The detecting unit detects impedances between the pins of the lamp tube to determine the type of the lamp tube. The control unit is connected to the detecting unit, and operated to have some of the switches to turn one and the others to turn off whereby a drive circuit is formed enabling power from the power supply to flow through the lamp tube to make the lamp tube to generate light.
