3000K vs. 4000K vs. 5000K LED light color temperature. It’s a matter of the user’s preference, material finishes, and room type (bedroom, kitchen, etc.). I recommend for indoor is to put 4000K in-active areas and 3000K in relaxed areas: bedroom, living room, the dining room at 3000 and the kitchen, passageways, bathrooms, laundry room at 5000K. The primary Kelvin range used in residential outdoor lighting is between 2700K-3500K. At the same time, we can use warmer color temperatures on architectural elements (between 2700k-3500K) and slightly cooler temperatures on plant material in a landscape (generally 3500k-4000k).
