Female Lamp Cord
Cord sets are detachable from both the power supply and the electrical equipment, and consist of a flexible cord with electrical connectors at either end, one male, and one female.
One end of the cord set is attached to a molded electrical plug; the other is typically a molded electrical receptacle to prevent the possibility of having an exposed live prong or pin which would cause electric shock.
The female connector attaches to the piece of equipment or appliance while the male plug connects to the electrical receptacle or outlet.
Use the female cord to connect lamp to ballast.
