Liter of Light is a global, grassroots movement committed to providing affordable, sustainable solar light to people with limited or no access to electricity. Through a network of partnerships around the world, volunteers teach marginalized communities how to use recycled plastic bottles and locally sourced materials to illuminate their homes, businesses and streets.


350,000 bottle lights in over 15 countries give light already

Liter of Light has installed more than 350,000 bottle lights in over 15 countries and taught green skills to empower grassroots entrepreneurs at every stop. The organization’s open source technology has been recognized by the UN and adopted for use in several UNHCR camps. The NGO is the proud recipient of the 2015 Zayed Future Energy Prize and a winner of the 2014-2015 World Habitat Award.


Sustainable source of light

The Liter of Light organization in Brazil also aims to provide an economically and ecologically sustainable source of light for homes and schools without resources or access to electricity. The light source consists of a plastic bottle filled with a solution of water and bleach, placed in small holes in the roofs of houses. The aim is to refract sunlight in order to illuminate the area beneath. The bottled light was created by Brazilian mechanic Alfredo Moser, who hung an improvised lamp in the roof of his home in 2002 during a blackout. And it was not long before his neighbors picked up on the idea.


Useful opportunity to help poor families

Philippine national Illac Diaz, creator of the MyShelter Foundation, which develops low-cost sustainable projects, saw the solution as an opportunity to help poor families in their country and was inspired by it to initiate the Liter of Light project. The idea has since been developed and applied in more than 20 countries on 4 continents, including Kenya, Colombia, Honduras and, most recently, Brazil.


Colombia wants to light up 100,000 homes in 2016

South America’s leading proponent Colombia aims to light up 100,000 homes this year. The MyShelter Foundation provided for the installation of 1 million bottles worldwide in 2015. The Liter of Light project commenced activities in South America in 2013 in Camboriú Municipality, installing its own team at headquarters located in the state capital Florianopolis.


Sika donation saves saving of 70% the final costs in Brazil

Sika Brazil has been supporting the NGO by gifting Sikaflex® and SikaBond® as well as providing financial aid. “It is essential to bring this partnership to Brazil as we can serve a greater number of people. The donation of sealants represents a saving of 70% on our final cost,” says Liter of Light president Vitor Belota Gomes.


Technical support and weatherproof products for installing the lights

“The challenge facing the NGO was to find a company offering the necessary high standard of technology and guarantee high-performance durable products that can withstand the weather conditions,” points out Sika Brazil’s Marketing Coordinator Rodrigo Silva. Sika Brazil also offers the complete gamut of technical support required for the application.

Besides Brazil, Sika supports projects in Bangladesh, Colombia, India, Mexico,
Nicaragua and the Philippines, among others. The project was also given public exposure at the World Resources Forum in Davos.
