C2: Efficiency of the main headlights?

Hello community, I changed the factory lamps for “Night Breaker” from OSRAM – according to manufacturer +90s. The effect, at least in the case of rain (of which there is just plenty here), is hoeflich worded Ernuehrend … … minimally better (in the sense of more equal) light distribution, minimal whiter light color, that was it. I couldn’t understand the extra power cheered by many users. Are the spotlights of the C2 so badly designed? Or do I just have to look for better Hope for the weather (although I can also take MTECs)? Greetings JePilein
