I've encountered a couple CFLs that suffered catastrophic failures. I'm not sure but I suspect the electronics caught fire inside the base. The PCBs had some pretty nasty charring. The smell was absolutely horrendous. Both were Lights of America floodlights. After the second one burned up we decided to recycle the rest of that batch rather than take any more chances. I definitely won't buy another Lights of America product. Their quality is just garbage. The sad thing is those bulbs weren't at all cheap either.
