2700k is closest to incandescent.
2700k light vs 3000k. When the color temperature is 5000K or higher the light produced appears bluish white. 2700K is still slightly on the yellow-ish side. The difference between 2700 and 3000 is pretty small but you dont need to standardize either.
Warm White is around 3000k whereas Cool White is around 5000k. When it comes to the overall 1000K-10000K Kelvin scale theres not much difference between 2700K. A lower CRI regardless of color temp will cause colors to look strange and cause headaches for.
If you have any halogen bulbs eg. The difference between 2700K and 3000K can be seen with the naked eye although it is far from dramatic. 4000K is really the transitional color temperature that begins to turn the warmer yellow of 3000K into a cool white.
Lighting temperature typically comes between 2000K to 10000K. Suggested Total Brightness Level 4000 to 8000 Lumens. Use warm white bulbs and lights of either 2700K or 3000K in your living room.
Providing a traditional warm cozy feel to them or any room that. In my current remodel the kitchen looks best in 3000K. 3000K is where the color of the light starts to give off a softer-white glow.
Generally 2700K is very similar to 3000K but slightly more yellow. My rule of thumb is to go with 3000k in active areas like kitchen living room hallways etc and 2700k in relaxed areas like bedroom and dining room. SOFT WHITEWARM WHITE.
