In November 2012 GravityLight was at risk of being shelved unless funding could be found to support a trial: the tooling, manufacture and distribution of at least 1000 gravity powered lights. The plan was to gift the lights in both Africa and India to use regularly and use their feedback to develop a more efficient second version for eventual high volume production.
However, the interest and global generosity towards GravityLight massively exceeded expectations - raising $399,560 vs the original target of $55,000. This overwhelming support enabled the team to further improve the design, pushing back the timing of the production run and trial to Autumn, as they focused on improving GravityLight's efficiency, robustness and quality of light.
