The Components Inside Each Ballast
This helps to regulate the initial electricity current given. Digital ballasts, on the other hand, are a newer technology, instead use electronic circuitry to regulate the amount of charge given, bringing more efficiency with little heat.
What is a digital ballast?
A digital ballast, which is similar to the microprocessor found in a home computer, controls the current and voltage going to the lamp using switching electronics and tiny frequency inductors.
What is the difference between electromagnetic ballast and electronic ballast?
Electronic ballasts operate at a higher frequency than magnetic ballasts—around 20,000 Hz—which is why fluorescent lamps using them dont flicker or make buzzing noises. Electronic ballasts are also considerably smaller in size and weight.
How do I know if I have an electronic ballast?
You can check if you have an electronic ballast that will work with direct drop-in LED tubes by simply turning on the light and taking a picture of the fixture with your smartphone or digital camera.
The majority of electronic ballasts have been created to replace existing magnetic ballasts, so compatibility is typically not a problem. A more preferable electronic ballast is the T8 model, which has several advantages over the T10 and T12 models, including improved lighting efficiency.
What is electronic ballast for fluorescent lights?
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 controls the current to the lamps in a fluorescent lighting system and supplies enough voltage to start the lamps.
Do digital ballast use less electricity?
Benefits of a digital ballast include: less expensive to operate (uses less electricity), lighter and more compact, cooler, and quieter.

What are the advantages of electronic ballast?
The disadvantage is that power fluctuations may result in a failure, but this can be mitigated by adding a buffer capacitor. Operation of the ballasts produces heat. Electronic ballasts are more effective, more compact in size and weight, and also offer the ability for continuous power adjustment at different settings.
When did electronic ballasts come out?
Early to mid-1990s saw a rise in the use of electronic light ballasts, and ever since then, these fixtures have steadily increased their market share relative to metal light ballasts.
The Certified Ballast Manufacturers Association estimates that the optimum economic life of a fluorescent lighting system with magnetic ballasts is typically about 15 years, with an average magnetic ballast lasting about 75,000 hours, or 12 to 15 years with normal use.
The most energy-efficient ballasts are electronic, or high-frequency ballasts. On a typical fixture with two 4 foot 40 watt T-12 fluorescent lamps, the ballast consumes about 13 to 16 watts of electricity, making the total consumption of the two lamps plus the ballast is about 93 to 96 watts.
A 600-watt and a 1000-watt bulb have the same starting voltage specifications, so the ballast will be able to light the bulb.15 Sept 2008
Rapid start ballasts are typically wired in series so that if one lamp fails, the entire circuit stops working. Rapid start ballasts are designed with a separate set of windings that transmit lower voltages to the electrodes for a brief period before the lamp ignites—roughly 3.5 volts.
A typical magnetic ballast is depicted above, with two connecting plugs on its side to connect it to the fluorescent light and an aluminum casing with the specifications printed over it.
The magnetic ballast converts the input line voltage and current to the voltage and current needed to start and operate the fluorescent lamps using a magnetic transformer made of copper windings around a steel core. Capacitors are added to help with lamp starting and power factor correction.
Ballast, other than cargo, may be placed in a vehicle, frequently a ship or the gondola of a balloon or airship, to provide stability.
A simple definition of a ballast is the heart of a fluorescent light fixture sending energy (pumping blood through the lamp) through it. A ballast also regulates the amount of current that flows to the lamps once they are turned on.
