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

High pressure sodium lamp electronic ballasts power factor,that is a measure of electrical equipment inefficiency coefficient. The low power factor, the circuit for the alternating magnetic field converted reactive power, thereby reducing the equipment utilization, and increased loss of line-powered. Now many of the electronic ballast can reach more than 0.97. Electronic ballast power factor of JMS Series can reach more than 0.99, and its comprehensive energy-saving effect can reach 40%, "JMS series" or "James Lighting" a closer look.
