ALZO 27W Full Spectrum CFL Light Bulb 5500K, 1300 Lumens, 120V, Pack of 4, Daylight White Light Description
Case of 4 full spectrum 27 watt light bulbs that imitate daylight, are energy saving, and have a long life of circa 10,000 hours with 1300 lumens output, 120V; low energy consumption, good for starting plant growth. These are compact fluorescent light (CFL) bulbs that fit all medium-base E27/E26 sockets, but the large bulb size might create a fit problem with standard lamp harps of household light fixtures; a larger lamp harp is needed, see ALZO 9 inch lamp harp. Dimensions: Length: 6.5 inches; Width (Diameter): 2.5 inches; Length socket base to top of ballast: 2.75 inches; Width (diameter) of socket: 1 inch. Important: ALZO CFL bulb life is based on the bulb in an open air fixture with sufficient ventilation. 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.
