Why Is My Light Bulb Turning Black?

Posted on September 22nd, 2016 by Jupiter Tequesta

electrician palm beach gardens | Jupiter-Tequesta air conditioning, plumbing and electricIs your light bulb turning black? Don’t worry!  This is normal for compact fluorescent light bulbs (CFL) that are nearing the end of their lives. Light bulbs that are starting to turn brown or black are starting to burn out and need to be replaced.

This is a normal process for CFL bulbs. Although they may emit a bit of smoke and smell when they die, they are designed to do this. According to the National Geographic’s Green Guide:

“Bulbs burn out when the ballast overheats and an electronic component, the Voltage Dependent Resistor (VDR), opens up like a fuse in your home’s fuse box, shutting off the circuit and generating heat and possibly a small amount of smoke. This might sound dangerous, but the VDR is a cut-off switch that prevents any hazards.”

Despite popular belief, CFLs that are burning out are not a fire hazard. However, it should be noted that electrical devices can malfunction if they are not used properly. Make sure that you are using the right light bulbs for the fixtures in your home. If you notice that your bulbs are dying out quickly, they might be improperly connected to your lighting fixture or you may be using the wrong wattage. Make sure that you are using a light bulb that is the proper wattage for your fixture to avoid overheating.
