Fluorescents aren't always "colder" though -- think "warm white" lamps.
I can get flos well-balanced with color temps from 2900K through 4600K,
but they're expensive (it is the balanced spectrum that makes them
expensive).
The real problem with standard flos is that they generally have a wicked
green spike in their output. It does lovely things to skin tones.
I think that what they're doing with the headlights is tossing out
technical terms that don't really have much meaning in the ordinary world
and using them as a selling point. Given enough lumens and a good
reflector design we could all be driving with those "brown-orange" sodium
vapor lights for headlights and our eyes wouldn't really care.

Yes, but in the short of it it is the gas in the bulb other wise why the

Re: Silverstar 9006XS/ST lowbeams vs standard Halogens
Using different gasses is a selling point. Xenon or krypton do pretty
much what halogen does in an incandescent light -- lets you run the
filament hotter and extends lamp life. HID lights are enclosed arc
lights, and there xenon is used to help the lamp restrike immediately when
hot (many types of enclosed arc lamps won't restrike hot and must cool
several minutes, not a good thing with headlights).
Xenon is also a buzzword and using in a tungsten light helps make unwary
buyers think that they're getting something much more snazzy than they
are. It is still just a glowing bit of wire in a glass bubble.
Bottom line: If you can see a blue filter in the lamp, you're filtering
out yellow light. Light that is filtered out is light your eye never gets
to use.

Re: Silverstar 9006XS/ST lowbeams vs standard Halogens
Using different gasses is a selling point. Xenon or krypton do pretty
much what halogen does in an incandescent light -- lets you run the
filament hotter and extends lamp life. HID lights are enclosed arc
lights, and there xenon is used to help the lamp restrike immediately when
hot (many types of enclosed arc lamps won't restrike hot and must cool
several minutes, not a good thing with headlights).
Xenon is also a buzzword and using in a tungsten light helps make unwary
buyers think that they're getting something much more snazzy than they
are. It is still just a glowing bit of wire in a glass bubble.
Bottom line: If you can see a blue filter in the lamp, you're filtering
out yellow light. Light that is filtered out is light your eye never gets
to use.

Re: Silverstar 9006XS/ST lowbeams vs standard Halogens
out of interest, how do you get a colour temperature of a match flame
at 1900K when wood burns at less than 500K ?
