Abstract
Devices for changing a light bulb (e.g., a compact fluorescent lamp or CFL), especially for those installed in high places, are disclosed. The device has a cylindrical tubular structure with one end opening to accommodate a light bulb. In one embodiment, at least one flexible thin arm with one end shaped to form a hook is pivotably affixed to the tubular structure. In another embodiment, a shaped insert is disposed in the tubular structure to provide necessary friction force to hold the light bulb in place during the changing process. The present invention is suitable for changing various types of CFLs.
