China manufacturer of magnetic ballasts for metal halide flood lights & hps flood lights

T8 Fluorescent lamp diameter, starter ignition voltage is low. Relative to 220V, 50Hz frequency alternating current, consistent starter ignition voltage is less than 1/2 power supply voltage law. magnetic ballast can be used for starter ignition operation. magnetic ballast as simple structure, long life, work together as a first fluorescent lamp ballasts, and its market share is still relatively large, however, because of its low power factor, low-voltage startup performance is poor, energy-heavy, strobe and many other shortcomings, its market slowly being replaced by electronic ballast,Fluorescentballast 40W energy loss: 40W (lamp power) +8 W (ballast own heat loss) equal to the total power consumption lighting package to 48W
