Abstract: FIELD: lighting engineering. SUBSTANCE: proposed starting-and-control gear characterized in functional integration of two ballast reactors incorporated in unitized electromagnetically active two-phase inductive module is used for fluorescent lighting fixtures having at least two gas-discharge lamps and two parallel ac power circuits for lamps. Connected in each of these circuits in parallel with lamps are ballast reactors each having winding and ferromagnetic core; in addition phase-shifting capacitor is connected in series with reactor in one of (any) circuits. Windings and cores of both ballast reactors are physically integrated into spatially coupled coils or coil groups wound with electrically insulated wire or ferromagnetic strip so that winding of one of reactors uses winding of other reactor as core, and vice versa. It will be good practice to wind mentioned coils or coil groups of unalloyed annealed low-carbon steel wire or strip. In some cases steel strip is reasonable to plate with aluminum or copper in the amount of 5 to 15% of strip width.
