A lighting assembly includes an LED string affixed to a lamp support connected between first and second lighting sockets and includes an non-conductive coupling and a pair of conductive support segments. Each support segment is connected between the coupling a corresponding lighting socket, either directly or via an intervening endcap. The LED string includes an LED module and a pair of interconnects. The LED module includes one or more LEDs and power circuitry for coupling a supply voltage to the LEDs. The interconnect pair may include positive and negative interconnects. A fixed end of each interconnect is electrically and mechanically connected to a corresponding support segment. The first support segment is electrically coupled to a positive terminal of a voltage source and the second support segment is electrically coupled to a negative terminal of the voltage source, the interconnect pair conveys a supply voltage to each LED module.
