Xenon headlight bulb feature:

100% Brand new,Top quality,easy to install.
High-intensity discharge lamps(HID lamps) make more visible light per unite of electric power consumed than fluorescent and incandescent lamps since a greater proportion of their radiation is visible light in contrast to heat.
HID xenon lamps are usually applied to automotive headlights.

35W OR 55W, WHICH IS BRIGHTER?

Which HID color is brighter, 4000K, 6000K, or 10000K?

The first one is the way the HID bulbs get their color.
The second thing that attributes to the color is your ballast.
If you are using a 35-watt ballast, that means that the ballast only draws 35 watts of power, determining how bright the bulb gets.You can put a 45, a 50, or a 55-watt ballast on your bulbs too, and all that's going to happen is they will get brighter and have washed-out color.
Every time you increase the wattage of the ballast powering your bulb, the color shifts down.
The other thing that's going to happen is the brightness increase. You will get about a 50% brightness increase by going from a 35-watt ballast to a 55-watt ballast.
