The lamp holder has a body which houses a pair of electrical pin terminals. The body includes a pair of openings on one wall. The opening located at a position corresponds to the position of the electrical pin terminal such that each opening leads to one respective pin terminal. The lamp holder includes a pair of parallel spaced-apart electrical prongs of which one end of each electrical prong is in electrical communication with a pin terminal and the free end of each electrical prong protrudes from said body. The socket has a pair of spaced-apart electrical terminals, each having an opening capable of receiving one electrical prong of the lamp holder. The socket includes a pair of insertion holes for wire connection and includes a horizontal recess on the external walls for coupling to the luminaire.
