GravityLight GL02

GravityLight is a lamp that is designed to hang from suitable fixtures in a house or dwelling. It uses a bag that can be filled with heavy items and winched up. As the bag descends it drives a generator through a gearbox which provides direct electrical power for a single LED. Additional SatLight lamps can be connected to the main GravityLight unit to extend lighting. Multiple Satlights can be linked together (recommended max of 4).
