An excerpt from one of automotive lighting engineer Daniel Stern's articles: "These colored bulbs, whether it's Sylvania's Silverstar, Wagner's
Tru-View, General Electric's Super Blue, PIAA's Xtremewhite, etc., do not
produce "blue" light. They tint the light *in the direction of blue* to
produce a visual appearance that is "whiter" and "brighter". "Brighter"
does not mean there's more light -- it's a subjective visual appearance
only. More light is indicated by the term "more intense", which you'll
notice the marketers of blue bulbs stay away from, because these bulbs do
not make your headlamps more intense. You may also see reference to these
kinds of bulbs producing light of a "higher color temperature". That's
another way of saying the same thing: The light is tinted in the direction
of blue." [/QUOTE]
