Dimensions: Length: 10.5 inches; Diameter: 3.9 inches; Length socket base to top of ballast: 4.5 inches; Diameter of socket: 1 inch. Important: ALZO CFL bulb life is based on the bulb in an open-air upright orientation. When 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.
