How Long Should an Electrical Ballast Last? | BL Solutions

If you are a business or property owner who relies on electrical ballasts to power your lighting system, it is essential to understand How Long should an Electrical Ballast last? and when they should be replaced. 

What Are Electrical Ballasts?

An electrical ballast is a device used to regulate the current in an electrical circuit. It does this by providing resistance to the flow of current, which helps control the amount of power delivered to the load. Ballasts are used in various applications, including fluorescent lighting, HID lighting, and LED lighting.

How Long Should an Electrical Ballast Last?

The lifespan of an electrical ballast depends on many factors, including the type of ballast, the quality of the ballast, the environment in which it is used, and the amount of use. However, you can expect an electrical ballast to last for anywhere from 15 to 20 years. There are a few things that you can do to extend the lifespan of your electrical ballast.

1. Inspect your ballast regularly for signs of wear or damage.

If you notice any cracks, corrosion, or other damage, it is time to replace the ballast. Ballasts are durable, but they can still be damaged by physical impacts or exposure to extreme temperatures.

Inspecting your ballast regularly will help you spot any damage before it becomes a severe problem.

2. Keep your ballast clean.

Dust and dirt can build up on the surface of the ballast, which can cause it to overheat. When this happens, the lifespan of the ballast is reduced. You can keep your ballast clean by using a soft brush or cloth to dust it off on a regular basis. Do not use harsh chemicals or abrasive cleaners, as these can damage the surface of the ballast.

3. Use the correct type of ballast for your application.

There are different types of ballasts available, and each one is designed for a specific type of lighting system. Using the wrong type of ballast can lead to premature failure.

Consult with a lighting professional to make sure that you are using the correct type of ballast for your needs.

4. Keep your ballast cool.

Ballasts generate heat when they are in use, and this can shorten their lifespan. You can help keep your ballast cool by ensuring that there is adequate ventilation around it.

If possible, mount the ballast on a wall or other surface that will allow air to circulate around it.  You should also avoid using your ballast in an enclosed space, as this can cause it to overheat.

5. Install it at a Proper Area

The area where you install your ballast can also affect its lifespan. If possible, install the ballast in a cool, dry area. Avoid installing it in an area that is exposed to direct sunlight or excessive heat.

You should also avoid installing the ballast near any sources of vibration, as this can cause it to fail prematurely.

When Should You Replace an Electrical Ballast?

There are a few factors that can contribute to a shorter lifespan, such as:

  • Frequent power surges
  • Excessive vibration
  • Poor ventilation
  • Overheating

If you notice any of these issues with your ballast, it’s best to replace it as soon as possible. Ignoring these problems can lead to even bigger issues, such as an electrical fire.

If your ballast is over 15 years old, it’s also a good idea to replace it, even if you’re not experiencing any of the above issues.

Replacing an electrical ballast is a fairly simple and inexpensive process, so there’s no need to wait until it fails completely before taking action. You can avoid any potential hazards and keep your home or office safe by being proactive.

How To Replace an Electrical Ballast?

Replacing an electrical ballast can be done without too much hassle by anyone. However, if you’re not comfortable doing it yourself, you can always hire an electrician to do it for you.

Here’s a quick overview of the steps involved in replacing an electrical ballast:

Step 1: Turn off the power to the affected circuit at your home’s breaker box.

Step 2: Remove ballast cover. You may need to cut away any wires that are attached to it.

Step 3: Unscrew the ballast from the light fixture’s housing. You may need to cut any wires that are attached to it.

Step 4: Install the new ballast in the housing and screw it in place.

Step 5: Reconnect all the wires following the wiring diagram on the ballast. (not all ballasts are wired the same way)

Step 6: Turn on the power to the circuit at your home’s breaker box.

Step 7: Test the new ballast to make sure it’s working properly.

Just be sure to follow the steps carefully and always turn off the power before you begin working. With a little bit of time and effort, you can have your new ballast up and running in no time.

Benefits of Replacing Electrical Ballast

There are many benefits to replacing an electrical ballast, such as:

Compatibility: A new ballast is more likely to be compatible with LED replacement Tubes. Allowing you to save on Power.

Improved safety – by ensuring that your ballast is in good working condition, you can help prevent any potential hazards.

Extended lifespan – a new ballast will last longer than an old one that’s not been properly maintained.

Better performance – a new ballast will provide better performance than an old one that’s not been properly maintained.


An electrical ballast is a vital component of any lighting system. It helps to regulate the flow of electricity and prevents your bulbs from burning out too quickly. Most ballasts will last around 15-20 years, but a few factors can contribute to a shorter lifespan. If you notice any problems with your ballast, it’s best to replace it as soon as possible. It is a simple process that most people can do on their own. Just be sure to follow the steps carefully.
