Below is a picture of a CFL light bulb from my bathroom. I turned it on the other day and then smelled smoke after a few minutes. Four inch flames were spewing out of the side of the ballast like a blow torch! I immediately turned off the lights. But I'm sure it would have caused a fire if I was not right there. Imagine if the kids had left the lights on as usual when they were not in the room.
I took the bulb to the Fire Department today to report the incident. The Fireman wasn't at all surprised and said that it was not an uncommon occurrence. Apparently, sometimes when the bulb burns out there is a chance that the ballast can start a fire. He told me that the Fire Marshall had issued reports about the dangers of these bulbs.
Upon doing some Internet research, it seems that bulbs made by "Globe" in China seem to have the lion's share of problems. Lots of fires have been blamed on misuse of CFL bulbs, like using them in recessed lighting, pot lights, dimmers or in track lighting. Mine was not in any of those. It was a normal light socket.
I bought these at Wal-Mart. I will be removing all the Globe bulbs from my house. I have not decided yet if we are going back to incandescent bulbs at this point.

CFLs (compact fluorescent lamps) don't burn out the way incandescent light bulbs do. Instead, as they near the ends of their lives, they grow dimmer. While some CFL bulbs merely stop emitting light when they finally quit working, others kick the bucket with

National Geographic's Green Guide says of CFLs: "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
In a nutshell, healthy CFL bulbs may emit a bit of smoke and smell and have burnt-looking bases when they die, but that's as it should
However, flames shooting out the side of a bulb is not the way things should be. It needs be kept in mind that any electrical device can malfunction, either through manufacturing defects or as a result of misuse by consumers. Says Globe of the bulb in the photo, "As for this particular incident, the mention of flames/fire in the story is certainly outside of the norm and as such we would encourage the consumer to bring the bulb to their local fire marshal and/or safety authority to further investigate."
There have so far been no reported or confirmed cases of fire involving Globe-branded CFLs. In October 2010, however, the U.S. Consumer Product Safety Commission announced a recall of the Chinese-manufactured Trisonic brand of CFL bulbs due to "four reports of incidents, including two fires that resulted in minor property damage."
