As my bulb doesn't seem to fit any of the possibilities you put forward, TopSecret, I am forced to the conclusion that it was deceiving me and that I have been tricked into returning it.
BD, when I saw the term "hand-blown" it sounded like a contradiction until I remembered I was reading about a light bulb, and I did have to remind myself again when it mentioned where it was "hung".
From what I have heard of Hairball, he was a very reliable blogger. Although some forms of reliability are valued more highly than others, and I sense that your preference would be for one of the others. I also suspect that Hairball liked your blogs more than you liked his.
I know all too well from experience that no light bulb lasts 15 years, no matter what type it is. I knew it would die prematurely, so I stapled the receipt to the packaging and put it in a drawer; showing great foresight, I thought.
I do know how annoying a barking dog is, flyme, and if there had been an alternative to leaving it on its own I would have done it. My preferred solution would have been to send the dog out to work while I stayed at home.
He empties it on Sundays, Bn, and only into a plastic receptacle. If you were to get a plastic receptacle, you could empty into it as often as you liked.
Although my neighbour does look capable of murder, fortunately for me, a barking dog must not be enough to provoke him into it. Although, had the situation continued, who knows?
Although I have little affection for my upstairs neighbour, I could totally see his point; constant dog barking is very annoying. I'm just glad he didn't complain earlier, because there is absolutely nothing I could have done about it.
