What is the color temperature of this lamp in degrees Kelvin, or at least in terms of "warm\cool"?

Thank you for your question, Mark! The color temperature of this fixture is 3000K, or warm white.

It seems to me the warm tones have some yellow/amber colored quality to them, while the cool tones have more white into blue tones. I personally do not care for the cool light tones in my house - they are either too bright or make everyone look grey. (imho). On the LED light bulbs - to replace incandescent bulbs - they sometimes show a spectrum and list the 'k' (kelvin) value - I kind of like the 2700k - it reminds me of incandescent lighting tones. Apparently this lamp can be purchased in cool or warm - since there are no bulbs to replace - I got the warm and I like it. -- hope this helps.

According to the package they came in, the light is considered warm. It doesn't list eh Kelvin rating. The best part is they fit in my regular medium sized desk lamps in the same socket I removed the incandescent 70W bulbs from. Can't wait o see if they make a difference in my monthly electric bill because I can replace about another 20 of them throughout the house. Hop this helps. Also box sys they have a 30 day guarantee.

Short answer: yes, it's a "hot" bulb, in that it's an incandescent bulb (not a CFL or LED). Longer answer: color temp theoretically is related to heat (so-called "black body radiation" by physicists)- such as a blacksmith heating a steel bar in a forge. At first the bar turns red, then orange, yellow, etc, as it gets hotter. Red is a relatively "cool" color, blue is a "hot" color. Ironically, bulbs marketed as "cool white" have a higher color temp (are bluer) than warm white (yellower). While their color temps are different, each can give off the same amount of heat, though. AFAIK, all headlight bulbs are incandescent (hot), since CFL and LED bulbs can't be made bright enough. Some have higher color temps (look more blue- and in fact may be marketed as "cool blue") but they're still just as hot to touch (don't touch!!!). They look blue because of different gases in the bulb (xenon), or tinting the bulb blue. This might be TMI.

I can't give you a scientific answer to your question but I can say this; i put them in a desk lamp using a 60W incandescent and in a ide lamp of a pole lamp using a 40W incandescent, and in both of those places, the Puilips bulb looks brighter to me. But I son't want to mislead you. I really have no idea about what color temperatures looks like. I did n''t even know colors had temperature. I'm jut giving you my "what it seems like by my eye view. I hope this helps.

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.

Hello Jimmy, The lamps you are inquiring about is warm white in color 2900K

they spec it in degrees kelvin. compared to other leds I've bought, they are more yellow, natural sunlight. The dispersal seems fairly even over the 120 degree pattern.

Here is a link that shows how 4000K "looks" compared to other color-temperatures: http://www.ledwaves.com/About-Color-Temperature.html

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.

It's color temp is 2700 to 6500. It works ok as desk or reading lamp. For general therapeutic effect, I prefer nature bright sun touch plus. I have both

The top-end (brightest) light is capped at 4500 lumens. On a Kelvin light scale it's a bluish-white light, which could be enough for your photography project. I've tried looking up a conversion scale, but those 2 units seem to be difficult to relate quantitatively, since it's not a bulb that you're measuring--high intensity LEDs instead. If you look up fluorescent bulbs, 4650 lumens delivers about 5000 Kelvin temperature light.

k stands for Kelvin which is the standard unit of measure for color "temperature" of light. It is not temperature as we normally use the term. Think of it as a numerical value for how warm or cool the color of a light bulb is. 6500 k would be a cool blue light.

The brightness is coded "warm" "bright" "cool". Cool is like a flourescent lights in a doctor's office. The warm setting has a yellow-ish coloring that's very relaxing on the eyes in my opinion. You can vary the brightness between Cool & Warm by turning a knob on the arm of the lamp. I like this lamp very much. It works very well for me. I have it set in front of my computer on my desk.

Buried in the description is "these bulbs are a 5,000K Daylight color". Light Bulbs are rated for Color Temperature, measured in kelvins. In my kitchen I prefer a `daylight' white light at about 5000 to 5200 kelvins. You'll notice the difference immediately if you mix bulbs in a multi-light fixture; one very white bulb makes the yellow ones seem REALLY yellow!

Can not help bought this for my son. You might try using Google by searching for 105w cfl. Will need to know the Kelvin temperature of the Bulb like 6500k or 5000k.
