Boobook, I agree with you post, with the brightness thing most people will see a whiter light compared to a yellow light as brighter but it may not produce a longer distance.
With the K chart I didn't go down any further then
orange,
orange was used as an example because any thing below 2500K is hard to buy for automotive headlight applications and are not for headlight use.
Anything below
orange is illegal for forward facing lights.
With going up to 14000K there are lights advertised for automotive use that are this rating.....don't know why any one want them.
The blue filtering is right, but it is still filtering out the lower spectrum of white light.
In a technical thing maybe Kelvin's is not the right rating to use but all light manufactures use it and most people understand it better and Kelvin's are more to do with temperature then light .
Differant types of light can have a differant K rating even is the same wattage
Sunlight is about 5600K but normal sunlight has a blue tint to it from our atmosphere.
When we sell HID kit we try and sell the customer the 4200K ones as opposed to 6000k
With HID's I would have to disagree that the are equivalent to 130 watt halogen lights.
Maybe we should start a science section...LOL.
