Good info Phantom. Reminds me of the warning on Chinese light bulbs that caught fire. Warrigal is correct, we take "current events" too much for granted.
I bought a couple of these light bulbs at our local flea market a while back. Hey, only a buck apiece. How could I go wrong? As we sat watching TV one night I smelled something hot. I found my way to the light fixture and was amazedto see the base of bulb was red hot. I unplugged the appliance and it was quite a while before I could unscrew bulb and dispose of the darn thing right away. Lesson learned.
