Glossary

Ceiling Fan Efficiency:

A weighted efficiency metric based on the ceiling fan performance at multiple speeds and in stand-by mode, expressed in cubic feet per minute per watt (CFM/W).

Ceiling Fan Light Kit (CFLK):

Equipment designed to provide light from a ceiling fan that is: (1) attached to the ceiling fan prior to the time of retail sale; or (2) not physically attached to the ceiling fan, but may be included inside the ceiling fan at the time of sale or sold separately for subsequent attachment to the fan.
