What Is a Light Ballast?


If you have ever owned a property with florescent lighting, no doubt you have in some way dealt with a ballast. Fluorescent lights are incredibly common, especially in homes and business buildings. A ballast is a tool that regulates the current in a circuit. For fluorescent lights, it regulates and limits the current running through the tube. Without a ballast, your florescent lighting would not be able to handle being connected to high voltage power. Your lamp would overheat and burn out in a second since the current would increase too quickly.

Our Marietta and Atlanta electricians explain more about light ballasts and how they are beneficial to you.

Is there a difference between residential and commercial ballasts?

Commercial lighting is typically more intense than residential lighting. Because of the intensity needed to light up large factories and warehouses, commercial lighting produces a stronger magnetic influence and more heat than the lamps you use at home. If you own a business and have florescent lights installed, it is essential to call a professional Atlanta electrician to handle it. Without the proper light ballast or installation procedure, you could have a fire hazard on your hands.

When should the ballast be replaced?

If you are experiencing flickering or humming coming from your fluorescent light, it could be a warning sign of an old ballast. The typical lifespan of a light ballast is 20 years, but poor light bulbs or cold air can cause the lifespan to reduce greatly.

When a ballast needs to be replaced, and you don’t know what you are doing, it is in your best interest to always call a professional. Electrical work can be incredibly hazardous and if you do not possess the proper training you could severely injure yourself.
