Designs That Are Lighting The Way

Liter of Light is a remarkable global initiative focused on improving the quality of life of people living in disadvantaged areas around the world. Liter of Light takes its name from the litre bottles used to make the lights (‘liter’ is the US spelling).

Making use of sunlight

The project teaches people in these communities how to use recycled and locally sourced materials to light their homes, businesses and streets. Ordinary plastic bottles are transformed into sources of light, simply by using the sun’s rays during the day.


Message in a bottle

Liter of Light aims to reach every home and to educate people at the same time to help conserve energy by using alternative sources.

A basic knowledge of electronics is all it takes, with a high powered one-watt LED light able to light a 15-square meter room, creating enough light from the bottle to read a book. It’s such a simple yet effective way to encourage people to conserve energy while the sun is out – and at the same time, improve the quality of lives.

Helping communities

To date, Liter of Light has installed more than 350,000 bottle lights in more than 15 countries at the same time as empowering a grassroots movement of entrepreneurs to better their communities. This simple product is giving people the chance to work, socialise and learn at night in their own homes in an affordable way, opening the opportunity for a brighter future.

This is an example of the kind of human ingenuity that’s inspiring us at EnergyAustralia to Light the Way. Read more stories of human ingenuity.
