Pipe in Pipe intelligent electronic ballasts

Line Construction: LR09A, LR09B consisting of ballast and distribution in the tube ends. Pipe in Pipe luminaries
Circuit principle: 220V rectified by adding power factor correction circuit, driver circuit by IC built-in MOS
Line features: the inductive heating device with the transistor two large separate, lower temperature rise, IC formed within the MOS driver circuit, and a warm-start default
Line Advantage: line stability, one good, long life, lamp will not damage the ballast damage.
Line Disadvantages: high cost of IC chip can only do the maximum power of 18.5W.
