Brilliant idea! Solar light: Sunshine Lamp makes full use of the sunlight. It is composed of a solar cell and an easy-to-fold lamp cover. The expanding and compressing cover allows the user to control the light intensity. It can be fitted into a hole in the wall or the roof. The external component contains solar panels that absorb and store energy. The internal component is the lamp shaft. Pulling it open provides light, and closing it switches it off.
