I see that the cool white on here is listed at (5000k). Is that accurate? In your other posts, cool white is listed at 6000-6500k. Thanks.

Cool white has no exact definition but 4100 K color temperature is the most common for lights sold as "cool white" . Lights with a color temperature of 5000 K are generally considered "natural light" and 6100 is "daylight". Warm white is generally 2700 - 2900 K while bright white is 3000 - 3500 K

It is a nice white, light. I would say between 6000k-6500k. It seems about the same as my 20 watt LED light. Probably right around 6300k.

I would definitely say between 5000K and 5500K, not any higher. They are a pure white color. I can see how they might be considered blue-ish after looking at yellow incandescent bulbs for so long. Look here --&gt; http://www.lightenergysource.com/kelvintemp.htm for why I say they are pure white and not blue-ish.

My understanding is the 4300k is OEM white and the 5000k is OEM also but with a blue tinge. Not sure which is for sale here but would like to know also.

I would say the light is closer to 6500k (more blue than white). I found this annoying because even though I enjoy white light for daily tasks it is too white/blue for me to keep on during the night. It is also a lot brighter than I expected!

According to their description, it is 2800. Which sounds about right. It is decidedly a WARM white, in the yellow; which is consistent with the incandescent bulb it replaces. If you have sconces, these will work well there also because of their small size.

Not all of the white LED's appear to be the same color, and I did not see any documentation regarding color index. However, the whites appear to be in the cooler range, so I would suspect most are 6500K down to maybe 5000K.

I think they run cooler than warm, but not they didn't look blue. I'd guess around 2700 to 3000k.

Hey Phillip, not sure of the exact C/T, but according to some C/T charts I looked up online, I'd say it was at least 5-7000k

So, I got the 6k Crystal White bulbs and they look very blue, then I got the or 5k OME White (can't remember) for another car and they look much more white and brighter. Go much lower than 5k and they will look yellow, but the higher the number the less light (lumens) is projected. If you go 8k they will be more blue / violet and dimmer.

6000k is white with a hint of blue, 8000k is more blue. The higher the kelvin the darker the color and the less brighter the light. A lot of the brightness also has to do with the quality of the ballast as well as the headlight design.

They look a little whiter than stock, so maybe 4300K. The higher the temp, the bluer the light. For example, 3000K is yellow, 6000K is blue. White light delivers the best illumination and is found in the 4 to 5 range. I replaced only one side ( bought a pair for when the other side dies) and it is whiter and brighter than stock.

While still "warm white," they are slightly cooler than the traditional incandescent bulbs. I would estimate about 3000K vs. the usual 2700K. However they are not in the "daylight" category (6000K). You might notice a slight difference if you mixed bulb types.

I would describe it as bright white -- 5600K or higher. That's my best estimate given that it's already installed outside, and I can't easily compare it to a cooler bulb.

On mine White has almost a purple hue but on the one a friend got it seems close to the 5000k.

Since this is listed as the same color temperature as their "warm white" version of the product, I'm not sure how trustworthy this number is. But users report the actual color as a white color. For reference, the higher the number the warmer the color: 3000k is typical halogen, 2700k is traditional incandescent bulb. 4000 would be white.

"K" is color temperature, in Kelvins. 2700K is a "warm" (aka: closer to orange/red) color, 5000K is a cooler (more blue'ish) white. But the 900-series phosphors in this and other similar bulbs are intended to produce more accurate colors (light produced covers more of the spectrum), but they're less bright as a result.
