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

Series connection !
1 starter circuit Instant-On (neon put a little glow to the U-move the contacts to generate heat expansion elongation) circuit switched the starter stop playing tap-chip cooling contraction circuit disconnect.
2 fluorescent ballasts equivalent self-inductance coil (great self-inductance electromotive force direction, with the same direction as the original voltage both add up to form instant high voltage is applied to the tube ends
3 normal lamps magnetic ballast buck current limiting, fluorescent lights work properly
