Abstract

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.
