Fluorescent tubes must have ballast to work, not directly connected to the mains. Start fluorescent ballasts give the lamp startup voltage, lamp start voltage is very high, such as a 36W T8 lamp start voltage exceeds 800V mains only 220V impossible to start. Started, ballast a stable and lamp current, lamp terminal voltage will drop to about 100V, not limiting measures, the lamp once started, will certainly overcurrent if connected directly to the mains, or even cause the lamp explosion.
