How do I know if a ballast is bad? If your fluorescent lighting is displaying any of the signs below, it could be a symptom of a bad ballast: Flickering. Delayed start. Low output. Inconsistent lighting levels. Switch to an electronic ballast, keep lamp. Switch to an electronic ballast, switch to a T8 fluorescent.

Can a ballast catch 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 if you use wrong ballast? If you use a wrong sized ballast the LRC will not be tuned so you are likely to not start the lamp at all. There is the possibility of burning out components pre-maturely also due to overcurrent and overvoltage conditions particularly if using a larger ballast on a smaller fixture.

How do you test a fluorescent ballast? Turn off the fluorescent fixture's circuit breaker inside the breaker panel. Remove the fluorescent bulbs from the fixture. Remove the ballast cover from the fixture, if the ballast is not already exposed. Set the multimeter to the ohm setting. Can dust on a light bulb burn?

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.

Whether the bulb is installed upside down or right side up also plays a part in determining if the bulb will burn out early or not. Always make sure you hold the base, not the bulb itself, when screwing the bulb into your fixture.

The rough service application is another cause of shorter CFL life. Which means some burn out sooner, and some later. One thing to keep in mind is that CFLs are not meant to be turned on and off frequently. They last about 7, on-off cycles — so start making those hatch marks on your wall.
