On the MV6 Estate 2001 are the HID bulbs D2S 4100K's or are they D2S 6000K's ?

And can the D2S 6000K's be fitted in place of D2S 4100K's as an upgrade or does the ballast box need to be changed as well ?

The headlights on my estate are absolutely crap when driving in the rain and not a lot better in the dry. I've cleaned the glass so it's not that, they've been like it since i've had the car.

yes, all the temp is, is the colour, 4300K is yellower, 6000 is whiter
8000 is blue / purple

So the 6000 would be brighter than the 4300 and the 8000 would be brighter than the 6000 then, or would there just be a different tint to the light emitted ?

yes and no....  Apparently the optimal illumination is circa 4100 although the perceived brightness is best at 6000.  The 8000 is really no more than a colour change.  theres a series of pics in the gallery where someone in the States changed lamps in a Catera and shows the different effects.  Will add the link later if you don't see it....

As I understand it .. the 6000k "look" brighter when you look at them, as the colour temp is higher, but due to the way the human eye actually "sees" things, via reflected light, the 4100K are actually better at night, they have more of the wavelengths that you need on order to see things.

This idea can clearly be seen using an LED torch. Such a torches "white" light is actually just 3 narrow bands of red, green & blue that gives the "appearance" of white. Take such a torch and try and look at a decent "family setting" type colour photo .. you know  wife, kids, trees.. something that has many different variations of colour, shades etc.

It will look very "washed" out and bland as the LED source does not have the wavelengths of light to reflect the "real" colours in the picture.

The same effect occurs when you use "high colour temp" bulbs ... white lines may look brighter .. but you might not see the child in a brown jacket against the trees.....

I think the 4100k is white enough, the 6000k is more icy white and might make you fogs and sidelights look a bit more yellow?

But 4100k are great to light up the road.
