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. Cool color temperatures of 3500-4100K are brighter, offering a “cleaner” look. Full spectrum color temperatures are between 5000K-6500K. This light is very bright and pronounced. Typically perceived as harsh, full spectrum color temperatures are rarely used in homes. 4000K is a cooler, whiter colour than 2700K and 3000K. It's the lamp that has traditionally been used in offices, waiting areas and most commercial applications. This is commonly called 'cool white', or occasionally 'neutral white'. 6500K is a very cool white that is used to simulate day light. Color Temperature is a bulb color rating that is measured on the Kelvin scale (K). The higher the color temperature, the whiter the color. 3500K Use this color for general household and office lighting where soft lighting is not desired. 4100K Cool white gives a whiter light.

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 lower the Kelvin numbers the yellow the color of the lights gets whereas, with higher Kelvin number, the light gets whiter and brighter. A kitchen needs warm colored bulb ranging from 3000K to 4000 K. And study areas need 5000K to 6000K LED bulbs for a bright daylight color.
Color temperature is measured in Kelvin (K), and there are three common ranges: Warm Light (2700K-3000K); Cool White (3000K-5000K), and Daylight (5000K-6500K). Warm Light resembles the color of an incandescent; looking orange or yellow.
In addition, a color temperature which is above 5000K can be termed as cool colors and 2700K to 3000K is termed as warm colors. Basically, the whiter or brighter the color temperature the higher the Kelvin degrees.
A light bulb that produces light perceived as yellowish white will have a color temperature of around 2700K. As the color temperature increases to 3000K - 3500K, the color of the light appears less yellow and more white. When the color temperature is 5000K or higher the light produced appears bluish white.
The ideal color temperature depends on the daylight hours. A pre-set color temperature of screens in 6, 500 Kelvin. For the eyes, it is best to keep the blue light out.
For example, in a small room, 5000 lumens will feel a lot brighter to the eyes than in a larger room double that size. While a room of 250 square feet will usually require 5000 lumens, it is important to note this is for general lighting and you may still need to add additional light around the room.
2700K is a similar colour appearance to incandescent lamps and is a warm, relaxing colour. 3000K is a similar colour appearance to halogen lamps with a warm but crisper colour than 2700K. Commonly called 'warm white'. 4000K is a cooler, whiter colour than 2700K and 3000K.
Warm white (3, 000 to 4, 000 Kelvin) is more yellowish-white. These bulbs are best suited for kitchens and bathrooms. Daylight (5, 000 to 6, 500 Kelvin) has a more bluish tone. This light color will maximize contrast for colors, making it ideal for working, reading or applying makeup.
The Brightest Standard Size Bulb: The Philips 1600 Lumen LED Bulb is the brightest LED bulb that fits in common household fixtures and lamps. It costs about $18. The Brightest “Warm White” LED Bulb: The SANSI 27W A21 Dimmable LED Light Bulb. This bulb is warm white and produces 3500 lumens.
The higher is LED temperature, the more it goes to blue and even purple. 5000K is less, than 6000K, so 5000K is natural white, which makes this color be close to light yellow, while 6000K is a higher temperature, which makes look somewhat blueish (cool white).
The color temperature of sunlight above the atmosphere is about 5900 K. The Sun may appear red, orange, yellow, or white from Earth, depending on its position in the sky.
