Our original product GravityLight is a lamp that is designed to hang from suitable fixtures such as a wall or ceiling. It uses a bag that can be filled with heavy items, such as rocks or sand, and winched up. As the bag descends it drives a generator through a gearbox which provides direct electrical power for a single LED. Each GravityLight is sold with two additional SatLights that can be used to extend lighting to other areas.
Please note that at present we are only able to ship GravityLight to a limited number of EU countries. To purchase GravityLight in other countries, please make your purchase via Amazon.
