For optimum efficiency, you should replace your magnetic ballast every 2-3 years. Digital ballasts last much longer, and have a consistent output over their life. They only need replacing if they stop working, which can be 10+ years.

Why do magnetic ballasts fail?

Causes of Ballast Failure Premature ballast failure is often caused by the surrounding environment. … When it’s too hot or too cold, the ballast can burn or fail to start your lamps at all. Heat combined with prolonged condensation inside an electronic ballast can cause corrosion.

How do you tell if a ballast is going out?

How often does a ballast need to be replaced?

A typical ballast will generally last about 20 years, but cold environments and bad bulbs can decrease this lifespan significantly. You can get a new ballast at a hardware store or home center and install it in about 10 minutes.

Are digital ballast better than magnetic?

Magnetic ballasts are easily the cheaper option when first buying. However digital ballasts, although pricey to begin with, will run more efficiently, use less energy and in effect help to lower your electricity bills over time.

How long does a ballast last?

According to the Certified Ballast Manufacturers Association, the average magnetic ballast lasts about 75,000 hours, or 12 to 15 years with normal use.

How do you know if you have a magnetic ballast?

1. If you can see some strong dark strips flickering in your camera, it must be a magnetic ballast based light.
2. Otherwise it should be an electronic ballast based light.

Why are my fluorescent lights flickering?

If your fluorescent bulbs flicker, most likely the problem is with the bulb itself. If the bulb is very dark on either end, it may be defective and burned out. The best way to test the functionality of a bulb is to put it into a fixture you know works. … Flickering fluorescent lights can also be a result of temperature.

Will a bad ballast burn out bulbs?

The ballast itself can go bad, which causes lights to flicker or even appear to be burnt out, when in fact they aren’t. They require maintenance and energy to power, on top of the power used to light the fluorescent bulb. They are a large part of the equation when using fluorescent lamps.

Do I need an electrician to replace a ballast?

Yes. As a matter of fact, you do need a lock out tag out device in place for changing a ballast. … ‘An electrician is replacing the ballast on a fluorescent light.

Article first time published on

How much does it cost to replace a ballast?

A replacement ballast costs about $10-25 depending on capacity and brand. The bite is that an electrician trip charge (which includes 30 or 60 minutes work) is going to be $75-150 probably – for about 5 minutes work on each light fixture.

Can a bad ballast cause a fire?

As with any electrical situation where overheating is possible, a bad ballast can pose a fire danger. The overheated ballast could cause the plastic housing on the light itself to melt and, in the right conditions, flame up.

What are magnetic ballasts?

A magnetic ballast is a piece of lighting equipment often used in small and large growrooms. … Like all ballasts, a magnetic ballast regulates the voltage a fluorescent light receives so that the bulb doesn’t overheat and immediately explode.

What are the disadvantages of magnetic ballast?

Some disadvantages of the inductive ballast are: they are less efficient than capacitive ballasts, they cost more, they weigh more, and they take up more space. Magnetic ballasts are typically used in reactors using medium pressure (MP) lamps.

Can a magnetic ballast be replaced with an electronic ballast?

Newer electronic ballasts are far more energy-efficient, don’t require a starter and are not as affected by cold temperatures as the magnetic predecessors. If you have an older fixture, you can switch from a magnetic ballast to an electronic ballast in a few minutes with some basic hand tools.

Do magnetic ballasts cause RF interference?

They can be noisy, and some components degrade over time. But the traditional ballasts are cheap, reliable, and cause no interference whatsoever, because they work on the mains frequency: 50/60 Hz!

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.

What is the difference between magnetic ballast and electronic ballast?

A magnetic ballast uses coiled wire and creates magnetic fields to transform voltage. … An electronic ballast uses solid state components to transform voltage. It also changes the frequency of the power from 60 HZ to 20,000 HZ or higher depending on the ballast.

How much electricity does a magnetic ballast use?

They consume eight to 10 watts when operating with the lamp in the circuit. The ballast will consume about four watts when the lamps are removed although the ballast is still energized.

How do I dispose of magnetic ballast?

You may be able to dispose of a few intact ballasts containing PCBs the same as ordinary trash or at a household hazardous waste collection event or drop-off location sponsored by your county, city, or waste disposal district or company.

How can you tell if a light ballast is bad?

1. Flickering. …
2. Buzzing. …
3. Delayed start. …
4. Low output. …
5. Inconsistent lighting levels. …
6. Switch to an electronic ballast, keep lamp. …
7. Switch to an electronic ballast, switch to a T8 fluorescent.

Is ballast needed for LED tube?

No LED bulbs require a ballast, although some are engineered to work with an existing ballast. You will find ballast-compatible or “plug-and-play” LEDs that are designed to replace linear fluorescents, compact fluorescents, or HIDs.

Will LED tubes work with bad ballast?

The TL/DR is “Yes, if a ballast burns out, always upgrade to LEDs rather than replace the ballast.” Here’s why: In most cases it makes sense to replace a fluorescent fixture with an LED replacement even if only the lamp burns out.

How do you tell when a fluorescent bulb is burned out?

1. Check the ends of the tube. If they appear darkened this indicates the bulb is burned out.
2. Rotate the tube in the fixture if the bulb is not darkened on either end.
3. Remove the bulb from the fixture if the bulb is still not illuminating.

How long do fluorescent bulbs last?

Typical lamp life for a fluorescent bulb is about 20,000 hours, but this can degrade as a consequence of frequent switching (turning on and off). Burning life is extended if lamps remain on continuously for long periods of time.

What are the common problems of fluorescent lamp?

defective starters, defective bulbs or a defective ballast. IMPORTANT: Flickering fluorescent tubes can cause the ballast to overheat and fail prematurely! They can even cause a starter to burn out! Don’t wait too long to fix the problem or you may end up with a bigger repair!

Why do fluorescent lights not turn on sometimes?

The fluorescent tube won’t turn on No electrical power due to a tripped breaker or blown fuse. A dead or dying ballast. A dead starter. A dead bulb.

Can you repair a ballast?

While simply swapping burned out bulbs in an existing ballast is deemed “ballast repair” by many – and can offer advantages in longevity and energy savings – sometimes this simple “fix” is not enough.

Why does my fluorescent light take so long to turn on?

Most fluorescent light fixtures also have a component called a ballast, which controls the current through the fixture. If the ballast is malfunctioning, it too can cause the light to take a while to turn on. But ballasts are very expensive to replace and they malfunction far more seldom than tubes and starters.

What is the purpose of ballast?

ballast – A device required by electric-discharge light sources such as fluorescent or HID lamps to regulate voltage and current supplied to the lamp during start and throughout operation.

Can a ballast explode?

Overheated fluorescent lights can cause fires! Overheating of the ballast could result in the following: … Explosion of the ballast due to the generation of gases inside.
