fluorescent lamp electronic ballast

Our company has developed one kind of low overtone fluorescent lamp electron ballast in September, 2008, its total harmonic content is 5% 8%, the power factor is 0.99. If selects these two parameters for the power factor ≥0.98, the harmonic content ≤10%, our product is only. What is happier is we are in the low cost situation, made the such good product. After tests its own loss ≤2 tile, is also in all electronic ballast is lowest. Its product service life ≥30000 hour.
