Festoon lighting is lighting that is hung in festoon manner. It
gets its name from the decorating styles of the Greeks and Romans
cultures. A festoon is a decorative garland of vegetation and
ribbon usually hung above a door or a window like a bow and some
times called a swag. However, festoon lighting does not have to be
decorative in nature. In fact, the term is more often used when
referring to temporary lighting, hung in festoon style, on
construction project. Look up article 520.65 and 590 in the 2011
National Electrical Code.
