Why does my fluorescent light not come on sometimes?
If a fluorescent tube neither lights nor flickers when switched on, first check to see that the fixture is plugged in and that no fuse has blown or circuit breaker has tripped. If this does not help, try wiggling the tube gently in its sockets by rocking it back and forth and from side to side.

Why don’t my fluorescent lights work when it’s humid?
Fluorescent bulbs use a hermetic seal, which means no humidity will penetrate the bulb itself. This seal is necessary to keep the toxic mercury vapor from leaking out into the environment. Humidity can cause corrosion of the metal fixtures on the ends of a fluorescent bulb, impeding its ability to transmit electricity.
Why do my fluorescent lights only work sometimes?
Bad switches can be intermittent. Turn off the switch and take the tubes back out and put them back in making sure they’re fully snapped in. It’s worth a try. Don’t go buy more, but if you have other new tubes try them.
Does Weather Affect fluorescent lights?
Temperature: fluorescent lamp starting and light output are affected by surrounding air temperature. Most ballasts will start standard lamps down to 50°F. Special electromagnetic ballasts for standard rapid start lamps will start lamps down to 0°F.
How can you tell if a fluorescent light ballast is bad?
If your fluorescent lighting is displaying any of the signs below, it could be a symptom of a bad ballast:
- 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.
What are the two common possible causes of all common faults in fluorescent lamp fixtures?
Common Faults and Treatment Methods of Fluorescent Lamp
| Type of Fault | Reasons of Fault |
|---|---|
| Fluorescent lamp blinking ON and OFF | Loose contacts. Wrong circuit connections. Low supply voltage Defective starter. Defective fluorescent tube. |
Why does my fluorescent light take so long to come on?
Some older lights may contain a module called a starter. This unit sends a surge of current to the tube when the light first turns on. Over time, the starter can wear down and ultimately take longer to do its job. Lights that take a long time to come on or flicker on and off without starting are common symptoms.
Why do fluorescent lights flicker when cold?
Flickering fluorescent lights can also be a result of temperature. If the air around the bulb is cold and circulating, the bulb won’t be able to generate enough heat to work properly. The internal temperature of a fluorescent bulb should be about 50 degrees Fahrenheit for it to work properly and optimally.
Do LED lights work well in cold weather?
Unlike traditional lighting, LEDs actually thrive in cold weather, and are just as efficient as they are in any other environmental conditions. This translates to more energy-efficient lighting, as LEDs require a lot less energy use that results in carbon emissions and higher electric bills.
How do you know if it’s the ballast or the bulb?
Take out your current bulbs and replace them with the new bulbs. If the bulbs fail to light up, then 9 out of 10 times the ballast is culprit. You could also try using a multimeter set to measure resistance.
How much does a new ballast cost?
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.
How do you check for a bad ballast?
Quote from the video:
Quote from Youtube video: Go ahead and hook it we'll test this front ballasts first here I've got all the wires kind of brought up so we can just test them right here go ahead and hook your black from your meter to the white
How long do fluorescent ballasts last?
12 to 15 years
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.
Is there a way to test a fluorescent ballast?
To measure it, set your digital multimeter to around a thousand ohms resistance setting. Connect the black leads to the white ground wire on your ballast. Afterward, test every other wire with the red lead. When you do this test, a good ballast will return an “open-loop” or max resistance.
Will LED bulbs work if ballast is bad?
Can LED lamps work off of existing ballasts? Yes, if they have an internal driver than can work off that ballast. Philips, for example, has designed a tube that is compatible with an existing electronic ballast.
Can you put an LED bulb in a fluorescent fixture?
You have fluorescent tube lights in your home or business already, and you’re wondering if you can pop LED tubes in these fixtures or if you’ll need to change out the fixtures for something designed for LED. Good news! You can use LED tubes in your existing fixtures!
How often does a ballast need to be replaced?
The ballast takes in electricity and then regulates current to the bulbs. 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.
