How long do ballasts 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. The optimum economic life of a fluorescent lighting system with magnetic ballasts is usually about 15 years.
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.
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.
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 happens when a ballast fails?

IMPORTANT: Flickering fluorescent tubes can cause the ballast to overheat and fail prematurely!
Article first time published onDo all fluorescent lights have ballast?
All fluorescent bulbs require a ballast. All compact fluorescent (CFL) bulbs require a ballast, which is often integrated. All HID bulbs require a ballast, which is sometimes integrated. No LED bulbs require a ballast, although some are engineered to work with an existing ballast.
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.
How do you know if a fluorescent ballast is bad?
- Flickering. …
- Buzzing. …
- Delayed start. …
- Low output. …
- Inconsistent lighting levels. …
- Switch to an electronic ballast, keep lamp. …
- Switch to an electronic ballast, switch to a T8 fluorescent.
How do I know if my fluorescent tubes are bad?
- Check the ends of the tube. If they appear darkened this indicates the bulb is burned out.
- Rotate the tube in the fixture if the bulb is not darkened on either end.
- Remove the bulb from the fixture if the bulb is still not illuminating.
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 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.
Why is my fluorescent light orange?
In a neon tube, ions are excited and then glow as their energy is given off in the form of orange coloured light. In the fluorescent tube it is a ultra-violet light that is given off, as the ions of mercury get excited then give off their light as the ions release their energy.
What does a ballast smell like?
A common source of these odors is the fluorescent light ballast. When called to such an incident, you typically will find an electrical odor or a haze of smoke.
Can a ballast explode?

In fact, fluorescent bulbs don’t lose any “life” when left on for up to three hours. … Fluorescent lights are generally rated to last about 20,000 hours when run for three hours at a time.
What is the difference between a ballast and a driver?
Fluorescent ballasts provide an initial spike of high voltage, generating an arc that travels from cathode to anode within the discharge tube. … LED drivers convert high voltage, ac current into the low voltage, direct current that LEDs are designed to run on.
Are fluorescent tubes being phased out?
The sale of halogen lightbulbs will be banned in the UK from September as part of ministerial efforts to cut carbon emissions. A ban on fluorescent lighting, which is mostly used in offices, will follow in September 2023.
Is it cheaper to leave fluorescent lights on?
“Turning off fluorescent lights for more than five seconds will save more energy than will be consumed in turning them back on again,” the DOE explains. … In light of these considerations, the DOE proposes a simple rule of thumb: Leave your fluorescent light bulb on if you will be out of the room for 15 minutes or less.
Is it cheaper to leave fluorescent lights on all the time?
It takes more energy to start a fluorescent that it does to run it, so leave the lights on all the time to save money on your electric bill. When you turn on a fluorescent light bulb (correctly called a “lamp”), there is a very brief jump in current when the ballast charges the cathodes and causes the lamp to start.
