Difference between Electronic Ballast and Magnetic Ballast: Electronic ballasts change the frequency of the current without any change in the voltage. Magnetic ballasts work at a frequency of around 60 Hz The hertz (symbol Hz) is the unit of frequency in the International System of Units (SI) and is defined as one cycle per second. It is named for Heinrich Rudolf Hertz, the first person to provide conclusive proof of the existence of electromagnetic waves.Hertz
- If you can see some strong dark strips flickering in your camera, it must be a magnetic ballast based light.
- Otherwise it should be an electronic ballast based light.
How do I know if my camera has a magnetic ballast?
If you can see some strong dark strips flickering in your camera, it must be a magnetic ballast based light. Otherwise it should be an electronic ballast based light. The ideal distance between the light and the camera is less than two metres.
What is the difference between magnetic and electronic ballasts?
Magnetic ballasts work at a frequency of around 60 Hz, whereas electronic ballasts work at an increased frequency of around 20,000 Hz. This is why fluorescent lamps using electronic ballasts do not flicker or emit any buzzing sounds.
What is the function of electronic ballast?
Electronic Ballasts. Electronic ballasts alter the flow of electricity in the light bulb by using a series of induction coils that are separated from one another. They also change the frequency of the electrical current without changing the voltage. While magnetic ballasts in fluorescent lamps work at a frequency of 60hz,...
Where is the ballast on a light bulb?
These ballasts can be located inside your light sockets between the plug for the light bulb and the power chord. In magnetic ballasts, current flows through coils of copper wire before moving on to the light bulb.
How do I know if my ballast is magnetic or electronic?
Simply turn the light on, then take a photo of the fixture using your smartphone or digital camera. If there are no dark bands on the resulting image, you have an electronic ballast that will work with direct drop-in LED tubes.
What is the difference between a magnetic ballast and an electronic ballast?
Magnetic ballasts work at a frequency of around 60 Hz, whereas electronic ballasts work at an increased frequency of around 20,000 Hz. This is why fluorescent lamps using electronic ballasts do not flicker or emit any buzzing sounds. Electronic ballasts are also quite smaller in size and weight.
Can you mix magnetic and electronic ballasts?
There is no problem with replacing the magnetic ballasts with electronic ballasts, one at a time, light fixture by fixture, just keep track of the type of lamps that are specified on the label of the new electronic ballasts which will most likely be the T8 type lamps.
Can I replace a magnetic ballast with an electronic one?
Fortunately, compatibility isn't really an issue, as most electronic ballasts have been designed to replace existing magnetic ballasts. A preferable electronic ballast is the T8 model. This option has several advantages over the T10 and T12, including improved lighting efficiency.
How do I know what ballast I need?
When purchasing a ballast, you'll need to read the type of lamps it's designed for, how many lamps it operates, and the voltage the lamps will run on. Choosing the right ballast for a lamp will optimize the light output and life of the bulb.
Will LED tubes work with magnetic ballast?
These LED tubes are the newest, easiest to install and most expensive. They work with any kind of existing technology – whether it is T12 (Magnetic Ballast) or T8 (Electronic Ballast). To install them all you need to do is take the old fluorescent tube out and install the LED tube in its place.
What happens if you wire a ballast wrong?
If a ballast fails, it can cause a short, burn out tubes or even cause a fire, so it must be replaced. Lights that don't turn on, fluorescent tubes blackened near their ends, and brown, burnt tube electrodes are all indicators that a ballast is bad.
Does a magnetic ballast need a starter?
No Starters Required Magnetic ballasts required a starter to get the lamp lit, electronic ballasts do not require a starter.
How do I know if my ballast is T8 or T12?
If no markings are available, the size in diameter of the tube is the easiest way to determine the type you have installed. T8 tubes are 1-inch in diameter and T12 tubes are 1 1/2 -inch.
How do you test a magnetic ballast?

Why are magnetic ballasts being replaced?
Magnetic Ballasts or Electromagnetic (EM ballasts) fluorescent ballasts are rapidly being replaced by electronic ballasts for improved energy efficiency and function. New DOE requirements and long-term cost savings are driving the change.
Can I change a ballast without turning off power?
Although changing a ballast is safer with the power off, sometimes it is impractical, such as in a crowded store or office space, and you must replace the ballast without cutting the power. This can be done safely with some preparation and the right tools.
Where are magnetic ballasts located?
These ballasts can be located inside your light sockets between the plug for the light bulb and the power chord.
How does an electronic ballast work?
Electronic ballasts alter the flow of electricity in the light bulb by using a series of induction coils that are separated from one another. They also change the frequency of the electrical current without changing the voltage. While magnetic ballasts in fluorescent lamps work at a frequency of 60hz, electronic ballasts greatly increase that frequency to 20,000hz.
Is a magnetic ballast easy to operate?
Essentially, this contest has already been won. While magnetic ballasts are simple and easy in their design and operating principle, the more sophisticated electronic ballast just has too many advantages.
