Default Headlight Kelvin Value?

My C5 needs a headlight upgrade and there are a couple vendors on this forum writing about their "headlight projector upgrades".

Anyone that would pass along their opinion on selecting a Kelvin value to look for in an upgrade would be really appreciated.

My experience with "K" ratings is the bulbs used in my garage. There are multiple fluorescent fixtures mounted on a white ceiling and the first bulbs were very harsh and caused vision fatigue. Those were replaced with 5000K bulbs several years ago and they are very good.

Now I see headlight bulbs offered that are rated all the way up to 8000K. Wonder if that is ok out on the road - from my experience it would not be the best "K" value there either.

What do you think is the best?

IMNHO 5k is the way to go. Higher and you start to look like a Purple Honda Boy (not to mention lower light output). Lower and it starts to trend towards yellow. 5K is a good compromise.

You can't go wrong with anything RadioFlyer sells, if you haven't settled on a vendor.

Anywhere from 4000K, which is a slightly yellowish white to 5000K, which is a very slightly blueish white is fine. 4300K bulbs put out the most light, at approximately 3100 lumens, while the 4000 and 5000K put out about 3000 lumens.
I bought 5000K 55 Watt projectors from JW with the Hi-4 harness which lets the low beam HID lights stay on when going to high beam, so all 4 lights are on.
They put out a tremendous amount of light.

6000k is where you want to be...gives of a nice white/blue tint and plenty of useable light on the road..

5K in my opinion is great, 6K will give you a bluish light which I didn't like at all.

If you wear a baseball cap at work use 6000k or higher
If your over 20 and don't wear a ball cap at work use 5000K

OEM is 4300K in the HID/Zenon world. So 5K gets you the most light output with just a tinge of Blue. 8K is for kids that get giddy over all that blue light, they are the weakest in actual light output that goes down the road. Both my Z and my M3 have 5K Hids and I like them very much...

5k

by 6k you're getting into the blues and light is reduced in the rain. higher kelvin bulbs tend to do worse off shiny surfaces

Thanks everyone for your input, now all needed is settle on a vendor. That will be hard since all on this forum seem to be excellent.

I agree. We sell 6000k temps the most. 5000k is what I would suggest.

Good observation OP. Everyone wants to be in the lighting business. They're only competing by undercutting our prices. We have the most experience here out of them all. I've been selling these kits since 2008 when we first started. We custom modify these in house to make them plug n play where others make you guess. Our instruction booklet is 12 pages long. No guessing with our kits

Let me know if we can set you up.

Here's a rough breakdown:

3000K - golden yellow (good for fog lights, rally lights or adverse weather)

4300K - Halogen Yellow (OEM color for most vehicles)

5000K - Pure White (My personal favorite and most popular, this illuminates all objects in their natural color)

6000K - Sky Blue (you loose a little visibility for the added "blue"

8000K - Iceberg Blue (more for show than anything, Not very effective on the roads especially asphalt)

Anything over 6000K and you'll really be singing the blues.

I should also note it might induce nausea in some.
