Right... My N/S bulb has been temperamental since September and finally gave up the ghost today so time to replace it

I know they're D2S bulbs but what output would people recommend? 6000K? Lower? Higher?

ISTR that 6000K is the best from previous experiences :-/ I'll be buying from HIDS4U as recommended by others.

Thanks

4100k they're as close to OEM as possible. 

OEM bulbs are Philips 85122 which gradually lose levels of light to around 5000k over time.  The ones I've linked are 85122+ which are the same except are meant to stay at 4100k over the years.

Not sure why people choose bulbs with a blue tint and have a lower lumen output.

Now I'm slightly confused... I knew that standard fit was about 4100k but I thought (from my school recollections and current research) that the higher the k number, the brighter the light, up to a certain point where it goes too far. Sure sunlight is about 6500k :-/

k number has NOTHING to do with "brightness" as we use the word.. but is to do with the end of the spectrum the light is equal to. The higher the k number the "bluer" the light will be as it gets closer to the ultraviolet end of the spectrum.

The lower the k number the more "red" the light is.

Human eyes see a fairly narrow spectrum compared to animals, 4100 K is close to the light produced by "incandescent" bulbs.

6500 K has more "blue" and is "supposed" to work better on reflective surfaces like high vis jackets and the paint in white lines. Anything higher and you won't see "darker" objects .. like the pedestrian in a duffel coat.

As alluded to above .. the "brightness" of a light is measured in LUMENs and is a different ball game altogether..

Struggling to find a proper comprehensive chart to explain this, but this is what I've found in the mean time:

Yes... Sorry Nige, I should have put "brightness" as I am well aware that the Lumen is the SI unit for light intensity.

I wouldn't have gone any higher than 6000k as I know that it will become less effective. Perhaps I should consider 5000k as a good compromise :-/

I put 4300's in mine this week and the new Phillips is brighter against the old Osram.

Have a look here - - - > New HID bulbs fitted   

[I am a Daisy]

Have just fitted two new 6000k bulbs. This is my hirst time out with an Omega so dont know what the lights were like before as in how good the beam spread etc. I am finding the low beam with HID is very bright with a good spread but the main beam seems to be very, very poor. You can hardly tell its on main beam. Tried fitting 100W main beam bulbs, no difference. I am beginning to think that the 6000k bulbs are too bright having the effect of washing out the light from the main beam. Maybe Entwood or Shimmy  could shed some light on this lol

[cem_devecioglu]

using 6K for both cars..

4.3 too yellowish imo..

6K philips definitely crystal white no bluish..

noname 6K white (you can hardly say its bluish)

but 4.3 is more suitable for foggy days..

8K deffo bluish..

but as I understand the color tone varies depending on brand.. can be tested before purchase ..

Just for a giggle I popped into a large, well known motor factors today for a price.... £84+VAT... Each

Strangely enough I walked out and will order online in a mo

Just to add... I think I'll go for 5000k as a compromise between 4300 and 6000   I'll update when I've got them and fitted them (which may be a while )

[Tonka.]

I went into Vx and asked about them. £112+vat each, but are on TC, which knocked them down to £65+vat each.

On line was my choice as well
