The whole process of power generation GravityLight is such that the counterweight block is then obtained by above mentioned, power conversion to electric power. It will slowly decline, 30 minutes due to radiant energy, no electricity, the initial investment is almost zero, does not produce waste.

At the same time, the GravityLight can even to other devices for charging. You need to recharge the equipment can be connected to a GravityLight interface on the front panel. Even according to the different needs of users, to adjust the brightness of the GravityLight bulb, thus prolonging the service time.
