OK, So These Extra-White Bulbs Aren't The Best Choice For Maximizing My Headlamps' Performance. What Should I Get Instead?
For those who want the best possible performance from their headlamps and are more concerned with their ability to see rather than the appearance of their headlamps, the major bulb companies offer optimized bulbs without the light-stealing blue glass. Narva RangePower+50 and RangePower+30, GE Night Hawk, and Philips Vision Plus, and Osram Silver Star are the ones to get.
Wait a Minute, Earlier You Said Silver Star Bulbs Have Blue Glass!
It's a name game: Osram, the well-established German lampmaker, sells a line of automotive bulbs they call "Silver Star". These are Osram's top-of-the-range headlamp bulbs, equivalent to Narva RangePower+50, GE Night Hawk, Philips VisionPlus, and Tungsram Megalight Premium. They produce the maximum legal amount of light while staying within legal power consumption limits. They have colorless clear glass.
Osram bought the well-established American lampmaker Sylvania in the early 1990s, so Osram is now Sylvania's parent company. Sylvania also sells a line of automotive bulbs they call "Silver Star", but it's not the same product. The Sylvania Silver Stars have blue glass. Light output is of legal levels, but as with all blue-filtered bulbs, you do not get more light from them. The Sylvania SilverStar bulbs have a very short lifetime, because the filament is overdriven to get a legal amount of light despite the blue glass.
To get the best possible seeing performance at night, don't choose extra-white bulbs.<ul><li><a href="http://www.danielsternlighting.com/tech/bulbs/blue/good/good.html">Safe, Legal, Blue...But Are They Any Good?</a></li></ul>

I have the Osrams, and I like them alot. They're about a year old now...
...and they "appear" to have dimmed to just the standard H7 brightness now. IMO, $40 a year isn't a terrible price to pay for a non-riced lighting upgrade from the crap azz stock headlights.
