A bi-directional switch that includes a first terminal, a second terminal, and a plurality of ballast circuits is provided. Each ballast circuit includes a first metal-oxide-semiconductor field-effect transistor (MOSFET) comprising a first input connector, a first output connector, a first body, and a first body diode, and a second MOSFET comprising a second input connector, a second output connector, a second body, and a second body diode. Each first input connector is coupled to the first terminal, each second input connector is coupled to the second terminal, and each first output connector is coupled only to the second output connector of the second MOSFET that is in a same ballast circuit.

A multiport AC link converter includes a resonant AC link, an input port, an output port, and a plurality of switches. A first subset of the switches is between the input port the resonant link and a second subset of the switches is between the resonant link and the output port. The switch sequencing for the input port is selected and executed independently of the switch sequencing for the output port the switch sequencings for the output port is selected and executed independently of that for the input port.

A system is presented including a tube light mounted in a tube light socket. The tube light includes a printed wiring board, one or more LEDs mounted to the printed wiring board, and one or more sensors mounted to the printed wiring board. The tube light also includes a power supply mounted to the printed wiring board, such that the power supply is connected to the tube light socket to supply a direct current voltage signal to the printed wiring board. A method is also provided for forming the tube light and mounting the tube light into the tube light socket.
