This Light Bulb Solar Light is extremely efficient in making its own electricity to light itself. A self-sustaining light bulb that does not rely on external power. Instead, its built-in solar panels collect energy from direct sunlight. Amazingly, this is a 7W light bulb, enough to light-up a small room! Conveniently designed with a hook lid for hanging which is also removable if you wish to connect the bulb to a bulb socket.
