I was thinking of replacing my lowbeams with the Sylvania Silverstar
9006XS/ST,
but in looking at the specs, yes the color is whiter - vs halogen -
but the lumens appear to be the same - 1000 - as the standard halogen.
How can the Sylvania webpages show a "brighter" throw with the same lumens
and the reflector assembly is the same....

It is the gas used in the bulb plus the coating on the bulb that produces a
whiter light with the same lumens as a halogen which produces a yellowish
light.

Light has a temperature in addition to a luminance level. Some lights are
warmer or colder than another. This not temperature in the tactile
"hold/cold" sense. Some colder lights can appear to cast a light that more
brightly illuminates a subject. They do so at the sacrifice of color
accuracy or fidelity. As in, florescent lights are colder and make it
somewhat clearer to 'see' than incandescent. But the color balance suffers
because of it. I'd imagine the headlights are doing similar things.

Hmmm. Some confusion there.

Halogen is a gas used to charge the envelope of tungsten lamps. The gas
is there to encourage tungsten that has boiled off the filament to
redeposit itself on the filament when it cools, rather than on the wall of
the envelope. Apart from discouraging discoloration of the glass and
allowing somewhat higher operating temperatures it plays no major part in
light color in incandescent lights.

"Whiter" isn't necessarily brighter, and likely isn't all that "whiter"
either, more likely a shift towards blue. One way to achieve a shift
towards blue is to make the filament burn hotter, the other way is to
filter out yellow light. Filtering out yellow means that you lost lumens
that your eye can use at night.

The Sylvania 9006XS listed below consumes 55 watts and produces 1000
lumens with a color temperature of about 4000 degrees Kelvin. If you're
swapping lamps what you really want to know is watts consumed (load on
your wiring) and lumens of output (bang for your buck). The color
temperature just tells you how yellow or blue the light is and once your
eye adjusts to the color you won't notice it.

For comparison, the color temperature of a match flame is about 1900
degrees Kelvin (1900K), a household light bulb is 3200K, late afternoon
sunlight is about 4500K, a blue glass photoflood bulb is 4800K, an
overcast sky is 7000K and light coming from only blue sky is 10,000 to
20,000K.
