Check your lamps and light fixtures. Half a million LED bulbs are being recalled because they might catch fire.
There are several cases of smoke or fire coming from them.
They are 6, 8 and 9 watt (equivalent to 40 or 50 watts) LED bulbs made by Lighting Science Group, but you may have purchased them under the brand names Definity, Eco-smart, Sylvania or Westinghouse.
Remove the bulbs immediately. The manufacturer will send you a replacement.
Note: The bulb shown above is only one style of recalled bulb, yours may look different.
The Consumer Product Safety Commission has all the details: LED light bulbs recalled due to fire hazard.
