A 24-inch fluorescent light fixture is a common type of light fixture that measures 24 inches in length and uses fluorescent light tubes rather than standard incandescent bulbs. These fixtures can be purchased in most home improvement and hardware stores.
Fluorescent lighting is commonly found in kitchens and offices to provide a large amount of light without the heat associated with traditional bulbs. Fluorescent fixtures can be wired into standard home wiring and use a ballast to prevent flickering and humming. Because of the lower power consumption of this type of lighting, fluorescent bulbs are considered more energy efficient than traditional lights.
