Some fans come equipped with a light fixture to double as a central light. The fan is a hardwired fixtures so has to be installed electrically. Typically it is used with a wall switch or remote control. Ceiling fans can help keep you cool in summer and also warmer in winter by circulating the air.
A ceiling fan needs enough headroom, so is ideal over some furniture such as a couch, seating area or bed. See hugger fans for maximizing headroom. Fans are most often used in living rooms, family rooms and bedrooms, where people might be dwelling for a longer period of time.
