What kelvin temperature are these? 6000k?

These are a "Cool White" LED . These will range from 6000k to 7000k to which batch of LED's they received, but do not usually go past 6500k .

Not sure on the kelvin rating, but yes they are a bluish white in color. Illumination in general is quite good.

Hi, Well I'm not sure, But I would say 60 degrees. You have to buy them. They work great. You will never buy a better brand.

What temperature are we talking about? I would not leave them out in direct sunlight at 100F.

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

I believe right around 5,000 Kelvin. They are white with slight blue tint. No brighter than holagen, but in my Windstar with no other light they do reach noticeably further. I won't go back to old holagen lamps. Just better LED's.

I don't see anything in the specs about operating temperature. So sorry, I can't give you a specific X-degrees. I used them in eight open track light fixtures in a kitchen, and did not sense any radiated heat. But they are definitely very hot to the touch, and I would not use them in closed fixtures. Actually, I've moved and have some leftover, which I don't need. Allen

These are closer to daylight color temperature - I'd estimate around 4500-5000K. Very bright pure white. Not recommended if you are looking for that low of a color temperature.

The output is White not Warm White, Can't give degrees Kelvin but definitely white white

Don't know. Have eight of them and no complaints. Light color is 3000 degrees kelvin. That's a little bluer than regular light bulbs.

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.

Do you mean, what are the 3 temperatures? They are low, medium, high. I have never used high as medium is quite warm enough. Hope this helped you.

Are you asking for the Kelvin color or for the Lumens? Neither is listed on the package, but the light is warm white is probably around 4000K (not too warm). The lumens are low and equivalent to a 40W bulb.

Please Google or Bing 『Color Temperture』 ? 5,000 K is Pure White. 2,700 K is a bit yellowish White. More like light from an Incandescent Light Bulb.

Those are the Kelvin Ratings. The 6000k is usually the most popular. The higher you go in the Kelvin Rating, you get more color in the light in exchange for visibility. So 6000k will be just slightly brighter than 8000k and 8000k will be slightly brighter than 10000k and so on but they will have more and more color to them. Its completely up to your preference on which one you choose. Hope that helps.

They are "warm" which is a misnomer because 3000 Kelvin isn't a yellow "warm" light but a more white light... Not quite flourescent.. but definitely not warm. All the LED bulbs use this warm/soft terminology which is very poor and misleading. "Soft" is 2700 kelvin which is warmer (although still not as warm as incandescent.)

Hi Tony, the packet label states +/- 2°F between 50°F to 86°F. For me the relative accuracy between comparative readings is sufficient. I hope this helps. Cheers, Ken
