I have in my car (Smart ForFour Brabus) four H7 bulbs. Two of them I have replaced them, the others are long-life bulbs from Osram (because of the change through the tubes of the intercooler is not fun). So I turned on the low beam and high beam and could immediately detect a distinct difference in the color of light. While the Bosch bulbs produce more yellowish light, the light of these bulbs is rather in White's.
For durability, I can not say anything when the pears but keep a year, my case is not enough. I'll adjust the review.
Incidentally, I have added an article image on which the difference of the two bulbs can be seen clearly.
