Light emitted is whiter than standard halogens, but still not pure daylight white. I believe the color temp on these bulbs is around 3100 vs around 2700 for regular halogens. If you seek pure daylight white, try PIAA Extreme White. PIAA's are considerably more costly.

Very cold. I wish they made a 3,000K. They make an amber, however it is a yellow-orange color and not a warm white alternative. Bulbbrite are you listening?? The day they make a warm white 1W LED, is the day I place them in every socket where a only gentle light is needed. Hope this helps.

You are asking for the Color Rendering Index (CRI) of the florescent tubes that ship with this product. Another way to put it is the color temperature, or light spectrum.I believe these are rated as natural sunlight or day light bulb around 500-600 Kelvins but do not quote me as I don't have the manufacture product specs. I would suggest you check with the manufacturer for that specific rating.As a gardener I find they work great for seed trays and plant starts. However, I'm not trying to grow anything exotic or medicinal.

The color temperature is listed as 3000; in my house, this is a neutral white. It is not the "warm white" of an incandescent (2700), and it is not the "cold blue" of a 5000 daylight. Hope this helps!

It gives a very white light. I don't know what the color temperature would be, but it is not a real warm or "reddish" color.

I don't know the color temperature, but the ones I received are a bright white rather than "warm" white.

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.

This bulb has a "Warm White" hue. It is not bright white like many LED's, it is fairly close to a normal incandescent MR16 light bulb, definitely "whiter" but not too white in my opinion.

I can't say the exact temperature but it is not a warm light at all. I would guess around 6000K.

The color is bright white (really neither blue or yellow) and I'm not sure about temp. I don't feel any heat when the lights are on. We put them on a dimmer so we can adjust according to our needs. They are very bright which might be a concern for some.

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.

Am not absolutely certain of color temperature, but believe it to be about 5000K, which is whiter than the "warm white". I prefer this higher temperature for reading, and have been very happy with these fluorescent replacements.

Not the hotter color that is sometimes described as daylight this is a cooler temp and is closer to the yellow of an ordinary incandescent but still it is LED, I used in outdoor fixtures and have for some years now, not the bluer white, note most bulbs are not the bluer hotter K light, just went through that with some other bulbs I bought at HD for lamps, the 6000K daylight bulbs are whiter than coolwhite etc. I would say these bulbs more like cool white, meaning a bit more yellow. The temp range should be good indication of what to expect, 3000-4000 is more yellow, up near 6000 is hotter and more bluewhite.

The color temp of the light is approximately 3000k so on the warmer side. Comparable to a Halogen light.

The color could be called warm white. It is as close to natural sun light as we have seen from any artificial light source. Almost all florescent bulbs tend toward the blue end of the spectrum. At 3000 Kelvin temperature, these LED's are very white with a slight shift toward the yellow, warmer end of the spectrum, very much like sunlight.

Was curious about this myself, so I measured the temperature with my infrared thermometer. The base of the bulb got surprisingly warm given the 4.5 watts, and measured around 150 degrees F or so. For reference, the 40w incandescent bulbs they replaced got to about 260 degrees F. So noticeably cooler, but still warmer than I expected.
