A lamp ballast provides transformer to equalize the voltage amounts in fluorescent lighting. Filaments at the end of the lamp call for a low voltage to show on the light, while a larger voltage that runs from end to terminate in the bulb must keep the lamp running. Purpose from these lamps have differing voltages, a ballast has to transform the voltages to the appropriate requirements. The ballast also suppresses today's and keeps the lamp from receiving a lot of voltage and failing. Fluorescent lamp Requirements a ballast can be used for a lamp with a couple bulbs. Lamps with four bulbs usually require two ballasts. Ballasts must match the lamp's wattage, length and diameter....

The best styles of floodlights are known as high intensity discharge lights. These lights contain either metal halide or high-pressure sodium within the lamps. These types of lamps produce much more heat than standard filaments. The high heat levels may create a fire hazard when used inside, so it's best only to use HID floodlights outside, where the ambient temperature of the air can cool the bulbs. HID lights use the same technology as high-intensity headlamps in some vehicles. Standard floodlights that use regular light sockets can be used in any light fixture inside your home. However, floodlights require a larger space for the elongated bulbs. This makes them useful in recessed lighting in kitchens, garages or anywhere where extra light is needed. Only standard floodlights should be used indoors. Refer to the warning information on the side of the floodlight box to see whether it is rated for indoor use. Indoor bulbs have been tested for fire safety.A ballast is essentially a voltage controller for arc-type discharge lamps. In other words, a ballast is required for any fluorescent or HID light fixture to work. A ballast's main purpose is to regulate voltage to the lamp for start up and operation. Normally, the lighting ballast provideshigher voltage during the lamp's start-up and then limit the electrical current during operation to stabilize the arc. If a lamp was directly connected to a constant voltage supply it would draw an increasing amount of current until either the power supply or the lamp itself failed. The ballast acts as an essential buffer between the power supply and the lamp. The primary burst of voltage to the lamp is called the strike. There are two types of ballasts available to horticulturists: magnetic and electronic (digital) ballasts....

Choosing the right high intensity discharge (HID) lighting equipment is a process that takes some consideration. Many variables make up a HID horticultural lighting system, from the type of lamp (bulb) to the wattage and voltage of the unit. With new technologies emerging there is also a big difference in the way our HID bulbs are being illuminated. Regardless of the technology, HID lighting units comprise of two imperative pieces of equipment: the lamp and the ballast. All arc-type lamps (florescents and HIDs) have the ability to illuminate due to their construction (two electrodes separated by a gas). An arc is the discharge that occurs when the gas contained within the lamp is ionized by an initial burst of voltage. This phenomenon is similar to the way lightning ionizes the atmosphere due to the significant potential difference in voltage from the ground to the storm clouds. Once the bulb is struck, the electrical charge excites the gas molecules inside the bulb causing them to discharge photon particles and, therefore, create light. All HID bulbs rely on this discharge of gas to create light but it is not an instantaneous process. HID bulbs will only produce 5% of their brightness at ignition. Most bulbs require a few minutes of operation before they reach their full light output potential.A ballast is essentially a voltage controller for arc-type discharge lamps. In other words, a ballast is required for any HID or florescent light fixture to work. A ballast main purpose is to regulate voltage to the lamp for start up and operation. Generally speaking, a ballast will provide higher voltage during the lamp?¡¥s start-up and then limit the electrical current during operation to stabilize the arc.

The ballast High pressure sodium(HPS) lamps and Metal halide (MH) lamps, as with all HID lamps, use a ballast to regulate circuit conditions ¨C voltage, current, and wave form ¨C for starting and operating the device.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 made, the ballast quickly decreases the voltage and regulates the electric current to generate a steady light output. A Core and Coil ballast has three primary functions:establish an electric arc across the lamps limit current across the lamp after starter compensate for variations in line voltage and be sure consistent lumen output...

An electronic choke is a device created to control the amount of current within an electrical circuit. A well-recognized and traditionally used example is amagnetic ballast applied to fluorescent lamps, to limit the electricity through the lamp, which would otherwise increase to damaging ranges because of the lamp's destructive resistance feature. Ballasts vary in design complexity. They may be as elementary as a series resistor or inductor, capacitors, or maybe a collaboration thereof or as complex as electronic chokesused with fluorescent tubes,metal halide lamp and high pressure sodium lamps....

JAMES carried out the American ballast verification and authorized the verification mark that will be affixed to the ballast，High Pressure Sodium and Pulse-Start Metal Halide Lamps High pressure sodium and modern metal halide lamps which include existing lamps, 150W and less, as well as the new generation of pulse-start metal halide lamps, 150W and greater, have no starting electrodes. In addition to an OCV of approximately two times the lamp voltage, these lamps utilize an “ignitor”to provide a high voltage starting pulse directly across the main electrodes. Once the lamp’s arc is established,the ignitor automatically stops delivering pulses, and the lamp comes up to full brightness on its own....
