Liter of Light is an open source design for low-cost light tube that refracts sunlight to provide daytime interior lighting for dwellings with thin roofs. Daytime lighting is cheaper than using electric lights indoors during the day. The device is simple: a transparent two-liter bottle filled with water plus a bit of bleach to inhibit algal growth and be installed into a hole in the roof. The device functions like a deck prism: during the daytime the water in the bottle refracts sunlight, producing as much light as 40-60 watt incandescent bulbs to the inside. Properly installed solar bottles can last up to 5 years.

History
The use of plastic bottles in this way to provide indoor lighting from daylight was developed by Alfredo Moser of Brazil. Using technology as a social company was first launched in the Philippines by Illac Diaz under the My Shelter Foundation in April 2011. To help the idea grow sustainably, Diaz applies the business model of "local entrepreneurs" where bottled balls are assembled and installed by local residents, who can earn a small income for their work. Within months, a carpenter and a set of tools in a community in San Pedro, Laguna, expanded the organization to 15,000 solar bulb bottle installations in 20 cities and provinces across the Philippines, and began inspiring local initiatives around the world. MyShelter Foundation also established a training center that organizes workshops with youth, business firms, and other groups interested in volunteering their time to build lights in their communities.
In less than a year since its inception, more than 200,000 bottle balls were installed in various communities around the world. The Liter of Light aims to illuminate 1 million homes by the end of 2015.
About the MyShelter Foundation
The MyShelter Foundation was founded by Illac Diaz in 2006 to create a system of sustainability and reliability through project building capabilities and job creation. Based on the concept of social enterprise, appropriate low-cost technology, and alternative construction in the Philippines, the MyShelter Foundation has pioneered projects such as Pier One Seafarer Boarding, Design Competition Element (DAtE), and School Bottle Project.

Description of technology
The Solar Bottle Bulb, as it is also called, is mounted on the roof of the house in order to bias the sunlight to illuminate the room. The project innovation lies in the utilization of cheap, durable materials available to produce high quality natural lighting that allows the urban poor to have access to an affordable and environmentally friendly long-term alternative to electric light for daytime use.
Most of the plastic bottles used are 1.5 liter recycled bottles. Once filled with water and a little bleach, the bottle is pushed through a steel sheet that serves as a metal key to prevent it from slipping. It was then embedded into a corrugated iron roof. A small portion of the bottle is left outside while the rest stands out into the house. The sealant is placed around a hole made on the roof to make it weatherproof. The properties of water bias ensure that the light from the sun reaching the inside of the bottle becomes omni-directional that mimics the electric light bulb and emits the same amount of light as a 40-60 W incandescent bulb depending on the amount of solar insulation available. Adding bleach to water prevents it from turning green with algae and ensuring high quality light keeps clear water for longer periods of time. To facilitate the use of the present invention through an open source mechanism, a step-by-step guide on materials and installation is available online.
Lem
Using glue that is durable, anti-leak, and fill the space, which is not melted by the sun, is one of the main challenges for the solution. Many local groups experiment with different adhesives to find the best solution for cost and quality. It is commonly found that silicone-based or polyurethane glue works best. The inventor, Alfredo Moser, used polyester resin.

Bangladesh
Lights Foundation, a youth social enterprise founded by local community worker Shanjidul Alam Seban Shaan who works on a bottle lamp project in Chittagong. They made a local version of a bottle of light called 'Bottle Bati' which cost about 2-2.5 USD and lasted for 4-5 years. R & D department D they work on local versions of night light bottles that can illuminate remote areas such as Sundarbans, Cox's Bazar Kutubdia Upazila, Khagrachari District etc. Where electricity is not available adequately, it will cost less than 6 dollars to make and will last for 4-5 years. They aim to spread awareness about bottled light to remote areas by training local school students. Approximately 44.80% of Bangladesh's population does not have access to electricity, about 24% of the total population are slum dwellers where people use illegal electricity, millions of people live in hill areas, where electricity is not available adequately; The purpose of the Lights Foundation is to serve those people. Lights Foundation became the Liter of Light state partner by officially launching Liter of Light Bangladesh, and Shanjidul Alam Seban Shaan became Executive Director. Liter of Light Bangladesh began to spread ideas in New York and other states.

