A single core and coil ballast can be used when the input voltage to a fixture meets the starting and operating voltage requirements of an HID lamp. In this situation, the reactor ballast performs only the current-limiting functions since the voltage necessary to initiate the ignitor pulses, and start and sustain the lamp comes directly from the input voltage to the fixture. The reactor ballast is electrically in series with the lamp. There is no capacitor involved with the operation of the lamp. Because of that, the lamp current crest factor is desirably low, in the 1.4 to 1.5 range.
Without a capacitor, the reactor ballasts are inherently normal power factor devices (50%). Where necessary, to reduce the current draw during lamp operation, a capacitor may be utilized across the input line to provide high power factor (90%) operation, but the addition of the capacitor will not affect how the ballast operates the lamp.
Magnetic ballasts, capacitors are needed to improve (input) power factor. As a result, the number of lamps that can be operated on a circuit nearly doubles. In large installations, power factor correction is also required to avoid power quality problems and utility penalties. Capacitors are integral components of CWA and regulated lag circuits; they will not operate without capacitors. Both oil-filled (wet) and dry-film capacitor technologies are commonly used with ballasts. A means to discharge capacitors after power is turned off is a safety requirement.
both oil-filled and dry film capacitors for the HID and sign ballast lighting markets.Constructed with film designed to withstand the rigors of the application, these units are built to operate up to 105ºC.
HID lighting film capacitors are built with a ±3% tolerance on capacitance, and are designed to operate for a minimum of 60,000 hours. Sign ballast capacitors are constructed with film/foil technology and have tolerances based on application requirements....

Ballast Basics:
Fluorescent and HID lamps require a ballast to apply starting voltage to the lamp and establish current flow – an "arc" – between the lamp electrodes. Once the lamp is operating, the ballast also regulates lamp current and power. Ballast types fall into two broad categories:
Magnetic Ballasts
A simple device that uses a core and coil assembly transformer to perform the minimum functions required to start and operate a lamp. Magnetic ballasts are often found in HID systems, as well as older fluorescent systems.
Electronic ballasts use semi-conductor circuitry to regulate the current flowing through the lamp. The electronic components that compose an electronic ballast are smaller and lighter than the core and coil assembly of a magnetic ballast. Thus an electronic ballast can weigh less than half as much as a magnetic ballast of the same size.
Different lamps require specific ballasts designed to maintain current levels needed for varying tube designs. Using a mismatched lamp and ballast can shorten the life of all components and increase the possibility of overheating, failure and leakage....

Metal halide (MH) lamps, as with all HID lamps, use a ballast to regulate circuit conditions – voltage, current, and waveform – for starting and operating the device.The first lighting ballast technology used to operate MH lamps were electromagnetic, also known also as a “core and coil” ballast for bulky, heavy, magnetic core of laminated steel plates wrapped in copper windings.All lighting fixtures consist of at least lamp(s), porcelain lamp holder,core and coil ballast and internal wiring.
In a fluorescent lighting system, the ballast regulates the current to the lamps and provides sufficient voltage to start the lamps. Without a ballast to limit its current, a fluorescent lamp connected directly to a high voltage power source would rapidly and uncontrollably increase its current draw. Within a second the lamp would overheat and burn out. During lamp starting, the ballast must briefly supply high voltage to establish an arc between the two lamp electrodes. Once the arc is established, the ballast quickly reduces the voltage and regulates the electric current to produce a steady light output....

The first lighting ballast technology used to operate MH lamps were electromagnetic, also known also as a “core and coil” ballast for bulky, heavy, magnetic core of laminated steel plates wrapped in copper windings.A ballast is a device designed to regulate the voltage within an electrical circuit. This page addresses only ballasts used in circuits containing electric gas-discharge lamps. Examples of gas-discharge light sources include neon and fluorescent lights and high-intensity discharge (HID) lamps.
A single core and coil ballast can be used when the input voltage to a fixture meets the starting and operating voltage requirements of an HID lamp. In this situation, the reactor ballast performs only the current-limiting functions since the voltage necessary to initiate the ignitor pulses, and start and sustain the lamp comes directly from the input voltage to the fixture. The reactor ballast is electrically in series with the lamp. There is no capacitor involved with the operation of the lamp. Because of that, the lamp current crest factor is desirably low, in the 1.4 to 1.5 range.
Magnetic ballasts use a core and coil wrapped around a metal core, essentially an electromagnet, to generate an inductive field that affects the voltage flowing through the coil wire. Because they work at a lower cycle than electronic ballasts, you may notice a flicker or hear a hum coming from fixtures containing electromagnetic ballasts.
Without a capacitor, the reactor ballasts are inherently normal power factor devices (50%). Where necessary, to reduce the current draw during lamp operation, a capacitor may be utilized across the input line to provide high power factor (90%) operation, but the addition of the capacitor will not affect how the ballast operates the lamp.
Reactor ballasts limit the number of fixtures that can be used on a circuit because they draw substantially more current during lamp starting (warm-up) and/or open-circuit operation (burned-out or missing lamp), than when the lamp is operating normally....

LED High bay light fixtures are the economical choice due to their long life, low power consumption and low heat output. LED High bay lighting fixtures for lighting warehouses, industrial, and retail facilities. As a general guideline, divide your current Metal Halide (MH) or High Pressure Sodium (HPS) bulb's wattage by 3 or 4 for the comparable LED wattage.
As we all know, there are many advantages of the led high bay light such as energy-saving effect, long using life, no radiation, no stroboscopic effect, no noise, soft light, wide operating voltage and a series of good characteristics. Because of these good factors, the LED flood light has been increasingly welcomed by most of consumers. the working condition of the 400W metal halide replacement could also show the quality of the LED lamps. In the normal working condition, the temperature rising should be relatively low. On the other hand, if the conditions of heat dissipation are not good, the led light would become very weak at high temperatures. At the same time, if the led high bay light has rapid blinking in the lighting on and off, there would exist quality problem.
