    I know a bit about a lot of stuff, but one thing I know nowt about is xenon bulbs and the different numbers used.

    Some internet research on the subject has revealed much conflicting info and I'm trying to make sense of it all.

    I'm specifically referring to the 'K' value of the bulbs and what it relates to in real terms. I understand it to be the colour temperature but some say the higher the number the brighter the bulbs are, but others say the higher the number the bluer they are and therefore lower brightness; if you want bright bulbs (more white) then you need bulbs with a lower number.

    What gives? Anyone actually clued up on this stuff please, rather than hear'say and "as I understand it" type opinions?

    Thanks.

    Your 2nd statement...higher the K value, the less brighter you get as you go into the purple band

    there is a thread(various threads) discussing this very thing

    K is the colour temparature and nothing to do with brightness but more to do with the colour it is...3800 is warm white 4300 is birghter and very white then the higher you go the less bright it appears as the colour changes more to a bluey-pink colour

    You are right, there are plenty, but they all talk about the blueness (k) and not the brightness (lumens). I'm not interested in the blueness particularly, I want bright bulbs but the problem is most of the ads selling them just rave about the amount of K they are and the blueness, without mentioning the lumens, so no use to me whatsoever, hence why I'm asking here if there's anyone that knows what the craic is.

    Well if you want the brightest then you would want 4300K 55watt bulbs....however 55watt bulbs are very blinding for other traffic...a bit over the top IMO.......


    In one thread there was a colour(K) vs lumens chart and 4300 was the brightest in that sense

    55w is for halogen bulbs??? Xenons are 35w from what I've read and can be different lumens at that wattage. That's why I'm trying to ask people that are clued up on them instead of hear'say (no offence intended).

    I did a bit of research before fitting my hid's, what I found was 4500 is argueable the best illumination, most oem lights are this colour but there is definately still a yellowish tint on the road, 6000 gives a white light, maybe you will lose a tad of illumination with 6000 but hardly noticeable, anything over 6000 tends to drift towards a bluey tint and loss of illumination. If I ever had to re-new them it would definately be 6000 again for me. 35 watt is plenty, any higher is getting into a dazzling situation.

    6000k is the best mixture of illumination and looks in my opinion. Pure white light on the road, excellent visibility, and the slightest bluey tinge from a distance.

    For ultimate visability, you want either 4300k or 4500k as mentioned. These look white when you stare the headlights lit up, but the light on the road is slightly yellow still.

    Xenon Conversion Kit bulbs are most commonly 35w, compared to halogen bulbs traditionally being 55w. 35w is more than enough on a xenon kit. As mentioned, you can get 55w xenon kits/bulbs, but these seriously hurt your eyes/other drivers.
