Product Review

Set of four (4) 27 watt fluorescent light bulbs, super bright with 5500K color temperature and 1300 Lumens output, 120V, and a CRI of 91. The daylight balanced color temperature renders colors accurately for photography. This is an energy-saving bulb with about 10,000 hours bulb life. Fits all medium-base E27/E26 sockets. Dimensions: Length: 6.5 inches; width (diameter): 2 1/4 inches; length socket base to top of ballast: 2 3/4 inches; diameter of socket: 1 inch. 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. ALZO warranty for all CFL bulbs is 30 days.
