Sylvania is an Osram label. I have been using Osram Silverstar bulbs (H7) for about 5 years, before that I used Philips Vison Plus bulbs. The Osram Silverstar bulbs have no blue tint, all Silvania bulbs appear to have that stupid (output-robbing) blue coating.
I recommend Osram Silverstar bulbs or Philips Vison Plus, either one in the non-tinted, clear configuration. Neither bulb lasts shorter than a non-premium bulb. The only reasons premium bulbs are brighter (+30 to +50%) has to do with perfect filament placement and possibly a superior gas filling. I can't speak for Sylvania, but I'd never buy a tinted bulb anyway.
