The pears keep in their sockets without any problems, length and width of course I measured before - fits.
Since everything is as expected and it was no problem, first time 5 of 5 stars when the first one fails, I will report myself here again, if I did not do that they shine still (about 12h a day)
Small Update December 2012: SIDN now all 4 pears daily at least for 3 months 14h in use, at about 6 switching operations per day.. No failures yet, not even a single LED as far as I can see (which are damn bright, falls since daily difficult;)
The only drawback, as the 4 now swallow only 12 watts, one tends to be at times, when you leave the room for 20 minutes once she also. When the power guzzlers sooner was I disciplined and have identified when I'm out of the room.
Oh yes, for info: the first 2 rows of LED watch from the lampshade with me, so it is reasonably well ventilated. Perhaps this also helps dfer life expectancy. If a bulb fails times as long as it is guaranteed, I will in any case write here what to do so if not, it can be assumed that the light still ...
EDIT 24/02/2014
---------------
So now are over 1.5 years - it's still none of Leutmittel, not even a single LED, failed.
But purely subjective, I would say that the luminosity by about 30% has gone back. At least it seems to me now much darker in the room before.
Bin but overall still satisfied, will soon sure again nachordern what and then I can say more about the loss of brightness)
