I can not tell if my Coolnesfaktor increased by these burners, but I can see very clearly that I have now a fabulously good lighting (and only it does matter).
Here Osram probably many things right and if the life is exactly as good as the much darker burner factory previously, then hand the price / performance ratio.
Again thanks to an Amazon who transport damage handled very unbureaucratic!
Supplement for 3 night rides:
The light is remarkably pleasant and anything but yellowish. For my eyes it is a very bright white light.
