The serious But why do I have to devalue this bulb:
I changed the old bulb from my bedside lamp against this model. The second dress I've scared me right now. Approximately after three seconds came a short flame (about 4 to 6 cm) and a noise as if something fizzle. The fuse was thrown out. After the initial shock, I unscrewed the bulb and looked (see uploaded images on the product page). In threaded hole could be seen on its side, the glass version was fouled. The hole as a defect was not recognizable as such when unpacking from the packaging, the greater was the surprise at this "spectacular" defect. Perhaps more should be noted is that the bedside light for many years now doing its job without a similar case would ever occurred.
Frankly, I am become somewhat cautious about addressing my two remaining bulbs of this type. I mean what would have happened if the lampshade catches fire? Admittedly, this is probably not very realistic because of the relatively short Verpuffungszeit - but I would like it not to test and take the chance anyway ...: - /
Until that time I had this pear given five stars, but the incident described above will work for me now pretty after it comes to safety ... I just hope that it's been an isolated incident.
Addendum 12.15.2014:
The two remaining lamps (bolted from skepticism "refractory" environment, eg no curtain or shade near) function to this day with no problems and absolutely reliable. It seems probably actually act to the above-described defect is an exceptional case.
