locally sourced materials to make solar lights for their homes, businesses and streets. The lights are built and assembled at about 1/3 of the cost of other products on the market. About 20% is retained as a livelihood. Training is given for the community to maintain and repair their own units. Liter of Light has installed more than 350,000 bottle lights in more than 15 countries and taught green skills to empower grassroots entrepreneurs at every stop. Liter of Light’s open source technology has been recognized by the UN and adopted for use in some UNHCR camps.
