Alzo Digital 45W 120V Joyous Light Full Spectrum CFL Light Bulb, 5500K,Pack of 4

Case of 4 Full Spectrum 45W light bulbs for daylight balanced lighting, energy saving, long-lasting at circa 8,000 hours bulb life with 2800 Lumens output, 120V; low energy consumption, good as photo studio lights or for starting plant growth. These are Compact Fluorescent Light (CFL) bulbs that fit all medium-base E27/E26 sockets, but their large size might create a fit problem with standard lamp harps of household light fixtures; a larger lamp harp is needed. 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.
