On a forum I came across the GE. Have now read more often that GE should be much cheaper than other brands. I can not confirm. The Osram have about 15, me - tasted Euro and the Bosch Plus 90 can be found here at Amazon for comparable price.
Nevertheless, I ordered the Pears to just try it. So last night and installed directly rotated a practice round.
Conclusion: The light is beautifully white, the bulbs shine very bright and wide.
Nevertheless Subjectively I can not detect any significant difference to the high-performance bulbs from other manufacturers.
Remains to be seen how long they keep.
