what is the bulb (equivalent) color temperature?
1655913
color temp= 5300-5500k; LED life 40,000+ hours; power consumption max 6W; brightness 400Im

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

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.

Good question; maybe would be clearer if you asked "color" temperature. I would expect about 5000K otherwise people would be complaining about blue garbage light.

Low color temperatures are red-yellow and exhibit a long wavelength, while high color temperatures are blue-violet and exhibit a short wavelength. By coloring a bulb yellow, then, the manufacturer has decreased the color temperature and in doing so increased the wavelength into a spectrum unseen by insects.

I don't see the kelvin # on this package, it may be on the back, does any one know? 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! Here's a webpage with an explanation and chart.http://www.lightbulbsdirect.com/page/001/CTGY/ColorTemp

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.

After researched our product listing, the warmest color temperature of our 4 watts MR16 is 3200K. Regarding to your requirement, we suggest you to try our 5 watts and 7 watts MR16 in 2700K. Below is the product link. 7 watt warm white: B00IUEN8F2 http://www.amazon.com/TorchStar-12V-MR16-LED-Bulb/dp/B00IUEN8F2/ref=sr_1_1?ie=UTF8&qid=1407349571&sr=8-1&keywords=B00IUEN8F2 5 watts warm white: B00IUER326 http://www.amazon.com/TorchStar-12V-MR16-LED-Bulb/dp/B00IUER326/ref=sr_1_1?ie=UTF8&qid=1407349615&sr=8-1&keywords=B00IUER326 Thank you!

My unit came with an Agrobrite 6400 K color temp T5 lamp. You can put in what ever you want. T5 bulbs are available in a variety of color temperatures.

2700K color temperature and color rendering index of 80 are close to as good as LED bulbs get. To completely match incandescent, LED bulbs will have to reach 2700K and 100 CRI. But I have a number of bulbs with 2700/80 that I am satisfied with in terms of warmth vs incandescent, especially considering the superior bulb life, reduced waste heat output, and lower energy costs.

I'll try to answer this question even though the wording is odd. If you are asking where on the color spectrum they are, they are 6500K on the color temperature spectrum. This is similar to the color of daylight on an overcast day. Not really on the blue or orange side of the spectrum. Pretty close to white light. I can't find a wavelength chart that breaks down the distribution of wavelengths for these bulbs.

Color temperature or Physical temperature? 1 - Color temperature wise these seem to have a cooler white/blue effect, but without being over the top. Can't give you an actual temperature though. 2 - Heat wise, it'll depend on what your OEM bulb and wiring harness were rated at. Even running a bulb 5W higher could inadvertently cause issues with your bulb housing and light itself. I can't agree with the previous posters sentiment the "light energy goes up then heat energy goes down". The strength of the light (measured normally in 'lumens') will typically increase as the bulbs wattage increases, as would surface/air temperatures.

Cool white, but I do not know operating temperature. We actually use it indoors on top of a kitchen cabinet pointed to the ceiling for reflective night lighting. It is effective for the kitchen, family room, and living room. However, I would not rate it as a 300 watt equivalent. Seems to be about 150 watt equivalent

No, not warm. Stark white. You would think the bulb manufacturers would put this information on their packaging

A 3000k color temperature in an LED is a whiter light than an incandescent with the same color temperature. The difference is the CRI (Google it). These LEDs have a CRI of 75. LEDs with a CRI of 80 to 85 at 3000k will appear warmer to the human eye at the same color temperature. Incandescent lights generally have a CRI of 95 or higher. Warm white florescent lights typically have a CRI in the 85 to 90 range. White LEDs with a CRI of 85 are hard-to-find and expensive.

I'm not sure about the CRI. But the bulb claims a color temperature of 2700 K.

Well, white, I guess. I use it in a reading light. What is the color temperature factor you mention?I think I just found identifying info:Osram 133531 - FPL18EX-N Single Tube 4 Pin Base Compact Fluorescent Light Bulb
