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

Magnetic fluorescent ballast VS electronic ballast
Low power factor (usually around 0.5) high (above 0.7, with a correction circuit can reach more than 0.9)
Energy loss is large (typically about 20% loss of power) is very small (saving 15 - 20%)
Low-voltage start-up performance is poor (less than difficult to start 180v) good (150v still normal start)
50Hz flicker strobe effect can not be overcome, for the sight of unfavorable operating frequency 20KHz or more, so no flicker feeling.
There 50Hz hum audible noise-free
Volume size
Light heavy weight (only inductive 2/10 weight)
High-frequency radiation is very small large
Cheaper expensive
Simple and more complex manufacturing processes
Fluorescent electronic ballast circuit designs are varied, scientific advances in today's electronic ballast design is moving towards integrated or modular, purpose is to make a simple circuit structure. Electrical performance is more reliable, stable and secure.
