The delivery came thanks to Prime within 2 days (Sunday to The) than I expected.
The lamps are in the package again in a plastic mold, so here the Amazon package, an additional protection is (even if it again more packaging waste is produced).
In the evening, unpacked and screwed. The lamps correspond exactly to the previous R50 lamps, because in my lamp housing is the pear an additional glass ring which closes almost exactly with the lamp. There were no problems with the size.
After switching on the kitchen was so flooded with light, as I have not even experienced with the 60W bulbs. Of course, the light is not warm white, but in the kitchen, I can get over this very well. Here I want to see in cooking or rinsing something and this meet these lamps more than expected.
Now it's still on life that the LED bulbs justify the price.
Unless something (negative) results here, I will add this at this point.
For me it is clear that I have made the right move to "energy transition" with these lamps. Bit by bit I will now take the next room and switch to LED.
Update March 2015:
The LEDs still provide the same brightness. There are still not change my decision and vote to change.
Meanwhile, I have good 3/4 of our house converted to LED. None of the purchased LEDs has prepared this issues.
