Just about to do mine although not h7. I got the cyclops kit which they do for the BMW bikes as well. They aren't the cheapest but the kit is comprehensive and they don't throw bulb errors.
Light output wise there isn't a big difference but they are instant on and should last longer. Much more useful for high beam which I never bothered with on HID conversions. I got the 6400 lumen kit so it should do the job.
