I'd read about the problem with these bulbs more than six years ago, but you know how you think it will never happen to you?
We were sitting in the living room and heard a loud pop; I thought something had fallen in the kitchen. When I got up to look, there was a pungent electrical burn smell. After a bit of panic and prayer (trust me, this is a scary smell), we traced it to a burned bulb in a lamp. Although it's claimed that the noise and smell are normal, I am not convinced.
