Deciwatt / Gravity Light

Deciwatt Ltd develops, manufactures and licenses off grid, clean energy solutions.
Deciwatt’s first product is GravityLight, an innovative device that generates light from gravity. It takes seconds to lift the weight that creates 25 minutes of light on its descent.
GravityLight offers a clean, safe, affordable and reliable alternative to kerosene and portable solar lamps. Uniquely, it has no batteries meaning it can be stored indefinitely, and works independently of the sun.
After a positive global field trial, GravityLight is in final development phase and will be in production in early 2015.
Deciwatt works with multilateral organisations, NGOs and government agencies to serve the emergency relief and aid markets, on a global scale.
Deciwatt will also work with retailers in high income countries to sell to ‘outdoors’ consumers as well as individuals preparing for natural disasters.
In all its work, Deciwatt strives to balance quality design with simplicity, reliability with affordability. Motivated by understanding and meeting consumer needs, Deciwatt will work with partners to develop and tailor the product range that best meets their needs.
