This is a Compact Fluorescent Light (CFL) bulb.

Dimensions: Length: 6.5 inches; Width (Diameter): 2.25 inches; Length socket base to top of ballast: 2.75 inches; Width (diameter) of socket: 1 inch.

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.
