Why does a CFL stop working?

Why does a CFL stop working?

In a bulb that burns out early, the electronic components may have been inferior in quality or poorly installed, or the bulbs might have been physically damaged in some way during transport from China, where most are manufactured. The electrical components also complicate the end of life for the CFL.

How do I know if my CFL bulb is bad?

How to Tell If a Fluorescent Tube Is Bad?

1. Check the ends of the tube. If they appear darkened this indicates the bulb is burned out.
2. Rotate the tube in the fixture if the bulb is not darkened on either end.
3. Remove the bulb from the fixture if the bulb is still not illuminating.

Do CFL bulbs burn out?

CFL bulbs are cheap, long-lasting, and come in every color temperature, however, they tend to burn out before their typical 8,000 hour life.

How long can you leave a CFL on?

CFLs use about 75 percent less energy, plus each bulb can last up to 10,000 hours if used correctly. Super energy efficient CFLs, they use about 75 percent less energy than regular incandescent bulbs, and each bulb can last up to 10,000 hours if used correctly.

How many hours do CFL bulbs last?

The typical incandescent bulb lasts about 1,000 hours, while a 15-watt CFL bulb lasts 10,000 hours and a 12-watt LED bulb lasts 25,000 hours. In other words, incandescents last about a year while CFLs can last 10 years and LEDs up to 25.

How do you test a CFL bulb?

Set a multimeter to the ohm (Omega symbol) setting, then touch one tester probe to each of the pins at the end of the bulb. If the tester shows a reading between 0.5 and 1.2 ohms, the bulb has continuity.

What if I vacuumed up a broken CFL?

* If you already vacuumed a broken CFL: For a recent break (within a couple of days of the break): Air out the house for up to several hours to get rid of any remaining mercury vapor and change your vacuum cleaner bag or wipe out the dust cup.

How long do CFL bulbs last?

Do CFL bulbs dim over time?

Another reason you need more lumens is that a CFL will dim over time. It will lose 20 to 25 percent lumen power after 4,000 hours (40 percent of a CFL’s 10,000-hour-rated life). Incandescent bulbs also lose lumens, but the life of these bulbs is extremely short compared with that of CFLs.

Why is my fluorescent light not working properly?

Like other lighting fixtures, fluorescent light fixtures sometimes work improperly. Aside from a burnt tube, other factors, such as a worn starter and loose or oxidized electrical contacts, can contribute to a fluorescent light not working properly.

One clue that your ballast is the reason for a non-working fluorescent light is the light bulbs struggle to turn on. As I said in the intro, we noticed this happening over a 3-4 week period. A good way to check that your ballast is the culprit is to turn on a voltage detector and hold it next to the wires supplying power to the ballast.
