Me too, so I contacted Sylvania, asking about the differences between
standard, XtraVision, CoolBlue and SilverStar. This is what they
replied:

"The XtraVision is a brighter product in terms of lumen output. The
increase in output on the XtraVision is by gaining a wider beam pattern
for better peripheral vision. The Cool Blue is a slightly higher color
temperature than the standard version, which gives it a whiter
appearance. A standard product is 3200 degrees Kelvin and Cool Blue is
at 3500
degrees Kelvin. The higher the color temperature the whiter the light
will be. The SilverStar has a color temperature of 4000 degrees Kelvin
and as I mentioned in the previous email, SilverStar also has the
redesigned filament and gas mixture to maintain a fuller beam pattern.
Down
road distance on all these products are the same. The difference is in
how intense the light output will be and the color of the light output."

Good info... What you should do is pick up the OSRAM Silverstars (Made in
Germany). These are different from the Sylvania Silverstars even though
Osram and Sylvania are the same company. I got mine from
DanielSternlighting.com. I changed my Civic's bulbs (stock) to these ones
and I was pleasantly surprised.

It;s a good investment

Lumens are a bad measures of automobiles lighting. Here is why:

lumen [n] a unit of luminous flux equal to the amount of light given
out through a solid angle of 1 steradian by a point source of 1
candela intensity radiating uniformly in all directions

candela [n] the basic unit of luminous intensity adopted under the
System International d'Unites; equal to 1/60 of the luminous intensity
per square centimeter of a black body radiating at the temperature of
2,046 degrees Kelvin

One lumen is the equivalent of 1.46 milliwatt (1.46 x 10-3 W) of
radiant electromagnetic (EM) power at a frequency of 540 terahertz
(540 THz or 5.40 x 1014 Hz). Reduced to SI base units, one lumen is
equal to 0.00146 kilogram meter squared per second cubed (1.46 x 10-3
kg multiplied by m2 / s3).

Therefore, depending on how you measure, a lumen is is only the light
output at 2046 Kelvin OR the equivilent or the equivalent light output
a 2046 Kelvin body would have.

Since the human eye does not absorb all frequencies with the same
sensitivity, this is a moot measurement. On top of that, lumens are a
measure of DIRECT light. Since as drivers we don't stand 40 feet in
front of our cars looking at our own headlights, it is also stupid to
measure the light from that point. What SHOULD be measured is the
amount of light reflected back to the driver's eye from a known
reflective body (i.e. a green road sign, a red stop sign, etc) in a
frequency-dependant manner based on the human eye. No one has EVER
used this type of measurement that I know, and as such, all talk of
lumens and "illegal" bulbs is a pointless endeavor.

Not true. For light sources that are not 555 nm monochromatic, a
standardized weighting curve is used. The human eye perceives x lumens
to be equally bright regardless of what color the light is, but 1 lumen
at 600 nm corresponds to more than the 1.45 mW it corresponds to at 555
nm.
