Fluorescents are very flexible and fit in most standard incandescent sockets. With modern electronic ballasts, there is no more flickering or humming that was common with older ballasts. Some can even be used with dimmers.

Fluorescents are designed to last 10 times longer than incandescent bulbs. Operational savings reach 60%. Light quality is measured by the Color Rendition Index (CRI). Look for a CRI of 82 or higher when shopping for bulbs.
