what is the difference between cool white and soft white bulbs?
63297
Bulbs that provide light at around 3000K to 3500K may be considered "white" or "soft white." Bulbs that provide light at around 4100K to 5000K are considered "cool white" and these start to have a slightly blue feel to them.

Here's a breakdown of light bulb color temperature: Soft white (2,700 to 3,000 Kelvin) is warm and yellow, the typical color range you get from incandescent bulbs. ... Warm white (3,000 to 4,000 Kelvin) is more yellowish-white. These bulbs are best suited for kitchens and bathrooms.

The Dusk to Dawn Light Bulbs are energy-efficient, using 85% less energy than a 60w incandescent bulb. They have a 12 month warranty and a 30 day money back guarantee. They screw in to a E26 socket, are 60W equivalent, have a cool white coloring.

Warm white vs. cool white. ... The color temperature of a light bulb determines whether white light will have a yellowish or bluish tint. Warm lights have lower color temperatures, and therefore appear more yellow, while cool lights have higher color temperatures, and appear whiter or bluer.

Soft white (2,700 to 3,000 Kelvin) is warm and yellow, the typical color range you get from incandescent bulbs. This light gives a warm and cozy feeling and is often best for living rooms, dens and bedrooms. Warm white (3,000 to 4,000 Kelvin) is more yellowish-white.

The three primary types of color temperature for light bulbs are: Soft White (2700K – 3000K), Bright White/Cool White (3500K – 4100K), and Daylight (5000K – 6500K). The higher the Degrees Kelvin, the whiter the color temperature.

The main difference between clear and frosted glass bulbs is simple; there is no color and no brightness. ... If you take a 40-watt bulb, it might be a 500-lumen bulb. Whether it's a clear glass or frosted one; it won't affect the brightness, but yes the difference between both bulbs lies in their looks.

Warm white (3,000 to 4,000 Kelvin) is more yellowish-white. These bulbs are best suited for kitchens and bathrooms. Bright white (4,000 to 5,000 Kelvin) is between white and blue tones. ... Daylight (5,000 to 6,500 Kelvin) has a more bluish tone.

Avoid LED lights above 3000K and/or labeled "bright white," "neutral white," "cool white," or "daylight white" as these lights will generally have a crisp, stark white color. LEDs with this light color contain a significant amount of blue light in their spectrum.

Warm white and soft white will produce a yellow hue, close to incandescents, while bulbs labeled as bright white will produce a whiter light, closer to daylight and similar to what you see in retail stores. If you want to get technical, light color (color temperature) is measured in kelvins.

Bright white (4,000 to 5,000 Kelvin) is between white and blue tones. With a less cozy and more energetic feel, bulbs with this color range are best for work spaces (such as a home office or garage) and kitchens with chrome fixtures. Daylight (5,000 to 6,500 Kelvin) has a more bluish tone.

CFL types. Most of the CFLs sold are not full spectrum. Mostly they are in two color types: warm and daylight colors. And instead of indicating the color of bulbs when lighted, people use Kelvin to measure the light color (or also light temperature).

Efficient. CFLs are four times more efficient and last up to 10 times longer than incandescents. A 22 watt CFL has about the same light output as a 100 watt incandescent. CFLs use 50 – 80% less energy than incandescents.

Compact fluorescent bulbs are vastly more efficient. They use up to 75 per cent less energy than incandescent bulbs, which means reduced greenhouse gas emissions from energy plants. Fluorescent bulbs also last up to 10 times longer.

Cool White, on the other hand, is a very bright, pure white light that can often read with hints of blue. It is more luminous than warm white and when LEDs first hit the commercial market they were all placed into the Cool White category because it was simply too costly to create a warm white LED.

Do LED lights emit blue light? Yes—but no more blue light (pdf) than other lightbulbs, provided they give off the same balance of shorter and longer light wavelengths. “Warmer” light has more of a yellow tone to it, while “cooler” light, which is similar to daylight, appears a little bluer.
