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

Magnetic choke is a type of fluorescent light that regulates the voltage of a fluorescent lamp by using a magnetic core. It works by using an electrical load to limit the flow of current especially when the load presents negative resistance.Magnetic choke can also be used to reduce the current in an ordinary positive circuit.

A Magnetic choke work by power supply, once the ignitor makes a plasma response in the gases in the fluorescent tube, the ballast purchases power that allows the plasma reaction to continue.Magnetic chokes were the first type of ballast and regularly have very low cycle charges that can effect in subtle flaming in the light.

fluorescent lamp ballast means a device which is used to start and operate fluorescent lamps by providing a starting voltage and current and by limiting the current during normal operation. The fluorescent lamp ballasts that are subject energy conservation standards include ballasts that operate.

Definitions for several of the covered ballast types are specified in the Code of Federal Regulations at 10 CFR 430.2.

Fluorescent lamp ballasts that are designed to operate at nominal input voltages of 120 or 277 volts; to operate with an input current frequency of 60 Hertz

James's ballast products represent many years of experience in ballast design and manufacturing. James offers magnetic chokes for all HID lighting sources including standard and pulse start metal halide lamps and high pressure sodium (HPS) lamps.
