The device is simple: a transparent two-liter bottle is filled with water plus a little bleach to inhibit algal growth and fitted into a hole in a roof.

The device functions like a deck prism: during daytime the water inside the bottle refracts sunlight, delivering about as much light as a 40–60 watt incandescent bulb to the interior.

Within months, the organization expanded from one carpenter and one set of tools in one community in San Pedro, Laguna to 15,000 solar bottle bulb installations in twenty cities around the Philippines, and began to inspire local initiatives around the world.

[5] MyShelter Foundation also established a training center that conducts workshops with youth, business companies, and other groups who are interested in volunteering their time to build lights in their communities.

[6] The Solar Bottle Bulb, as it has also been called,[7] is installed in the roof of homes with the purpose of refracting sunlight in order to light up a room.

After being filled with water and a little bleach, the bottle is pushed through a steel sheet that serves as a metal lock to prevent it from slipping.

By 2013, Vitor Belota, coincidentally Alanna's neighbor, had the same impetus to bring Liter of Light to Brazil after learning about the project in Kenya.

Today, Litro de Luz Brasil is established as a non-profit organization and since then has directly impacted the lives of more than 20,000 Brazilians through more than 3,700 solutions, reaching more than 120 communities across the country.

The movement in Colombia was started by Camilo Herrera in a small town called Duitama in the Boyaca Department, approximately 200 kilometers from Bogota.

They also presented the idea of Liter of Light to several local NGO's in seminars and workshops to reach all the off-grid communities of the country.

A group of seven students from the French University in Egypt (UFE) have begun Liter of Light locally in the context of a social and environmental development project.

[citation needed] In November 2014, PepsiCo announced that they will implement Liter of Light in 3 villages in upper Egypt, with two partners : SunUtions Company for solar solutions and Masr ElKheir organization.

The NGO wants in Europe to make the new generation aware of the energy poverty reality and show that they can have, with a small activity, a huge social and environmental impact.

During International cooperation, Liter of Light France is underlining the main philosophies of the movement as technological innovation accessible to everybody, capacity building, and initiatives South-South.

[citation needed] Inspired by the project of Isang Litrong Liwanag, Liter of Light was introduced to the people of India by Pradeep Chanti.

Later, Mr. Ranjeet Gakhare, an alumnus of Indian Institute of Technology Bombay, Ms. Bhavana Poppoppu and Mr. Chaitanya Reddy from Cornell University joined Pradeep and expanded the concept all over India.

With the generous help of several NGOs and various organizations, awareness campaigns and workshops were conducted in various cities like Hyderabad, Mumbai, Chennai, Kolkata, Jalpaiguri, and Delhi.

Starting with the one bottle in Vikarabad, the team is not only installing several models in houses of the unprivileged, but also mentoring various other organizations, NGOs, student bodies and the people in need.

[31] In 2014 it was carried out by Desire Foundation, Bhubaneswar on the coruscating day of Diwali to celebrate the festival of light in a unique style with the underprivileged.

Therefore, empowering the partner organization is a major goal and includes holding bottle-building workshops on site and setting up an operational framework.

[38] According to both of the organizations' objectives, and considering the fact that more than 11% of the Pakistani population lives without access to the electricity, including 50,000 villages that are completely separate from the national grid,[39] it was decided to form a partnership in order to implement the Liter of Light project.

The Swiss NGO plans to continue sharing lessons learned and spreading the concept via a global platform as well as launching more pilots around the world.
