Hi .
After reading your posts, I could must to say that I do not agree with these "destructive" practices, unless they were for experimental purposes only, but anyone are free to kill his own bulbs for fun.
All the bulbs in my collection are too valuable for me, and I wouldn't to do with them these unpleasant things.
Al my bulbs (incandescent, high intensity discharge, fluorescent, etc.) came to me (and continues doing today) during years and years of searching, waiting, illusion and expense... too high expense! so, when I? get some strongly desired lamp, these becomes to me as a sort of mysterious and rare treasure, even if the lamp are the simplest and cheapest bulb I could purchase.
Furthermore, in 1983, when the voltage from the transformer at my zone and subsequently at home, was raised from 125 to 220 volts, "Uni?n Fenosa", the local electric distribution company, gave us all the lamps we needed to exchange the old bulbs for new ones at the new voltage. Then I didn't throw away anyone of that 125 volt. bulbs I removed from service, so, today all of them are higly regarded waiting for a serious catalogation, including taking pictures of each one of them, off and on, exactly at the same parameters as when they were at service, at 125v, 50 Hz, to be displayed at my new bulb collecting site that will be online very soon.
Please, don't take this as a criticism to your experiments, heeeeeee.
If you enjoy overruning your obsolete incandescent bulbs for fun, go ahead. But I never could do the same with my old and obsolete ones without a strong affliction.
Very good and nice pictures anyway!
Best regards,
