“The Sylvania 9005 “SilverStar” highbeam bulb is advertised as making “whiter and 20% brighter” light, and this is supposed to improve the driver’s ability to use the light….What is obvious in comparing the “SilverStar” to the standard Sylvania high-beam bulb is that the SilverStar makes less light than a standard bulb. The difference at the brightest point in the beam is 77 foot-candles from the SilverStar, and 109 footcandles from the normal high-beam bulb. This equates to ~23% less light.”

Again, the raw quantity of light does NOT determine what you can and can't see ... or how well you can see it. Colour temperature plays a big role in that determination as it pertains to the road conditions at hand -- in addition to raw light output.

Thanks for the review Surreal. Just ordered some Philips Crystal Vision Ultra H1 to put in my new Spyder Projection headlights I'm installing in two weeks.
