The Nanoleaf design has pentagon-shaped “leaves” with apertures to focus the light emitted by LED lights within. The design provides 360-degree illumination and brightens up the whole room using just a fraction of the energy used by a normal incandescent bulb. It also has a temperature sensor that protects the bulb from overheating. This helps you use it safely in a fully enclosed lighting device or lampshade, and makes the bulb more durable and long-lasting.
