Abstract

A light bulb changing device with expandable fingers is extendable to allow a person to install and remove light bulbs from an elevated ceiling without need for climbing a ladder. The device includes a tube, with the fingers attached thereto. A horn is slidably disposed on the top, movement of the horn adjusts the movement of the fingers. A compression spring and pulley housing with pulleys therein actuate movement of a tension member allowing for opening of the fingers and closing the fingers around a light bulb with limited torque to avoid breaking the light bulb.