China
Liter of Light China was created by three passionate international students from China in 2016, and the first project in Rudong will be done in early summer, 2017.
Colombia
The movement in Colombia was started by Camilo Herrera in a small town called Duitama in Boyaca Department, about 200 kilometers from Bogota. After launching a pilot in Bogota in partnership with Liter of Light Switzerland in February 2012, the local Bogota organization was created. The first bottles in Bogota were installed in the Divino area of ​​NiÃÆ' Â ± o and La Colina of Ciudad BolÃÆ'va. Volunteers in Bogota are also working with Un Techo Para Mi Pais to identify the areas in need.
Dominican Republic
The Liter of Light begins in the Dominican Republic by German volunteer Nicolai Rapp in 2015 which then distributes this project with German and other local volunteers in over 7 provinces. They achieved the installation of bottles and sunlights in more than 250 homes with a global fundraiser. In the focus of their movement is a rural area without or with limited access to electricity. They also presented the Liter of Light idea to several local NGOs in seminars and workshops to reach all the off-grid communities in the country. More recently, their efforts have also focused on bringing the project to Haiti, where about 75% of the population must live without access to electricity.
Egypt
A group of seven students from the French University of Egypt (UFE) has started a local Liter of Light in the context of a social and environmental development project. In November 2014, PepsiCo announced that it would implement Liter of Light in three villages in upper Egypt, with two partners: SunUtions Company for solar power solutions and Masr ElKheir organization.
French
In 2015, the French Liter of Light was created. The French branch is developing an important relationship between pedagogical projects in Europe and international cooperation around the world. NGOs want in Europe to make a new generation aware of the reality of energy poverty and show that they can have, with little activity, enormous social and environmental impacts. NGOs want, too, to deliver a message to developing countries that new generations around the world care about World Citizenship. During international cooperation, the French Liter of Light underscores the main philosophy of the movement as a technological innovation that is accessible to everyone, capacity building, and South-South initiatives. The movement in France was started by Olivier Lasbouygues, Paola Sierra and Isabel Rico.
India
Inspired by Isang Litrong Liwanag project, Liter of Light was introduced to Indians by Pradeep Chanti. The first experiment was conducted in Vikarabad, a village in Telangana in 2011. The bulb was successfully installed and still functioning. With this experience, the team is gradually expanding its concept. Then, Mr. Ranjeet Gakhare, an alumnus of the Bombay Institute of Indian Technology and Chaitanya Reddy of Cornell University joined Pradeep and expanded the concept across India. With the help of many NGOs and organizations, awareness, campaigns and workshops are conducted in various cities like Hyderabad, Mumbai, Chennai, Kolkata, Jalpaiguri, Delhi, etc. Starting with a bottle in Vikarabad, the team not only installed some models in poor people's homes, but also mentoring other organizations, NGOs, student institutions and people in need. The Liter of Light demonstration was performed at TEDxChristUniversity in November 2012. In 2014 this was done by the Desire Foundation, Bhubaneswar on Diwali day to celebrate the light festival in a unique style with the less fortunate.
Liter of Light India was nominated for Change Maker's Award by Uttarakhand Sustainable Development Festival and for 'Young Achiever's Award' by prestigious society magazine.
Liter of Light India also took initiatives such as Women's Empowerment, Urban Hygiene and Education.
Kenya
A youth group called Koch Hope has started installing a 2L PET bottle in the slum area of ​​Korogocho. At first people were skeptical that the bottle installation would let the water in, so the first bottle was installed in the local school as a test. The locals then bought the idea and the first 100 lights were installed in April 2011 for free in the hope of attracting interest and donors. Furthermore, local initiatives want to expand to other areas around Nairobi.
Malaysia
Liter of Light Malaysia runs its first project in June 2015, and is run by a Malaysian-based social business called Incitement, founded by Zikry Kholil and Daniel de Gruijter, which runs several social initiatives. Liter of Light Malaysia has so far completed 36 projects, mainly for marginalized communities in Pahang, Malaysia and Indigenous communities living in Cameron Highlands, but also in Sabah and Sarawak in East Malaysia (Borneo). After the Incitement launched the Liter of Light Malaysia, it also pushed the Liter of Light into the Italian market under the Italian Incitement umbrella. To date, Liter of Light Malaysia has installed 1850 solar lights in rural Malaysia, effectively providing night light for more than 6,000 less capable Malaysians.
Mexico
The Liter of Light starts in Mexico in early 2013, sponsored by QohÃÆ'Â| © let A.C. Founded by Tere Gonzalez, who previously worked with Liter of Light in India & amp; Spain, the group started operations with a pilot program in the state of Chihuahua MÃÆ'Ã… © xico, where they could benefit 114 people. Until September 2013, they are working to complete the next installation phase in Ajusco, Mexico City, to benefit the 500 other families.
Nepal
(PROJECT UJYALO) "Ujyalo" means "light" in Nepali. Ujyalo is one of the initiatives started by the Ujyalo Foundation in Nepal.
Ujyalo created a lighting system using a used plastic bottle that reinforced a little sunlight with the help of water by netting it in different directions to light up the room. Ujyalo was inspired by the initiative "A Liter of Light".
The ball is aimed at creating an environmentally friendly, energy-efficient and cost-effective system that can be used to illuminate homes in Nepal that have no access to electricity or can not afford it. In addition, this will not only help provide light, but will also help us recycle the wasted plastic bottles from the community.
Furthermore, given that major cities in Nepal, such as Kathmandu, have to bear nearly 20 hours of winter load removal every day, the project has potential and needs in both rural and urban Nepal.
Dutch
The Dutch Liter of Light aims to realize projects in countries that are in line with the goal of establishing a local Liter of Light sub-organization and its work there are three. Prior to the project, the work focused primarily on information gathering, project preparation, promotion and fundraising. During projects abroad, the project focuses on spreading ideas and inspiring people to engage with the Liter of Light and even start their own projects. Therefore, empowering partner organizations is a key objective and includes organizing bottle-making workshops on site and preparing operational frameworks. After the project, the partner organization will be assisted and continuously supported by the Dutch Liter of Light.
Pakistan
Partnership has been made with Ace Welfare Foundation, Pakistan. According to both organizational goals, and consider the situation that more than 11% of Pakistan's population live without access to electricity where 70% of individuals live in rural areas in 50,000 villages completely separated from the national network, it has been decided together to form partnerships in order to implement project LITER OF LIGHT in the PAKISTAN area, under the representation of ACE WELFARE FOUNDATION, established by Mr Vaqas Attaullah Butt.
