Abstract: An LED lamp tube and driver circuit that is direct replacement for fluorescent tubes with or without ballasts, that works with standard AC high voltage current input, with high frequency pulse current input, or with lower voltage input. The tube is wired to receive the current that is input from any two electrode pins from among the pairs of pins at the ends of the tube, which house the driver circuitry. The input current is converted to DC through a rectifier circuit, is filtered of unwanted frequencies and voltage through a filter circuit, and is controlled with a step-down constant current circuit to drive an LED array within the tube.
