They can't be knockoffs, Sylvania is the child company of Osram for the USA market. Sylvania is really 'Osram Sylvania'
The Osram Silverstar 2.0 bulbs are a newer design of the Silverstar bulbs with higher output than the Silverstar Ultra's (10%) with a better lifespan. I used them in my Eclipse and they were great, but do you feel they are enough? Or if you had the choice, would you go with a bulb with even higher output with less life? There isn't an Equivalent of the Night Breaker made by Sylvania. Have to order from Europe!
