Provides an alternative lighting system to rural and peri-urban areas not connected to a conventional electricity distribution grid.
2013 SEED Low Carbon Award Winner Clean Energy Duitama, Colombia

Litre of Light light bulbs are an alternative method of lighting which does not generate heat, requires no maintenance, does not incur monthly costs and is self-sustaining. The materials required for production can be found everywhere: a discarded PET bottle, water, bleach and glue. The enterprise operates in over twelve cities in Columbia and is being replicated in five Latin American countries. A manual for making the light bulbs helps rapid dissemination. The project is sponsored by private enterprises.
