This is a compact fluorescent light (CFL) bulb. Fits all medium-base E27/E26 sockets, but its large size might create a fit problem with standard lamp harps of household light fixtures; a larger lamp harp is needed. Dimensions: Length: 7 inches; Width (Diameter): 3 inches; Length socket base to top of ballast: 3 inches; Width (diameter) of socket: 1 inch. Important: ALZO CFL bulb life is based on the bulb in an open-air upright orientation. When ALZO bulbs are installed in fixtures that lack adequate ventilation, the life of the bulb will be reduced. If an ALZO CFL bulb is installed in an overhead recessed light fixture with the bulb glass below the base, the life of the bulb will be greatly reduced.
