Although both are oftentimes considered to be warm white - there certainly is a noticeable difference in color between these two color temperatures.
2700k vs 5000k led. Would like to use LED wherever possible and I noticed that theres a lot of 2700K and 3000K LED potlights. 4000K appears as a cool white light when viewed on its own but when compared to a 5000K light 4000K looks to contain some yellow. In these areas there are more visual tasks.
It is mostly used in kitchens. The 2700K matches the warm soft light colour of candlelight firelight or an ordinary incandescent bulb. You can even use it in the kitchen when you work.
2800K and have a red-yellowish tone. The three primary types of color temperature for light bulbs are. Both can represent a traditional incandescent bulb color and can be used in residential areas like bathrooms kitchens living rooms or bedrooms.
For homes 2700K to 4000K LED lights are the best. Both 5000K and 4000K can be used in various wattages. A 3000K LED light has a larger mix of yellow but still not nearly as yellow looking as a halogen lamp which is commonly 2700K.
Actually the amount of lumens in a F40T12 for example bulb is the same regardless of the color. So its good for bathrooms basements area and your study room. I use 2700K for all of my inside bulbs because they are easier on my eyes and are more like the incandescent bulbs.
It is basically the measure of the temperature of the lights. A standard 60 W bulb will give a warm glow of about 2700K while most fluorescent lamps have a white light that is mostly neutral of 4000K or white and cold light of about 5000K. An LED with a Temperature of 2700K produces a very warm almost golden white light while 7000K is a very cool white that can in some applications appear to have a light blue glow.
