Product description Brand name and product description

GravityLight is a gravity-powered lamp designed by 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 thirty minutes. With neither batteries nor need for the sun, the lamp provides light instantly, can be stored indefinitely and used in many different environments.

There are currently two models of GravityLight produced and supported by Deciwatt, the GL01 and GL02.
