GravityLight works by lifting a weight – in this case a simple weighted bag. As it descends it actuates a pulley system connected to an alternator that converts the mechanical energy (or kinetic energy) produced by the movement into electricity, thus powering the lamp. The device is very simple to use.Jul 3, 2018
How is the GravityLight generating light without electricity?
It was designed by the company Deciwatt for use in developing or third-world nations, as a replacement for kerosene lamps. It uses a bag filled with rocks or earth, attached to a cord, which slowly descends similar to the weight drive in a cuckoo clock. This action powers the light for up to twenty minutes.

How much is GravityLight?
With the proceeds from a second Indiegogo campaign, GravityLight is now setting up an assembly line in Kenya. The lamp will cost $20 and be distributed through door-to-door (Avon Lady-type) networks, farmer groups, and more traditional market stalls.Aug 24, 2015
Why did they stop making GravityLight?
In 2019 we stopped manufacturing GravityLight to focus on a new product called nowlight. Pull on the nowlight cord to generate electricity. A minute of pulling creates up to 2 hours of light!
How long does a GravityLight last?
It uses a bag filled with rocks or earth, attached to a cord, which slowly descends similar to the weight drive in a cuckoo clock. This action powers the light for up to twenty minutes.
