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

Electronic ballasts for metal halide lamps. Constituted by the housing and advanced electronic circuit technology. Mainly constituted by VMOS power switch-PWM dc / ac power converter has the PWM active phase correction / boost / voltage regulator circuit, PWM controller sweep trigger lighting circuit, self-powered circuit. To solve the the inductance ballast serious defects of the power factor of 0.99, less than 12% of the total current harmonic content, lumens coefficient of 0.97, saving 35% (with magnetic ballast ratio), volume small and lightweight.
