Abstract: A fluorescent lighting assembly for a cabinet or display case may be retrofitted to provide non-fluorescent lighting of the cabinet or display case by providing an existing fluorescent lighting system of the cabinet or display case having a socket for receiving a fluorescent lamp. The socket has electrical contacts for providing current to the fluorescent lamp and is powered by a power source. An LED lighting assembly is configured for engaging the socket when the fluorescent lamp is removed so that the LED lighting assembly is held in place by the socket. The LED lighting assembly includes a base configured for coupling to the existing socket of the fluorescent lighting system and an electrical connector for engaging the contacts of the socket.
