This remarkable product was developed for countries which lack widespread access to electricity. We are proud to have been chosen to sell it in the UK, as a reliable off-grid lighting solution.
GravityLight is designed to hang in a house or outbuilding, or temporarily outside from a tree or the side of a campervan. It uses a bag filled with 12kg of soil / sand / rocks or water bottles which is then effortlessly winched up. As the bag descends it drives a quiet generator through a gearbox which provides direct electrical power for the bright LED lights.
The pack includes 2 ‘SatLight lamps’ that can be connected to the main GravityLight unit to extend lighting. Each SatLight comes with a 5m cable, and they are connected in series to you can get light up to 10m from the GravityLight.
Operation is near-silent: a slight whirling hum from the mechanism. Obviously because the energy is stored in the weight, there are no batteries to replace – ever!
