The device that provides the current for fluorescent lights Ballasts have become quite small, allowing the creation of compact fluorescent bulbs that can be used in place of incandescent bulbs Back to alphabetical list
A device for starting and regulating fluorescent and high intensity discharge lamps
Materials, solely carried to improve the trim and the stability of the vessel In vessels usually water is carried as ballast in tanks, specially designed for that purpose
An electrical device used in fluorescent fixtures to supply and regulate the necessary voltage and current to start and operate the lamp
device used for stabilizing current in an electric circuit (e.g.in a tube lamp supply circuit)
Any solid or liquid weight carried in a vessel to increase the draught, to improve trim or to regulate stability
any heavy material used to stabilize a ship or airship an electrical device for starting and regulating fluorescent and discharge lamps an attribute that tends to give stability in character and morals; something that steadies the mind or feelings coarse gravel laid to form a bed for streets and railroads make steady with a ballast
put into the hold to sink a vessel in the water to such a depth as to prevent capsizing
a device used with an electric-discharge lamp to obtain the necessary circuit conditions (voltage, current and wave form) for starting and operating; all fluorescent and HID light sources require a ballast for proper operation Dimming ballasts are special ballasts which when used together with a dimmer will vary the light output of a lamp
a circuit used to stabilize an electric current, for example, in a fluorescent light
is an electronic device that converts electrical current to the optimal voltage, current and waveform required to start and operate a fluorescent lamp
A device used with an electric-discharge lamp to obtain the necessary circuit conditions (voltage, current and wave form) for starting and operating
Device that transforms electrical energy used by fluorescent, mercury vapor, high and low pressure sodium, or metal halide lamps so the proper amount of power is provided to the lamp
The component of a fluorescent lighting system that regulates the electricity supplied to the lamps Most are housed in black metal cases about eight inches long
An electrical device used in fluorescent and HID fixtures It furnishes the necessary starting and operating characteristics to the lamp for proper performance
A device used in conjunction with an electric-discharge lamp to cause the lamp to start and operate under the proper circuit conditions of voltage, current, wave form, electrode heat, etc Electronic ballast: A ballast constructed using electronic circuitry Hybrid ballast: A ballast constructed using a combination of magnetic core and insulated wire winding and electronic circuitry Magnetic ballast: A ballast constructed with magnetic core and a winding of insulated wire
The electrical supply for some lights, such as fluorescents and metal halide bulbs These are available in several varieties, such as tar, transformer, and electronic They must be properly matched to the type of bulb you are using
A device that provides starting voltage and limits the current during normal operation for electrical discharge lamps such as fluorescent lamps Optimum Utility Systems can specify energy-efficient combinations of lamps and ballasts for new and retrofit applications in manufacturing office and plant environments See related article

Ballast is any substance that is used in ships or hot-air balloons to make them heavier and more stable. Ballast usually consists of water, sand, or iron
an attribute that tends to give stability in character and morals; something that steadies the mind or feelings
A transformer that steps down AC line voltage to voltage that can be used by fluorescent or other types of lighting Ballast's may be electromagnetic or electronic
Heavy material, such as iron, lead, or stone, placed low in the hold to lower the centre of gravity and improve stability
is equipment to control the operation of a fluorescent lamp from a specified low or high voltage AC or DC source (Typically between 12 and 240 volts) It can also include elements for starting the lamp and sometimes for power factor correction or radio interference suppression
A charging device in fluorescent lights which give a "jump start" to the gas inside the tube to make it start glowing steadily
