How to tell if fluorescent bulb or ballast is bad

Unlike incandescent and LED lights, fluorescent lighting requires a ballast that sends the correct amount of power into the bulb or tube. The ballast delivers enough voltage to start the lighting process.

Are your fluorescent bulbs on the fritz? Many large corporate lighting panels or office lamps operate with a little help from an electrical ballast. This device regulates the distribution of energy across your lighting fixture, working with a load to limit the amount of current in an electrical circuit. Eventually, when you flip the lights on, your bulbs will overload and fry! Here are a few signs that your ballast might need replacing:. This is a great place to start your troubleshooting journey.

Used primarily in fluorescent lighting systems, a ballast is an electrical device designed to regulate electrical current. It allows the light to turn on and then continually regulates the current flowing through the fluorescent bulbs, ensuring proper voltage and stable light output. Fluorescent tube lights would overheat and burn out very quickly without a ballast to ensure they do not draw too much electricity.

Unlike incandescent and LED lights, fluorescent lighting requires a ballast that sends the correct amount of power into the bulb or tube. The ballast delivers enough voltage to start the lighting process. Once the illumination begins, it backs off the electricity to produce a steady light. Without a ballast, fluorescent bulbs would use the V current and quickly burn out and ruin the product. If it goes bad, you'll see or hear symptoms that tell you it's time for a potential replacement. When a ballast starts failing, it will typically buzz or causes the bulbs to flicker. These issues can sometimes happen while it is operating as expected, so it's important to check the equipment before assuming a replacement is necessary. You'll need to safely turn off the fixture at the circuit breaker to check the ballast. Check to see if the voltage is still there any way for an extra layer of safety?
