Have the been a while in my E34 as Abblendlichtleuchtmittel it and I must say I regret, that I have not already purchased earlier. Thought that the percentage is humbug. Although I can not say that it brings exactly 130% of the luminosity of a normal halogen H1, but what I can say is that the road is much better illuminated in front of me and I at night overland travel a lot to me safe feeling because I now at least the Chance had to detect obstacles earlier. Can buying these bulbs, regardless of frame shape, highly recommend.
