What color is the light produced by these? Is it a cooler, bluish light, or a warmer, yellowish light?

The light from these GE battery powered devices is white, cool, but not tinted blue.

They are a close to warm white; however, the diffusers i have in my existing lamps don't diffuse the light emitted from the replacement LEDs completely; as a result, you can see each LED instead of a single warm glow.

they produce a white light not a light blue that I associate with the "new" Christmas lights. this is a white white, they are bright. I live them

The light is blue. I haven't had any problems with them not working. In fact, my shipper sent extra batteries for when mine wore out and I haven't used any of them yet.

It's bluish compared to an incandescent. It's not as blue as natural sunlight (whose color temperature is 6000 k, but is actually "cooler" perceptually than "warm" white , which is the color of incandescents and halogens -- yellowish -- and is 2700-3000k). This light is probably around 4000k, which, compared to an incandescent, is cold and harsh. It says 3000k on the box but that's -- to put it nicely -- inaccurate.

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.)

The manufacturer indicates they are "warm white," which is generally around 2700K. My guess is that they are closer to 3000K. They are a quite pleasant color, not "blue" at all.

Warm light but still cooler than halogen. These are floods so there will be light splay and some willl reach you height it will not ne concentrated.

I decided not to purchase this bulb; I went with a Bulbrite LED globe light instead. But....from the research I've done online, 3000K is in the warm range so it should give off a warm, slightly yellow color - as opposed to the 5000 to 6000K light which are cool and decided bluish in color. The Bulbrite light I bought is also 3000K and I like it very much but I prefer the warm light glow as opposed to cool. Hope this is helpful

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.

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.

The bright white may be a little brighter than the cool white but they both have a bright white light whereas the warm white has a yellow cast to it. Not sure of the lumen's but I used them to replace the standard bulbs in my motor home and they are brighter and uses less power than my original bulbs. I love these bulbs.

No yellow - LED bluish. By the way. these lights are battery hogs and are fine for lighting in a confined space wherein you turn them on and off as needed. I do not recommend the motion detection feature because, at least in my kitchen, when used for under-counter lighting, the batteries didn't last one day.

I purchased a pair of these lights at the end of last summer. I would describe the color of the lights as a cool color. It is more blue than yellow.

I'm not sure what you mean about color temperature or light output. We just replaced the same ones that were in our track lighting in our living room as when we bought it. They are on a dimmer switch.

These lamps are not quite as warm as incandescent bulbs, but they are not a harsh blue either. I am using them in two bedrooms and a long hallway and the light is a clear white and brighter than the incandescent candelabra bulbs that I was using. They seem to be the same color temperature whether at full brightness or at a reduced brightness.

If you read the description, it says that these bulbs have a color temperature of 4100K. When looking at bulbs, the color temperature will range from 2700K which is a yellow light, up 6500K which is the blue light. Natural daylight is around 5300K (Daylight white), so these bulbs still have a touch of yellow to them, but they are much whiter than the standard bulb.
