Installed these as H1 lowbeams in my Audi A6 C4 projector headlights to replace Osram Nightbreaker H1 Halogen bulbs. These Osram halogen bulbs are pretty much the best and brightest halogen bulbs available within OE power levels(50-60W).The cutoff is very precies - no surprise due to the projector - and both brightness and range has improved noticeably. Light beam also looks more focused while slightly narrower maybe ?I'm happy with the purchase. Will update the review if they fail or diminish prematurely.
