ALZO 45W Joyous Light Full Spectrum CFL Light Bulb 5500K, 2800 Lumens, 120V, Daylight White Light

Full spectrum light bulbs for daylight balanced lighting, energy saving, long-lasting at circa 8,000 hours with 2800 Lumens output; low energy consumption, good for photo studio lights, or starting plant growth. These are Compact Fluorescent Light (CFL) bulbs. Fits all medium-base E27/E26 sockets, but this is a large bulb that might create a fit problem with standard lamp harps of household light fixtures; a larger lamp harp is needed, see ALZO 10 inch harp. Dimensions: length: 7 inches; width (diameter): 3 inches; length socket base to top of ballast: 3 inches; width (diameter) of socket: 1 inch. 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.
