the higher the number the bluer the color ,these are some great bulbs,excellant quality,and super bright light blue color . only way to get true blue light is with HID lights,these are as close as you get with non HID

To my knowledge, it is 4200 K with a light output of 3350 +/- 300 lumens. Higher temperatures do not mean brighter bulbs. Higher temperature bulbs put out less light.

For LED RGB light, the color temperature of the white is about 6000K to 7000K. Compare to a 12W halogen light bulb, which has about 2800K to 3000K, LED light bulb has 3000K to 4000K difference in temperature.

It's white 6000k has a bluish hue to it. These are a bright white they won't match HID lights.

The 4000k fixture has a slightly whiter light output than the 3500k. There is not a huge difference in the two but if your preference is towards a whiter light I'd go with the 4000k.

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.

In just a visual subjective opinion, it is somewhere between the 40-60w equivalent. But what I find unsatisfactory is the two bulbs I bought cast a coppery-golden hue skewing the color anything illuminated

2000k lower blue spectrum... if you are looking for the warm bulbs (red spectrum), I believe you have to look for 3000k (lumens I think you are looking for). They cost more than the regular ones this comes with. Just no matter what, always make sure proper wattage. Not worth risking fire.

Not sure, but it does closely resemble the color output of HID lights. 6K? Very light bluish tint, definately NOT yellow tint.

Actually 4000K to 5000K is more natural than the ugly yellow cheap bulbs we all grew up with. Any eye doctor will always recommend to avoid these yellow color bulbs are they are not natural light colors for reading or anything but ambience, and over time damage your eyes, which may lead to wearing glasses. Go outside, it's not yellow. Even graphic artist will not nor ever use a yellow colored bulbs as they affect the natural true colors. It's hard to switch but once you do your eyes will thank you. If 5000K is too white, then 4000K is a next good compromise.

In agreement with other answers, the bulbs are "white" without the yellow or even blue tinge. 7000K is a good answer or about the color of bright 92 and above printer paper.

The 2700k is pleasant light which looks very similar in appearance to a normal human Edison bulb.The 5000k is a very white harsh light like an old-fashioned fluorescent bulb.I bought some of each and returned the 5000k bulbs. I like bright white light but it was too much. Like the inside of a freeway tunnel.

Just eyeballing the lights (and without using any kind of instrument) I would say 4100K. They are definitely not a warm light.

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.

Yes, the color of light provided by this bulb is "white" which at 5000k is also referred to as "daylight."

Unfortunately the lumen specs is neither listed on the bulb nor the packaging. While the light output from this bulb is good the color temp is definitely not 6000K, please see my review.

From what I can tell the differences are the lumen output of 1038 vs 1200and the color range of light from 3000K vs 4000K with the 3000 being a warmer lightand the 4000 being a cooler whiteThese are the main differences that I see-
