Gravity light / light

Gravity light

Because of infrastructure, two-thirds of people in sub-Saharan Africa have no access to electricity. At night, people's lives will be affected.
Therefore, we designed the "gravity power generation lamp", you can use any heavy objects (stones, bricks, a bottle of water) to generate electricity. And because of its own structure, you don't need to frequently remove the heavy objects and put them on again.
Combined with a low-power light bulb, it can provide a light source for dark nights.
