Lamps can overheat, causing the adhesive inside the lamp socket to melt and migrate into the bulb area of the socket. The cooled glue can adhere to the light bulb base and make the bulb difficult to remove which can result in a broken light bulb, posing a risk of laceration to consumers. Melted flammable glue that migrates onto the electrical components of the lamp poses a risk of fire.
