About this item
Product details
- The Joyous Light® is a crisp, bright white light ideal for reading and tasks that require visual accuracy
- CFL bulb has natural daylight balanced color temperature of 5500K
- Chases away winter blues, alleviates the effects of Seasonal Affective Disorder S.A.D.
- This is a large bulb that might not fit standard household lamps; see diagram above

Set of four (4) 27W compact fluorescent light bulbs, very bright at 5500K color temperature with 1300 Lumens output, 120V. 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 and renders colors of objects accurately for photography. They are also great as a task light or grow light bulbs. This is an energy-saving bulb with about 10,000 hours bulb life. Flicker-free, fits all medium-base E27/E26 sockets. Dimensions: Length: 6.5 inches; diameter: 2.5 inches; diameter of socket: 1 inch. Important: ALZO CFL bulb life is based on the bulb in an open-air upright orientation. When 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.
Is a photography light bulb different from a general use bulb?

extremely buzzy slash noisy
Not a Quiet lamp! I am measuring 8 decibels of BUZZ / HUM when these lamps are turned on! They might be bright but wow are they loud. They can be heard buzzing at 12 feet. Should be used in a stairwell only.
