ABSTRACT:
A conductive sleeve is located around each of the filament supports of an incandescent lamp enclosed in a glass bulb. The sleeve is spaced from the support by an insulating spacer. The sleeve is connected to a ground so that if the bulb breaks liquid flowing into the bulb creates a conducting path between the filament supports and the ground. The sleeve has a generally hollow, cylindrical shape spaced and is positioned around the support.
