Designers from London, Jim, Reeves, and Martin Reddiford have developed a lighting solution for developing countries. The program is cheap, unlike traditional electrical outlets and expensive solar power. The LED GravityLight lamp doesn't need charging power, and it means no cost.

The GravityLight features several pulleys and a carefully designed power system to do the work, as well as a retro - style counterweight wheel, which uses gravity to generate electricity. The whole power generation process of GravityLight is such that the weight blocks are referred to the upper level and then converted to power by means of the power obtained. It can slow down, lift 30 minutes of light energy, and without electricity, initial investment is almost zero, and no garbage will be generated.

At the same time, this GravityLight can even charge other devices. Devices that need recharging can be connected to an interface of the GravityLight front panel. It can even adjust the brightness of the GravityLight bulb according to the different needs of the user, thus prolonging the use time.

It is reported that the cost of this GravityLight bulb is less than 5 U. S. dollars (about 31 yuan). There is no doubt that, once the GravityLight light bulb comes out formally, its low price and simple operation will surely attract many consumers.
