Cool white is brighter. As a comparison warm white is more like the yellow of headlights on older cars. Cool white is more of the halogen type of headlight color on new vehicles.

Cool white is brighter. Warm white has more yellow in the light and is therefore a little less bright.

Warm. It's slightly cooler than incandescent. Exactly the same as halogen. The color remains the same when dimmed, unlike incandescent which gets warmer.

The kelvin rating, cool is around 6500k which is closer to a white light, giving illumination that maintains a trueness of colour. Warm has an orange/red tint.

Cold white, and fairly dim. If you're replacing halogens like I did, you'll need more to get the same amount of light.

No, these are is listed at 6,000k which puts them at the high end of "daylight". It is really "white". Warm white refers to a color temperature around 3,500k.

A warm white- think more like the paint color Swiss Coffee that is used by most builders. Not crisp bright white like typing paper. If you have warm colors in your room you should be fine. If your room is more purples, blues, greens and bright white- this will look a little warm in toned for the decor.

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.

They are definitely warm white. I put them on the columns in front of my home and they near perfectly match the warm white icicle lights previously purchased from my local Sams Club.

Warm white is much better in the outdoors. As landscape lighting designer and installer I can tell you you will not be happy with the harsh effect a white light will give you outdoors.

Cool is generally bluish, warm is yellowish. This light is a white, medium warm light. Very pleasant on the eyes in the middle of the night. As noted in another answer, it is easy to adjust brightness to your own preferences. Also, the auto on/off lags by about 15-30 seconds - not a problem, just noticeable.

I chose the white because the blue gives me a headache. The majority of the students (108) also preferred the white. I don't know that it is necessarily warmer, but it made my eyes and head feel 100% better than the regular light.

Cool white is you're bright led light and helps from making the room too hot. Its not a big light bulb but its better then the regular light bulbs. Plus it helps lowers the electric bill by 30% and I recommend it to anyone.

Cool white and bright white are usually the same. Warm white - the other common type - typically has a more yellowish color to it and more closely resembles an incandescent light bulb.
