Lighting Ballast
A low ballast factor may save energy but will produce less light.
Lighting ballast. These ballasts are available in either instant start or programmed start ignition for extended lamp life in frequent switching applications such as those where occupancy sensors or motion detectors are being used. Once the arc is established the ballast quickly reduces the voltage and regulates the electric current to produce a steady light output. 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. The ballast factor of practical ballasts must be considered in lighting design.
Ballasts are available in a standard light output high light output and a low watt design with input voltages of 120 to 277 or 347. There are various lighting ballast types available on the market. The term lighting ballast can refer to any component of the circuit intended to limit the flow of current through the light from a single. The ballast briefly supplies high voltage to establish an arc between the two lamp electrodes.
For more information on how it works you can consult our complete lighting ballasts guide. Ge 2 bulb commercial electronic fluorescent light ballast. Different types of lighting ballasts available. All fluorescent light fixtures consist of at least lamp s lamp holders ballast and internal wiring.
With fluorescent lamps ballast factor can vary from the reference value of 1 0. A lighting ballast is a piece of equipment required to control the starting and operating voltages of electrical gas discharge lights. For more information on how it works you can consult our complete lighting ballasts guide. Once the arc is established the ballast quickly reduces the voltage and regulates the electric current to produce a steady light output.
What is a ballast. In a fluorescent lighting system the ballast regulates the current to the lamps and provides sufficient voltage to start the lamps. Lighting ballasts are devices needed by a range of lighting technologies including hid lamps and fluorescent lamps. The ballast is used to create the voltage and current necessary to start and illuminate the.
The two most common types are magnetic and electronic ballasts and they come in. Some older types have starters too. The ballast briefly supplies high voltage to establish an arc between the two lamp electrodes.
