15 watt fluorescent light bulb, bright white, daylight 5500K color temperature and 750 Lumens output. The Joyous Light® bulbs are daylight balanced, i.e., their brightness is equal or very close to daylight. Customers praise the bulb's brightness that makes reading texts easy on the eyes; they are also used as a task light or grow light bulbs. This is an energy-saving bulb with about 10,000 hours bulb life. Fits all medium-base E27/E26 sockets. Dimensions: Length: 5 inches; Diameter: 1.5 inches. Pack of 4. Important: 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.

Love these lights !


even if you don't have SAD(season affective disorder) these bright lights lift your spirit


I purchased these to replace LED lights in the kitchen which were regularly interfering with the HD cable tv signal. I had purchased ALZO CFL bulbs several years before for the garage and really like the daylight quality of the light! These are perfect, they fit inside the globe fixtures and they do not interfere with the tv signal. LOVE them!!
