T185-B lamp is suitable for all the users who use old type sunlight lamp, and they only need to take down starter and change the T185-B lamp to use; and if ballasttube is used, just take off it.
Currently, The Company of America Feizhao semiconductor has outputted two new FAN7710 and FAN7711 electronic ballast for compact fluorescence lighting (CFL) and tube lighting (tl).
Role: at start ballast circuits, the flip-flop because of the co-ordination of the moment have a high-voltage, so that the discharge lamp to start. Line at work to play the role of limit tube current.
