First try switching a CFL bulb that’s intermittent with one that works in the same fixture. If the intermittent one is intermittent in this socket too, then take it back for replacement.
Why do my CFL bulbs burn out quickly?
CFLs are admittedly more finicky than incandescent bulbs. Some of the factors that can cause them to burn out early include vibrations, temperature, enclosures, use with incompatible dimmers, poor base contact with the fixture, and fluctuations in power.
Why does my light bulb keep turning off?
If the bulb flickers on and off, it usually means that the switch contacts are getting bad. Usually, you’ll be able to hear a sizzling or crackling sound if the switch contacts are bad. In this case, replace the switch. It also could be that the wire connections are loose.
Can I use a CFL bulb in any fixture?
Since the light fixture can accept up to 75 watts of power, you can use any light bulb with a rated wattage of 75 or less. While you can use a 75-watt equivalent CFL, if you want more light in this fixture you could also use a CFL that produces as much light as a 100-watt incandescent.
What is the problem with CFL bulbs?
Some of the disadvantages of compact fluorescent bulbs are that they are cold temperature sensitive, not recommended for enclosed fixtures, can have a higher initial cost than incandescent, have a longer warm up time, they may have limited color temperatures, do not dim nearly as smoothly, and dimming decreases the
How long does a CFL last?
about 8,000 hours
The average lifespan of CFLs is about 8,000 hours, compared to the 25,000-hour lifetime of LEDs.
Can a faulty wiring cause a light bulb to burn out?
Loose or Improperly Connected Fixtures or Wiring
Loose wiring in a light fixture or the junction box it’s connected to can cause the voltage going to the bulb to vary, which wears out bulbs quickly.
Why does my LED ceiling light turn off by itself?
It’s either your controller or your power supply, which is either failing or exceeding its wattage capacity. It’s most likely the power supply/transformer if it’s older than 3 to 5 years.
Why does my light turn off after a few seconds?
A bulb that stays on for a few seconds then switches off is likely overheating. While not extremely common, it’s also not too rare when you have recessed lights in the ceiling, especially if the fixtures were initially designed for other types of light bulbs that normally generate more heat.
How do I know if my light fixture is bad?
Touch the bulb at the bottom of the socket with the other lead. Record the reading. If it’s somewhere close to 120 volts, the fixture is good. If you get a reading of zero or one significantly less than 100 volts, the fixture is bad.
Are CFL bulbs obsolete?
Now CFLs, or compact fluorescent lamps, are slowly disappearing from stores. Home retailer IKEA stopped selling them in all its locations last year, and now manufacturer GE has penned a cheeky Dear John letter to the technology, saying it will stop making the bulbs in the United States.
Which is better CFL or LED?
LEDs are more efficient than even CFLs: A 16.5-watt LED bulb is equivalent to a 20-watt CFL and a 75-watt incandescent.
Which is Safer CFL or LED bulbs?
LEDs are extremely long-lasting, with lifespans up to 10 times the length of a CFL bulb. They’re also highly durable and run without any heat build up. There is no mercury inside, making them safer than CFLs in that regard, and they utilize less energy than a CFL.
Is it worth changing CFL to LED?
If your CFL bulbs are working, it’s usually not worth replacing them with LEDs immediately – LEDs are more efficient, but the savings aren’t huge. Only replace them now if your CFLs aren’t suited to the fitting or are damaging fabrics. Otherwise, wait until they’re burned out.
When Should CFL be replaced?
Even though CFLs were initially known for consuming less energy, they are still not as energy efficient as LEDs. LEDs also reduce the cost of replacement lamps and maintenance time and fees. CFLs last around 8,000 hours. LED equivalents can last up to 25,000 hours and beyond.
How do you test a CFL bulb?

Quote from Youtube video: This is picked up by a light meter located here the strip you can see in front is to prevent any direct light transmission into the sensor. The light meter is recalibrated.
How do you check a ballast in a fluorescent light fixture?
With your multimeter set to ohm, or “Xl1” if there are multiple ohms on your meter, insert one of the probes into the wire connector containing the white wires. Touch the other end to the remaining blue, red, and/or yellow wires attached to the ballast. Your multimeter won’t move if your ballast has gone bad.
How do I know if my fluorescent tubes are bad?
When bulbs age and have been used for a long time, brown spots will appear. If darkness begins to form at the ends of the tube, the bulb may be near its end. While they may still light, they are wearing out and will die soon.
How do you test a 4 pin CFL socket?
Test the socket by attaching the clip of the continuity tester to the hot screw terminal, the black wire lead. Then, touch the probe to the metal tab in the bottom of the socket. The tester should glow. If it doesn’t, the socket is faulty and needs to be replaced.
