I just built a one to detect a difference. And that is clear! The bulbs are much whiter, truly towards xenon-look. However, it can be seen even from the outside, that the brightness due to the strong blue coloration is smaller. Ernst it is in the dark in the rain. Several times I checked whether I had turned on the light. Neither the lighting range, more brightness correspond to the series-H7. I can not prove it with test results, but I see on the highway when overtaking other H7 lights. Both cars are on the same level, I see my light hardly or not at all. Also, it is difficult for me to understand the positive reviews.
So far, keep both bulbs almost 6 months at about 2 hours of runtime on 5 days a week, or around 240 hours.
Who is on optics, will be very pleased with these bulbs. A brightness increase in vain.
